In addition, the display unit 151 may be configured as a stereoscopic display unit 152 displaying a stereoscopic image.

Here, the stereoscopic image represents a 3-dimensional stereoscopic image, and the 3-dimensional stereoscopic image realizes the gradual depth and reality of objects on the monitor or screen. This is a video that allows you to feel the same as the space. The 3D stereoscopic image is implemented using binocular disparity. Binocular parallax means parallax caused by the position of two separate eyes. When two eyes see different two-dimensional images and the images are transferred to the brain through the retina and fused, the depth and realism of the stereoscopic image can be felt. .

A three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glasses-free method), or a projection method (holographic method) may be applied to the stereoscopic display unit 152.

In general, a 3D stereoscopic image is composed of a left image (left eye image) and a right image (right eye image). Depending on how the left and right images are combined into a 3D stereoscopic image, a top-down method of arranging left and right images up and down in one frame, left and right images in one frame L-to-R (left-to-right, side by side) method, which is arranged as a checker board method, which arranges pieces of left and right images in tile form, and left and right images in columns Or, it is divided into an interlaced method in which rows are alternately arranged, and a time sequential (frame by frame) method in which left and right images are alternately displayed by time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and the right image, respectively, of the original image frame, and combine them to generate one 3D thumbnail image. Generally, a thumbnail refers to a reduced image or a reduced still image. The thus generated left image thumbnail and right image thumbnail can be displayed with a distance difference between left and right on the screen by a depth corresponding to the parallax between the left image and the right image, thereby displaying a three-dimensional sense of space.

The left and right images required for the realization of the 3D stereoscopic image may be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit is configured to receive a 3D image and extract a left image and a right image therefrom, or receive a 2D image and convert it into a left image and a right image.

On the other hand, when the display unit 151 and a sensor for detecting a touch operation (hereinafter referred to as a “touch sensor”) form a mutual layer structure (hereinafter referred to as a “touch screen”), the display unit 151 outputs In addition to the device, it can also be used as an input device. The touch sensor may have, for example, a form of a touch film, a touch sheet, or a touch pad.

The touch sensor may be configured to convert changes in pressure applied to a specific portion of the display unit 151 or capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor may be configured to detect not only the position and area where the touch object is touched on the touch sensor, but also pressure at the touch. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen or a stylus pen, a pointer, and the like.

If there is a touch input to the touch sensor, the corresponding signal(s) is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180. Accordingly, the control unit 180 can know which area of the display unit 151 has been touched, and the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of a mobile terminal surrounded by the touch screen or near the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object in the vicinity using mechanical force or infrared light without mechanical contact. The proximity sensor 141 has a longer lifespan and a higher utilization than the contact sensor.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is a capacitive type, it is configured to detect the proximity of the pointer by a change in electric field according to the proximity of an object having conductivity (hereinafter referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of description, an action of making the pointer to be recognized as being positioned on the touch screen without touching the pointer on the touch screen is referred to as a “proximity touch”, and the touch The act of actually touching the pointer on the screen is referred to as "contact touch". The location on the touch screen that is a proximity touch with a pointer refers to a location where the pointer is perpendicular to the touch screen when the pointer is touched close.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.). Information corresponding to the sensed proximity touch operation and proximity touch pattern may be output on the touch screen.

When the three-dimensional display unit 152 and the touch sensor form a mutual layer structure (hereinafter referred to as a'stereoscopic touch screen'), or when the three-dimensional display unit 152 and the three-dimensional sensor for detecting a touch operation are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

As an example of the 3D sensor, the sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144.

The proximity sensor 141 measures a distance between a sensing target (eg, a user's finger or a stylus pen) and a detection surface that applies a touch without mechanical contact using an electromagnetic field force or infrared rays. The terminal recognizes which part of the stereoscopic image is touched using the distance. In particular, when the touch screen is a capacitive type, it is configured to detect the degree of proximity of the detection object by changing the electric field according to the proximity of the detection object, and to recognize a 3D touch using the proximity degree.

