Description

Folding type multifunction display device {APPARATUS FOR MULTIFUNCTIONAL DISPLAY OF FOLDING TYPE}

The present invention relates to a folding type multifunction display device.

Portable personal terminal devices are very diverse, such as notebook computers, personal multimedia players (PMPs), car navigation systems, portable music players (MP3Ps), mobile phones, and the like. Since all these devices are cumbersome to carry, recent attempts have been made to fuse each device to have two or more functions. That is, one device can replace various portable personal terminal devices with a device having multiple functions. It is to increase the portability.

However, although the portability may be increased through a device in which various functions are fused (hereinafter, the fusion device), the functionality of the screen display device may be too small if the fusion device is made too small in consideration of the portability. There is a disadvantage to be limited. When a terminal provides various functions, the required specifications (screen size, device size, computing power, power consumption, etc.) are all different depending on the operation of each function.

In the prior art, attempts have been made, for example, to incorporate a vehicle navigation function into a mobile phone or to combine a mobile phone function into a PMP in order to combine terminals having various functions into one.

However, these attempts have the following problems.

First, existing fusion devices have characteristics that are not compatible with various functionalities and high portability. In general, portable phones are small in size and easy to carry around (high portability), but due to their size constraints, the screen is too small and degrades in performance (low functionality). On the other hand, notebook computers or PMPs are more versatile and perform better than mobile phones (high functionality), but they are too large for mobile phones, making them inconvenient for everyday use (low portability). Therefore, each portable personal device focuses on one characteristic of functionality or portability, and it is difficult to satisfy both conditions at the same time.

Secondly, the existing fusion device is inconvenient in use. Existing convergence devices have been cumbersome such as turning on a separate switch, changing a setting in an internal menu, or attaching a separate device to switch from one function to another.

As a representative example of the existing fusion device having such problems, there is a device that combines a vehicle navigation with a mobile phone. Mobile phones equipped with car navigation has a hassle to purchase a navigation cradle separately and to be mounted on the vehicle. Even with such a hassle, the small screen of the mobile phone is too inconvenient to use while driving a vehicle and receiving directions.

An object of the present invention for solving this problem is to provide a display device that can satisfy the portability and functionality of the terminal at the same time.

Folding type multi-function display device according to the present invention has a plurality of unit display panel that can be independently on / off, the display panel unit of the touch screen input method consisting of a foldable material, the number of times or the folded position of the display panel unit Power is supplied to the operation unit, the display panel unit, and the operation unit that operate the hardware and the software required to execute the preset application to execute the preset application, and the unit is set according to the number of times the display panel unit is folded or the folded position of the display unit.

In addition, when the display panel unit 100 in which the eight unit display panels are turned on is folded in half (two times in total), as shown in FIG. 2C, four of the unit display panels in the on state are The image may be displayed through the four unit display panels that are turned on while the other four are turned off and remain on.

In addition, the display panel unit 100 may partially turn on / off a plurality of unit display panels according to the folded position. For example, even if the display panel 100 is folded once, the on / off state of the unit display panel is changed depending on whether 1/2 of the area of the display panel 100 is folded or 1/4 is folded. Accordingly, the unit display panels to be turned on / off may be different even if the same number of times are folded depending on which part of the unit display panel is folded and which part of the unit display panel is folded. In addition, the display panel unit 100 may partially turn on / off the plurality of unit display panels according to a combination of the number of times of folding and the folded position.

The power supply unit 120 supplies power to the display panel unit 100 and the operation unit 110. More specifically, the power supply unit 120 supplies only power necessary for the operation of the display panel 100 and the operation unit 110.

For example, as shown in FIG. 3, the power supply unit 120 is connected to each of the plurality of unit display panels, and thus the unit display is preset according to the number of times or the folded position of the display panel unit 100 among the plurality of unit display panels. Power may be supplied to the display panel unit 100 so that the panel is turned on. That is, when the display panel unit 100 is folded, the controller 140 recognizes the number of times the display panel unit 100 is folded and outputs a control signal to the power supply unit 120 according to the number of times the display panel unit 100 is folded. The power supply unit 120 supplies power only to the unit display panel set according to the control signal received from the control unit 140. For example, when the display panel unit 100 is folded n times, the power supply unit 120 receives a control signal having a predetermined level set according to the folding of the display panel unit n from the control unit 140 and inputs the control signal. Power may be supplied to the corresponding unit display panel set according to the level of the control signal. That is, which unit display panel of the plurality of unit display panels is turned on or off according to the level of the control signal. Accordingly, the power supply unit 120 displays a plurality of unit displays according to the number of times the display panel unit 100 is folded. The panel will be partially powered on and off.

