Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

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 proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting unit may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, a battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 due to an external force, taking into account the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

Meanwhile, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly grasps and uses. These wearable devices include smart watch, smart glass, and head mounted display (HMD). Hereinafter, examples of a mobile terminal extended to a wearable device will be described.

The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device. For example, when a telephone is received in the mobile terminal 100, it is possible to perform a telephone conversation via the wearable device or to confirm the received message via the wearable device when a message is received in the mobile terminal 100 .

Referring to (c) of FIG. 17, the mobile terminal can output the game application as background content. In an embodiment of the present invention, the mobile terminal may output the third virtual home button 1730 in an area where a button for receiving a control command on the area of the output game application is not output.

18 is a view for explaining colors of a virtual home button corresponding to background contents according to an embodiment of the present invention. Hereinafter, in the embodiment of FIG. 18, the description overlapping with FIGS. 4, 16 and 17 will be omitted.

18 (a) and 18 (b), the mobile terminal can change the color of the virtual home button corresponding to the outputted background content and output it. In one embodiment of the present invention, the mobile terminal may output the home screen as background content. With the background content being output, the mobile terminal can output the virtual home button 1810. The mobile terminal can change the color of the virtual home button 1810 according to the output background content.

Referring to FIG. 18A, when the background content color is white, the mobile terminal can output the color of the virtual home button 1810 in black. On the other hand, referring to FIG. 18B, when the background content color is black, the mobile terminal can output the color of the virtual home button 1810 in white. That is, the mobile terminal may output a virtual home button 1810 of a color forming a complementary color of background content.

The user can freely change the color of the background content. Accordingly, the mobile terminal outputs the virtual home button 1810 having the complementary color of the background content color to clearly distinguish the background content from the virtual home button 1810 can do.

19 is a flowchart illustrating a method for changing a virtual home button to a fingerprint recognition button according to an embodiment of the present invention. 19 described below can be controlled by the control unit 180 of the mobile terminal shown in FIG. 1A. In the embodiment of FIG. 19, the description overlapping with FIG. 4 will be omitted.

In step S1910, the mobile terminal can output background content on the display unit. Here, the background content may include a lock screen, a home screen, various application contents, and the like. In a state in which the background content is output, the mobile terminal can output the virtual home button. Here, the mobile terminal can output the lock screen as background content.

In step S1920, the mobile terminal may sense an input signal to the virtual home button. Here, the input signal may correspond to a predetermined touch input signal. For example, the predetermined touch input signal may include a long touch and a deep-press touch. Here, the long touch may correspond to a touch input signal over a predetermined time, and the deep press touch may correspond to a touch input signal corresponding to at least one of an area and a pressure sensed from the touch input. For example, the user can touch and hold the virtual home button.

In step S1930, when the mobile terminal senses the input signal for the virtual home button, the mobile terminal may change the virtual home button to the fingerprint recognition button and output the virtual home button. Here, the fingerprint recognition button may correspond to a button for inputting a fingerprint from the user. In one embodiment of the present invention, the mobile terminal can release the locked state of the mobile terminal by sensing the fingerprint input to the fingerprint recognition button, with the lock screen being output.

20 is a flowchart illustrating an embodiment of moving a virtual home button according to an embodiment of the present invention. 20 described below can be controlled by the control unit 180 of the mobile terminal shown in FIG. 1A. In the embodiment of FIG. 20, the description overlapping with FIGS. 4 and 19 is omitted.

In step S2010, the mobile terminal may output background content including an icon. In a state in which the background content is output, the mobile terminal can output a virtual home button to an area where no icon is displayed on the display unit.

In step S2020, the mobile terminal may sense a first input signal that moves the position of the virtual home button to an area corresponding to the icon. Here, the first input signal may correspond to a signal for drag-and-touch inputting the virtual home button to an area corresponding to the icon while touching the virtual home button.

In step S2030, the mobile terminal can determine whether or not the additional function for the icon is mapped. If the mobile terminal is mapped with an additional function for the icon, step S2040 may be performed, and if the additional function for the icon is not mapped, step S2060 may be performed. Here, the additional function can correspond to content other than the content to be output when the icon is touched and executed.

In step S2040, if the additional function for the icon is mapped, the mobile terminal can overlay the virtual home button on the icon according to the first input signal.

In step S2050, with the virtual home button overlaid on the icon, the mobile terminal may sense a second input signal for the icon. Here, the second input signal may correspond to a signal for touching the virtual home button and the icon together. For example, the second input signal may correspond to a signal for touching the virtual home button for a long time in a state in which the virtual home button is overlaid on the icon. In one embodiment of the present invention, when the mobile terminal senses a second input signal for an icon, it may perform additional functions mapped to the icon.

In step S2060, if the additional function for the icon is not mapped, the mobile terminal may move the virtual home button to an adjacent position of the icon according to the first input signal. Here, the adjacent position of the icon may correspond to an area within the predetermined range from the icon, where no other icon exists. In addition, the adjacent positions of the icons may be at least one. Although not shown in the drawing, when the adjacent position of the icon is a plurality of areas, the mobile terminal can select an area located closest to the icon as an adjacent position.

Accordingly, the user can release the lock screen without touching the mobile terminal while holding the mobile terminal in one hand, and can use the content through the home screen.