The three-dimensional touch sensing unit 142 is configured to detect the intensity or duration of a touch applied on the touch screen. For example, the three-dimensional touch sensing unit 142 senses the pressure applied to the touch, and when the pressing force is strong, recognizes it as a touch on an object located farther from the touch screen toward the interior of the terminal.

The ultrasonic sensing unit 143 is configured to recognize location information of a sensing target using ultrasonic waves.

The ultrasonic sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasonic sensors. The optical sensor is formed to detect light, and the ultrasonic sensor is formed to detect ultrasound. Since light is much faster than ultrasound, the time for light to reach the optical sensor is much faster than the time for ultrasound to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source by using the time difference from the time that the ultrasound reaches the light as a reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. When the distance information detected by the laser sensor is added to the 2D image photographed by the camera, 3D information may be obtained.

As another example, a photo sensor may be stacked on a display element. The photo sensor is configured to scan the movement of the sensing object close to the touch screen. More specifically, the photo sensor mounts photo diodes and TRs (transistors) in rows/columns to scan the contents placed on the photo sensor using electrical signals that change according to the amount of light applied to the photo diode. That is, the photo sensor calculates the coordinates of the sensing object according to the amount of change in light, and thereby acquires the position information of the sensing object.

The audio output module 153 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, call mode or recording mode, voice recognition mode, broadcast reception mode, or the like.

The sound output module 153 may include a receiver, a speaker, and a buzzer.

The alarm unit 154 outputs a signal for notifying the occurrence of an event in the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, and touch input. The alarm unit 154 may output a signal for notifying the occurrence of an event by using other forms, for example, vibration, in addition to a video signal or an audio signal. The video signal or the audio signal may also be output through the display unit 151 or the sound output module 153, so that the display unit 151 and the sound output module 153 may be classified as part of the alarm unit 154. .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the tactile effect generated by the haptic module 155 may be vibration. The intensity and pattern of vibration generated by the haptic module 155 may be controlled by a user's selection or setting of a control unit. For example, the haptic module 155 may synthesize and output different vibrations or sequentially output them.

In addition to vibration, the haptic module 155 is used for stimulation such as pin arrangement that vertically moves with respect to the contact skin surface, jet or suction power of air through a jet or intake, grazing on the skin surface, contact with an electrode, and electrostatic force. Various tactile effects can be generated, such as the effect caused by and the effect of reproducing the feeling of cold and warm using an element capable of absorbing heat or generating heat.

The haptic module 155 may not only deliver the tactile effect through direct contact, but may also be implemented so that the user can feel the tactile effect through muscle sensations such as fingers or arms. Two or more haptic modules 155 may be provided according to a configuration aspect of the mobile terminal 100.

First, referring to FIG. 2A, the communication system may use different radio interfaces and/or physical layers. For example, in a radio interface usable by a communication system, frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA) ), Universal Mobile Telecommunications Systems (UMTS) (especially, Long Term Evolution (LTE)), Global System for Mobile Communications (GSM), and the like.

Hereinafter, for convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including CDMA wireless communication systems.

As shown in FIG. 2A, the CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) 270, and at least one base station controllers (BSCs) 275. ), a Mobile Switching Center (MSC) 280. The MSC 280 is configured to be connected to a Public Switched Telephone Network (PSTN) 290 and BSCs 275. The BSCs 275 may be paired with the BS 270 through a backhaul line. The backhaul line may be provided according to at least one of E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Accordingly, a plurality of BSCs 275 can be included in the system shown in FIG. 2A.