In addition, the power supply unit 120 may supply power to the unit display panels set according to the folded position of the display panel unit 100. That is, the unit display panel to be turned on / off is set according to which part of the unit display panel is folded, thereby supplying power to the set unit display panel.

In addition, the display panel unit 100 may partially turn on / off the plurality of unit display panels according to a combination of the number of times of folding and the folded position.

<Detection part>

The sensing unit 130 may be installed on an axis in which the display panel unit 100 is folded. In addition, the sensing unit 130 may include a plurality of unit sensing units Sn that detect the folding of the display panel unit 100 using an inductive coupling communication method. The plurality of unit detectors Sn detects the folds of the display panel 100 and outputs a detection signal to the controller 140.

Each of the plurality of unit detection units Sn corresponds to the first unit detection units 101-a and 103-a installed at one side about the folding axis and the first unit detection units 101-a and 103-a at the other side. The second unit detectors 101-b and 103-b and the comparison unit 105 are installed.

The first unit detectors 101-a and 103-a include a first inductor 103-a and an inductive transmitter 101-a. The inductive transmitter 101-a is connected to the first inductor 103-a and transmits data.

The second unit detectors 101-b and 103-b include a second inductor 103-b and an inductive receiver 101-b. The inductive receiver 101-b is connected to the second inductor 103-b and receives data transmitted from the inductive transmitter 101-a through the second inductor 103-b.

The comparator 105 compares the received signal received by the inductive receiver 101-b with the reference signal Vref, and outputs a detection signal to the controller 140 when the received signal is large.

<Control part>

The control unit 140 receives the detection signal output from the sensing unit 130, determines the number of times or the folded position of the display panel unit 100, and operates the operation unit 110 and the power supply unit 120 according to the determination result. To control.

For example, when the control unit 140 operates according to the number of times the display panel unit 100 is folded, the control unit 140 receives the detection signals output from the unit detection units Sn and receives the input detection signals. The final number of inputs may be determined, and the operation of the operation unit 110 and the power supply unit 120 may be controlled according to the determination result. When the control unit 140 operates according to the folded position of the display panel unit 100, the control unit 140 is set according to the position of the unit detecting unit Sn in which a detection signal is output among the plurality of unit detecting units Sn. The operation of the operation unit 110 and the power supply unit 120 may be controlled. In addition, the control unit 140 may control the operation of the operation unit 110 and the power supply unit 120 to be performed by using the combined information about the number of times or the folded position of the display panel unit 100.

2. Example of operation

5 and 6 will be described in detail the operation of the folding multi-function display device according to an embodiment of the present invention.

5 is a diagram illustrating a process of switching a function according to an operation and a folding count of the folding type multifunction display device according to an exemplary embodiment of the present invention. 6 is a diagram illustrating an example of an application performed according to the number of times of folding of a folding multifunction display device according to an exemplary embodiment of the present invention.

First, as shown in (a) of FIG. 5, it is assumed that the display panel 100-a has a size of about A4 paper and is unfolded and unfolded.

First, the display panel unit 100-a in FIG. 5A may be used as a notebook computer of a screen touch input method illustrated in FIG. 6A.

Next, when the display panel unit 100-a is folded in half as in step (a) ', the folding is detected and automatically switched to the preset application according to the current number of folding (① folding). At this time, the display panel unit 100-b folded once is 1/2 of the size of the display panel unit 100-a in the step (a), and the display device is shown in FIG. 6B in the notebook computer shown in FIG. 6A. The application is automatically switched for use with the illustrated car navigation.

Next, when the display panel unit 100-b is folded in half as in step (b) ', the folding is detected, and the display panel unit 100-b is automatically switched to a preset application according to the number of times of folding (② folding). At this time, the display panel unit 100-c folded twice is one-fourth the size of the display panel unit 100-a in step (a), and the display device is shown in FIG. 6C in the vehicle navigation shown in FIG. 6B. The application automatically switches over to the PMP shown.

Next, when the display panel unit 100-c is folded in half, the folding is detected, and the display panel unit 100-c is automatically switched to the preset application according to the current folding number (③ folding). At this time, the display panel portion 100-d folded three times is 1/8 of the size of the display panel portion 100-a in the step (a), and the display device is shown in FIG. 6D in the PMP shown in FIG. 6C.

For example, when operating the display device as a mobile phone, it is possible to minimize the power consumption instead of reducing the area in which the screen is displayed, compared to when operating the notebook computer.

In addition, when switching the function of the display device, it is possible to minimize the waste of resources such as power and computing power by activating only hardware and software specific to each function.

In addition, switching between various devices can be easily changed by simply folding and unfolding, thereby minimizing the inconvenience in use.

In addition, it minimizes the hassle of carrying a variety of portable personal terminal devices, and can be used more easily through intuitive switching between functions.