Each of the plurality of BSs 270 may include at least one sector, and each sector may include an omni-directional antenna or an antenna pointing in a specific direction radially from the BS 270. Also, each sector may include two or more antennas of various types. Each BS 270 may be configured to support multiple frequency allocations, and the multiple frequency allocations may each have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency allocation can be referred to as a CDMA channel. BS 270 may be referred to as Base Station Transceiver Subsystems (BTSs). In this case, one BSC 275 and at least one BS 270 may be collectively referred to as a “base station”. The base station may also refer to a “cell site”. Alternatively, each of the plurality of sectors for a particular BS 270 may be referred to as a plurality of cell sites.

As shown in FIG. 2A, a broadcasting transmitter (Broadcasting Transmitter, BT) 295 transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT 295.

In addition, FIG. 2A shows the satellite 300 of a Global Positioning System (GPS). The satellite 300 helps to locate the mobile terminal 100. Although two satellites are shown in FIG. 2A, useful location information may be obtained by two or fewer satellites. The location information module 115 illustrated in FIG. 1 cooperates with the satellite 300 illustrated in FIG. 2A to obtain desired location information. Here, the location of the mobile terminal 100 may be tracked using all techniques capable of tracking a location, as well as GPS tracking technology. Further, at least one of the GPS satellites 300 may selectively or additionally be responsible for satellite DMB transmission.

During typical operation of a wireless communication system, BS 270 receives a reverse link signal from mobile terminal 100. At this time, the mobile terminal 100 is connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the specific base station 270 is processed within the specific base station 270. Data generated as a result of the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between base stations 270. In addition, the BSCs 275 transmit the received data to the MSC 280, and the MSC 280 provides an additional transmission service for connection with the PSTN 290. In addition, similarly, the PSTN 290 is connected to the MSC 280, the MSC 280 is connected to the BSCs 275, and the BSCs 275 are transmitted to the mobile terminal 100 in order to transmit the net link signal BS ( 270).

Next, in FIG. 2B, a method of obtaining location information of a mobile terminal using a Wi-Fi Positioning System (WPS) will be described.

The Wi-Fi Positioning System (WPS) 300 moves using a WiFi module provided in the mobile terminal 100 and a wireless AP (Wireless Access Point, 320) that transmits or receives a wireless signal with the WiFi module. As a technology for tracking the location of the terminal 100, it means a location localization technology based on a wireless local area network (WLAN) using WiFi.

The Wi-Fi location tracking system 300 includes a Wi-Fi location server 310, a mobile terminal 100, a wireless AP 330 connected to the mobile terminal 100, and a database 330 in which arbitrary wireless AP information is stored. It can contain.

The Wi-Fi location server 310 extracts information of the wireless AP 320 connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP 320 connected to the mobile terminal 100 is transmitted to the Wi-Fi positioning server 310 through the mobile terminal 100, or from the wireless AP 320 to the Wi-Fi positioning server 310. Can be sent.

Based on the location information request message of the mobile terminal 100, the information of the extracted wireless AP is MAC Address, SSID, RSSI, channel information, Privacy, Network Type, Signal Strength and Noise Strength It may be at least one of.

As described above, the Wi-Fi location server 310 receives the information of the wireless AP 320 connected to the mobile terminal 100, and includes the information included in the pre-built database 330 and the received wireless AP 320. By comparing the information, the location information of the mobile terminal 100 is extracted (or analyzed).

Meanwhile, in FIG. 2B, as an example, wireless APs connected to the mobile terminal 100 are illustrated as first, second, and third wireless APs 320. However, the number of wireless APs connected to the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located. The Wi-Fi location tracking system 300 can track the location of the mobile terminal 100 when the mobile terminal 100 is connected to at least one wireless AP.

Next, looking at the database 330 in which arbitrary wireless AP information is stored in more detail, various information of arbitrary wireless APs disposed in different locations may be stored in the database 330.

Information of arbitrary wireless APs stored in the database 300 includes MAC address, SSID, RSSI, channel information, privacy, network type, latitude and longitude coordinates of the wireless AP, building name where the wireless AP is located, number of floors, and indoor detailed location information (GPS coordinates available), AP owner's address, and phone number.

As described above, since the arbitrary wireless AP information and the location information corresponding to the arbitrary wireless AP are stored together in the database 330, the Wi-Fi location server 310 is a mobile terminal 100 in the database 330. By searching for wireless AP information corresponding to the information of the wireless AP 320 connected to and extracting location information matching the retrieved wireless AP information, the location information of the mobile terminal 100 can be extracted.

Then, the location information of the extracted mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location positioning server 310, so that the mobile terminal 100 can obtain location information.

Hereinafter, when a user grips (holds) the mobile terminal 100, a touch operation that occurs when a specific area of the touch screen (eg, a bezel area) is touched. ) And a control device and method of the mobile terminal that can be prevented.

3 is an exemplary view showing a state in which the mobile terminal 100 is gripped (grabbed) by a user.

3, when the user grips the mobile terminal 100, the bezel area of the touch screen is touched by the user.

4 is an exemplary view showing a bezel area of the touch screen of the mobile terminal 100.

As illustrated in FIG. 4, the bezel area 4-1 of the touch screen may include a first bezel area located on the left side of the touch screen and a second bezel area located on the right side of the touch screen. The bezel area 4-1 of the touch screen may be composed of a first bezel area located on the left and top sides of the touch screen and a second bezel area located on the right and bottom sides of the touch screen.

The width W _g of the bezel area 4-1 may be preset by the designer or may be set by the user. For example, when the bezel area 4-1 is dragged (moved) to the left or right by the user, the controller 180 determines the width W _g from the dragged position to the outer edge of the touch screen. Reset as the bezel area 4-1.

The control unit 180 receives a touch input to a bezel area of the touch screen of the display unit 151, detects a change in coordinates corresponding to the touch input, and transmits a touch input to the touch input based on the detected change amount. The corresponding touch information is blocked.

5 is an exemplary view showing a configuration of a control unit of a mobile terminal 100 according to embodiments of the present invention.

The controller 180 includes a touch input processor 501 that generates a control signal for blocking touch information corresponding to the touch input when the detected change amount is equal to or less than a reference change amount as shown in FIG. 5; A switch 5022 for blocking touch information corresponding to the touch input may be included based on the control signal. A plurality of touch input processors 501 and a plurality of switches 502 may be configured to process multi-touch inputs (touch input 1, touch input 2, and touch input N). The touch information corresponding to the touch input indicates information including an x coordinate value, a y coordinate value, a touch area size, and an occurrence time from a touch start point to a touch end point.

The controller 180 has an area (x coordinate value) corresponding to the touch input smaller than the width W _g of the bezel area 4-1 or at a width of the touch screen of the bezel area 4-1. If the width W _g is smaller than the subtracted value, touch information corresponding to the touch input may be output to the touch controller.

When the touch input to the bezel area 4-1 of the touch screen is received, the control unit 180 continuously receives the touch input for a preset reference time for recognizing that the user has drawn the mobile terminal 100. You can also judge (decide) whether it works. For example, the controller 180 determines whether a specific point of the bezel area 4-1 of the touch screen is continuously touched by the user for a preset time. That is, when the user grips the mobile terminal 100, a specific point of the bezel area 4-1 of the touch screen is touched by the user, and the touch state is generally maintained for a certain period of time. The preset time may be preset by the designer or changed by the user.

When the touch input is continuously received for a preset time, the controller 180 may block touch information (touch information) corresponding to the touch input. The controller 180 prevents a touch malfunction of the touch screen by blocking touch information corresponding to the touch input when a specific point of the bezel area 4-1 of the touch screen is continuously touched by the user. For example, when a user grips (holds) the mobile terminal 100, a touch false operation caused by touching a bezel area of the touch screen is prevented.

6 is a flowchart illustrating a control method of the mobile terminal 100 according to the first embodiment of the present invention.

First, the controller 180 determines whether a touch input to the bezel area 4-1 of the touch screen is received (S11). For example, the controller 180 determines whether a specific point (coordinate) of the bezel area 4-1 of the touch screen is touched by the user.

The controller 180 detects the minimum width (minimum width value) and maximum width (maximum width value) of the touch area (touch area) corresponding to the touch input (S12).

The controller 180 determines (judges) whether the difference between the detected minimum width and maximum width is equal to or greater than a preset reference value (S13).

When the difference between the detected minimum width and the maximum width is greater than or equal to a preset reference value, the controller 180 determines that the mobile terminal 100 is in a gripped state by the user. For example, if the difference between the detected minimum width and maximum width is greater than or equal to a preset reference value, the controller 180 blocks touch information corresponding to the touch input to prevent a touch malfunction of the touch screen (S14). That is, when a user grips (holds) the mobile terminal 100, a touch false operation caused by touching the bezel area of the touch screen is prevented.

7 is an exemplary view illustrating a touch area (touch area) when the mobile terminal 100 is gripped by a user.

As illustrated in FIG. 7, when a user grips (holds) the mobile terminal 100 and assumes that a bezel area of the touch screen is touched, an area touched on the bezel area (touch area) )(7-1), the X-axis width and the Y-axis width show a big difference. Accordingly, the controller 180 determines the minimum width (minimum width value) (X-axis width) and maximum width (maximum width value) (y-axis width) of the touch area (touch area) 7-1 corresponding to the touch input. When the difference between the detected minimum width and the maximum width is greater than or equal to a preset reference value, it is determined that the mobile terminal 100 is in a gripped state by the user.

The preset reference value is a reference value for determining whether or not the mobile terminal 100 is gripped by a user, and when the mobile terminal 100 is in a gripped state by the user, It may be a difference between a predetermined minimum width and a maximum width of the touch area (touch area) corresponding to the touch input to the bezel area 4-1. For example, assuming that the predetermined minimum width is 0.5 mm and the predetermined maximum width is 1 mm, the predetermined reference value may be 0.5 mm or more. The preset reference value may be changed by the user.

The control unit 180 may determine that the mobile terminal 100 is in a gripped state by a user when the detected maximum width is greater than or equal to a preset multiple (eg, 1.5 times) of the minimum width. The preset multiple may be changed by the user.

When the difference between the detected minimum width and maximum width is less than a preset reference value, the controller 180 outputs touch information corresponding to the touch input (S15). For example, if the difference between the detected minimum width and maximum width is less than the preset reference value, the controller 180 outputs touch information corresponding to the touch input to the touch controller.

The controller 180 may determine that the mobile terminal 100 is not in a gripped state by a user when the detected maximum width is less than a preset multiple (eg, 1.5 times) of the minimum width.

8 is an exemplary view illustrating a touch area (touch area) when a user intentionally touches a bezel area of a touch screen.

As illustrated in FIG. 8, when a user touches the bezel area to intentionally select content displayed on the bezel area, the X-axis width and the y-axis width of the touch area (touch area) 8-1 are the same. Or similarly. Accordingly, the controller 180 detects the minimum width (X-axis width) and the maximum width (y-axis width) of the touch areas (touch areas) 7-1 and 8-1 corresponding to the touch input, and the If the difference between the detected minimum width and maximum width is less than a preset reference value, the user determines that the content displayed in the bezel area is intentionally selected.

If the detected maximum width is less than a preset multiple (eg, 1.5 times) of the minimum width, the controller 180 may determine that the user intentionally selects the content displayed in the bezel area.

The control unit 180 blocks touch information corresponding to the touch input when the touch input to the bezel area is continuously received for a predetermined time and the difference between the detected minimum width and maximum width is greater than a preset reference value. By doing so, it is also possible to prevent the touch screen from malfunctioning. That is, when the user grips the mobile terminal 100, a specific point of the bezel area 4-1 of the touch screen is touched by the user, and the touch state is generally maintained for a certain period of time. The preset time may be preset by the designer or changed by the user.

Accordingly, the control device and method of the mobile terminal according to the first embodiment of the present invention, based on the width of the touch area (touch area) corresponding to the touch input to the bezel area, touch information corresponding to the touch input By blocking, when a user grips the mobile terminal 100, a touch malfunction caused by touching the bezel area of the touch screen can be prevented.

9 is a flowchart showing a control method of a mobile terminal 100 according to a second embodiment of the present invention.

First, the controller 180 determines whether a touch input to the bezel area 4-1 of the touch screen is received (S21). For example, the controller 180 determines whether a specific point (coordinate) of the bezel area 4-1 of the touch screen is touched by the user.

The controller 180 detects a minimum width (minimum width value) and a maximum width (maximum width value) of the touch area (touch area) corresponding to the touch input (S22).

The controller 180 determines (determines) whether the difference between the detected minimum width and maximum width is equal to or greater than the preset reference value (S23). The preset reference value is a reference value for determining whether or not the mobile terminal 100 is gripped by a user, and when the mobile terminal 100 is in a gripped state by the user, It may be a difference between a predetermined minimum width and a maximum width of the touch area (touch area) corresponding to the touch input to the bezel area 4-1. For example, assuming that the predetermined minimum width is 0.5 mm and the predetermined maximum width is 1 mm, the predetermined reference value may be 0.5 mm or more. The preset reference value may be changed by the user.

When the difference between the detected minimum width and maximum width is greater than or equal to a preset reference value, the controller 180 detects a speed from a touch start point to a touch end point corresponding to the touch input. For example, the controller 180 determines whether the mobile terminal 100 is in a gripped state by a user based on a speed from a touch start point to a touch end point corresponding to the touch input.

When the difference between the detected minimum width and the maximum width is greater than or equal to a preset reference value, the controller 180 determines (determins) whether the speed from the touch start point to the touch end point is less than a preset reference speed (S24). For example, the controller 180 determines (determines) whether the speed from the touch start point to the touch end point is less than 500 pixels/sec (preset reference speed). The preset reference speed may be changed by the user. That is, when the speed from the touch start point to the touch end point is less than 500 pixel/sec (pre-set reference speed), the controller 180 performs a drag operation while the mobile terminal 100 is gripped by the user. If the speed from the touch start point to the touch end point is 500 pixels/sec (pre-set reference speed) or higher, it is determined that the user intentionally performed the drag operation.

The controller 180 blocks the touch information corresponding to the touch input when the difference between the detected minimum width and maximum width is greater than a preset reference value and the speed from the touch start point to the touch end point is less than the preset reference speed. By doing so, malfunction of the touch screen is prevented (S25). That is, when a user grips (holds) the mobile terminal 100, a touch false operation caused by touching the bezel area of the touch screen is prevented.

When the difference between the detected minimum width and maximum width is less than the preset reference value, the controller 180 outputs touch information corresponding to the touch input (S26). For example, if the difference between the detected minimum width and maximum width is less than the preset reference value, the controller 180 outputs touch information corresponding to the touch input to the touch controller.

The controller 180 outputs touch information corresponding to the touch input when the difference between the detected minimum width and maximum width is greater than or equal to a preset reference value and the speed from the touch start point to the touch end point is greater than or equal to a preset reference speed. do.

Therefore, the control apparatus and method of the mobile terminal according to the second embodiment of the present invention, the width of the touch area (touch area) corresponding to the touch input to the bezel area and the speed from the touch start point to the touch end point By blocking the touch information corresponding to the touch input as a basis, it is possible to prevent a touch malfunction caused by touching the bezel area of the touch screen when the user grips the mobile terminal 100.

Hereinafter, a control apparatus and method of a mobile terminal according to a third embodiment of the present invention, which can prevent a touch malfunction caused by a specific area of the touch screen being touched when the user grips the mobile terminal 100 do.

10 is a flowchart showing a control method of a mobile terminal 100 according to a third embodiment of the present invention.

First, when the grip pattern setting mode is selected by the user, the controller 180 displays a grip pattern setting screen for setting the grip pattern on the display unit 151.

11 is an exemplary view showing a grip pattern setting mode according to a third embodiment of the present invention.

As illustrated in FIG. 11, when the grip pattern setting mode is selected by the user, the controller 180 sets a grip pattern including areas touched on the touch screen when the user grips the mobile terminal 100 ( In order to save), the information 11-1 requesting to grip the mobile terminal 100 a predetermined number of times (for example, 1 to 5 times or more) and the mobile terminal 100 are held and released. The video sample 11-2 is displayed (played) on the display unit 151. Therefore, the user can easily perform the grip pattern setting process while viewing the video sample 11-2.

The controller 180 sets the grip pattern through the grip pattern setting mode (S31).

12 is an exemplary view showing a grip pattern according to a third embodiment of the present invention.

As illustrated in FIG. 12, when the user grips the mobile terminal 100 in the grip pattern setting mode, the controller 180 sets the maximum width and the minimum width of the area(s) touched on the touch screen as the grip pattern. Set (recognize). For example, in the controller 180, a first bezel area (for example, a left bezel area) 12-3 of the touch screen is touched by a user's thumb, and a second bezel area of the touch screen When the (for example, the right bezel area) 12-4 is touched by at least one of the remaining fingers of the user, the first maximum width and the first area of the area touched in the first bezel area 12-3 1 Set the minimum width (touch information) and the second maximum width and the second minimum width (touch information) of the area(s) touched in the second bezel area 12-4 as the grip pattern 12-1 (Recognize). When the user grips the mobile terminal 100, the first bezel area may be single-touched, and the second bezel area may be multi-touched. That is, the controller 180 displays touch information (maximum width and minimum width) of a single region touched on the first bezel region and multi-region touch information (maximum widths and minimum widths) touched on the second bezel region. It is set as information of the grip pattern.

Here, according to a user's grip habit, the first bezel area may not be touched, only the second bezel area may be touched, the second bezel area may not be touched, and only the first bezel area may be touched. It might be. At this time, the controller 180 sets the maximum widths and minimum widths of the areas touched in the first bezel area (eg, the left bezel area) and/or the second bezel area of the touch screen as the grip pattern (recognition) )do.

The controller 180 displays the number of grips 12-2 each time the touch screen is gripped by the user in the grip pattern setting mode.

When the user draws the mobile terminal 100 by the preset number of times (for example, 5 times) in the grip pattern setting mode, the controller 180 assumes that the first bezel area is touched 5 times. Also, the maximum width range (for example, 1 mm to 1.5 mm or more) and the minimum width range (0.3 mm to less than 0.5 mm) of the five touched areas may be stored in the memory 160 as touch information.

When the user grips the mobile terminal 100 for the preset number of times (for example, 5 times) in the grip pattern setting mode, the control unit 180 causes the second bezel area to be 5 times by 3 fingers. Assuming that it has been touched, touch information of a maximum width range (for example, 1 mm to 1.5 mm or more) and a minimum width range (0.3 mm to less than 0.5 mm) of areas touched 5 times by the first finger among the three fingers Stored in the memory 160, and the maximum width range (for example, 1 mm to 1.5 mm or more) and the minimum width range (less than 0.3 mm to 0.5 mm) of the five touched areas by the second finger among the three fingers ) Is stored in the memory 160 as touch information, and a maximum width range (for example, 1 mm to 1.5 mm or more) and a minimum width range (0.3 mm) of the five touched areas by the third finger among the three fingers. ~0.5 mm or less) may be stored in the memory 160 as touch information. The controller 180 may set (recognize) touch information (maximum width range and minimum width range) stored in the memory 160 as touch information. The maximum width range and the minimum width range may vary according to a user's finger size.

The control unit 180 determines whether a touch input is received after setting the grip pattern in advance (S32). For example, the controller 180 determines whether a bezel area of the touch screen is touched by a user.

The controller 180 determines (determines) whether touch information (maximum width and minimum width or maximum width range and minimum width range) corresponding to the received touch input is the same as or similar to the grip pattern (S33).

When the touch information (maximum width and minimum width) corresponding to the received touch input is the same or similar to the grip pattern, the controller 180 effectively prevents a touch malfunction of the touch screen by blocking the touch information corresponding to the touch input. (S34). In the controller 180, the maximum width of the touch area corresponding to the received touch input belongs to the maximum width range corresponding to the grip pattern, and the minimum width of the touch area corresponding to the received touch input corresponds to the grip pattern. If it falls within the minimum width range, it is possible to prevent a touch malfunction of the touch screen by blocking touch information corresponding to the touch input.

If the touch information (maximum width and maximum width) corresponding to the received touch input is not the same or similar to the grip pattern, the controller 180 outputs touch information corresponding to the touch input (S35). For example, if the touch information (maximum width and maximum width) corresponding to the received touch input is different from the grip pattern, the controller 180 outputs touch information corresponding to the touch input to the touch controller. In the controller 180, the maximum width of the touch area corresponding to the received touch input does not fall within the maximum width range corresponding to the grip pattern, or the minimum width of the touch area corresponding to the received touch input corresponds to the grip pattern. If it does not fall within the minimum width range, touch information corresponding to the touch input may be output to the touch controller.

Therefore, in the control device and method of the mobile terminal according to the third embodiment of the present invention, the grip pattern for the touch screen is preset, and the maximum width and the minimum width of the touch area corresponding to the touch input are the grip pattern If it is the same or similar, by blocking the touch information corresponding to the touch input, it is possible to effectively prevent a touch malfunction caused by a specific area of the touch screen being touched when the user grips the mobile terminal 100.

Is set (recognized) as the grip pattern 14-3. For example, in the controller 180, a first bezel area (for example, a left bezel area) of the first touch screen 14-1 is touched by the thumb of the left hand of the user, and the second touch screen When the second bezel area of (14-2) (eg, the right bezel area) is touched by the user's right thumb, the maximum width and minimum width (or maximum width range and minimum width range) of the first bezel area and , Set (recognize) the maximum width and the minimum width (or the maximum width range and the minimum width range) of the areas touched in the second bezel area as the grip pattern 14-3. When the user grips the dual display of the mobile terminal 100, the first bezel area may be single-touched, and the two bezel areas may also be single-touched. That is, the controller 180 touch information (maximum width and minimum width) (or maximum width and minimum width range) of a single area touched on the first bezel area and touch information of a single area touched on the second bezel area. (Maximum width and minimum width) (or maximum width range and minimum width range) is set as information of the grip pattern 14-3.

When the user draws the mobile terminal 100 by the preset number of times (for example, 5 times) in the grip pattern setting mode, the controller 180 assumes that the first bezel area is touched 5 times. , The maximum widths and minimum widths (or maximum width range and minimum width range) of the five touched areas are stored in the memory 160 as touch information.

When the user draws the mobile terminal 100 by the preset number of times (for example, 5 times) in the grip pattern setting mode, the controller 180 assumes that the second bezel area is touched 5 times. , The maximum widths and minimum widths (or maximum width range and minimum width range) of the five touched areas are stored in the memory 160 as touch information. The controller 180 sets (recognizes) touch information (maximum widths and minimum widths (or maximum width ranges and minimum width ranges)) stored in the memory 160 as the grip pattern.

The control unit 180 determines whether a touch input is received after setting the grip pattern in advance (S42). For example, the controller 180 determines whether a bezel area of the touch screen is touched by a user.

The controller 180 determines (determines) whether touch information (maximum width and minimum width) (or maximum width range and minimum width range) corresponding to the received touch input is the same as or similar to the grip pattern (S43).
