In addition, the battery 191 may be configured to enable wireless charging through a wireless charger. The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

On the other hand, in this drawing, the rear cover 103 is coupled to the rear case 102 so as to cover the battery 191 to limit the separation of the battery 191, and to protect the battery 191 from external shock and foreign substances. It is illustrated. When the battery 191 is configured to be detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

Referring back to FIGS. 1 and 2, each display includes a display panel and a touch sensor, which are direct components that perform screen output. The display panel can be implemented in a manner such as LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode), Micro-LED, etc., depending on the screen output method, and in the case of the LCD method, a backlight unit (BLU) is included. It means a combination of a plurality of panels. The touch sensor senses a touch input to an output area formed by the display panel, and thus may be provided corresponding to the display panel. As described in FIG. 3, the touch sensor may be provided in the form of a touch screen. In this case, the touch sensor may be provided on the upper surface of the display panel or at any position between a plurality of panels of the display panel.

The first display 151 includes a first display panel 151D and a first touch sensor 151T, and the second display 261 includes a second display panel 261D and a second touch sensor 261T. do. The first touch sensor 151T is provided to correspond to the output area of the first display panel 151D, and the second touch sensor 261T is provided to correspond to the output area of the second display panel 261D. As described above, the first display panel 151D and the first touch sensor 151T are provided on the first body 100, and the second display panel 261D and the second touch sensor 261T are It is provided in 260. The first body 100 and the second body 260 are coupled to each other so that the first display panel 151D and the second display panel 261D are connected and output, and the first touch sensor 151T or the second touch sensor ( The input to 261T) may affect the output of the first display 151 or the second display 261.

5 is a conceptual diagram of a terminal set 10 related to the present invention.

The power supply unit 190 supplies power to the first display panel 151D, the first touch sensor 151T, the second display panel 261D, and the second touch sensor 261T under the control of the controller 180. . The controller 180 may cut off the power supply to each component as necessary. For details on the operation between the controller 180, the

display panels

151D and 261D, and the

touch sensors

151T and 261T, the same principle mentioned in FIG. 3 is applied. In addition, the operation of the

display panels

151D and 261D and the

touch sensors

151T and 261T, which will be described later, may be understood to be driven by the configuration itself or the control of the controller 180 unless a separate subject is described. .

6 shows an example of a terminal set 10 related to the present invention.

In the dual display type including the first display 151 and the second display 261, the second display 261 often functions only as an output area. For example, a game application is executed and output across the first display 151 and the second display 261, but the controller of the game is output and functioned on the first display 151, and the second display 261 A game screen in progress may be displayed. As another example, the first display 151 is placed on the floor or held by a hand to receive a touch keyboard input, and the second display 261 is a message application reflecting the result of such input, a web browser application, etc. I can. In addition, even when a separate application that is not related to each other between the first display 151 and the second display 261 is being executed and output, content with a little user's touch input such as video output may be output on the second display 261. Most likely.

Nevertheless, each of the first display 151 and the second display 261 is provided with a touch sensor, and power is supplied to maintain a state in which a touch input can be always received while the display is driving. From the viewpoint as described above, driving of the touch sensor unnecessarily consumes power.

Accordingly, in the present invention, when a specific condition occurs, power supply to the touch sensor is blocked so that the touch sensor no longer performs sensing of the touch input. More specifically, when a predetermined specific condition is satisfied, the controller generates a touch input deactivation signal, and causes the power supply unit to cut off the power supply to the touch sensor according to the touch input deactivation signal.

Below, examples of specific conditions for generating a touch input deactivation signal will be described. In the above-described examples, since it has been described that the frequency of use of the touch sensor of the second display 261 is low, it is assumed that the touch input deactivation operates on the second touch sensor. However, this is to prevent duplication of descriptions, so the operations may be reversed.

[Example 1]

7 and 8 show output areas of the terminal set 10 related to the present invention, respectively, and FIG. 9 shows that the terminal set 10 related to the present invention lies on the bottom surface 410.

The touch input deactivation signal may be generated when a touch input does not occur in the output area of the second display panel 261D, more precisely, in the second touch sensor 261T corresponding to the output area for more than a preset time.

If the touch input does not occur in the second touch sensor 261T for more than a preset time, the touch input is unlikely to occur in the future, and thus the touch input can be deactivated.

This preset time may be set in advance by user selection. FIG. 7 shows a screen 310 for setting a time condition for a user to start deactivating a touch input. Alternatively, it may be specified by a time set in the system without a separate setting from the user.

However, since deactivation of the touch input due to the lapse of a preset time may provide unintended discomfort to the user, the controller may output an indicator 321 indicating that the power supply to the touch sensor has been cut off, as shown in FIG. 8. .

At the same time, the control unit may output a menu 322 capable of resuming the cut off power supply. This menu is preferably output to an output area formed by the first display panel 151D in which the touch input is activated. Alternatively, the controller may control to resume the cut-off power supply when an application that has been output to the output area formed by the second display panel 261D is terminated. That is, the cutoff of power supply to the touch sensor may be maintained until the application being executed at the time is terminated.

Additionally, the angle of the first display panel 151D or the second display panel 261D may be considered as a condition for generating the touch input deactivation signal. For example, a condition in which the first body with the first display panel 151D is parallel to the floor surface and the second body with the second display panel 261D is rotated by a certain angle A from the floor surface is additionally applied. Can be added. This is based on the fact that in the use of dual displays, there are more touch inputs to the display panel on the floor surface than to the display panel on the floor surface.

The features mentioned in the present embodiment may be equally applied to other embodiments described later within a range not contradictory. Therefore, the same features are not separately mentioned in order to prevent duplication of description.

Furthermore, the present embodiment may be applied in combination with the embodiments described later.

[Example 2]

Embodiment 2 presents an example of cutting off power supply to a second touch sensor based on characteristics of an executed and output application.

[Example 2-1]

10 shows an embodiment of a terminal set 10 related to the present invention.

The touch input deactivation signal outputs the controller 3311 to the output area of the first display panel 151D, and the content 3312 operated by the controller 3311 to the output area of the second display panel 261D. This may occur when the application 331 that outputs is running.

As described above, when an application separately provided with the controller 3311 is executed, a direct touch input to the output area of the second display panel 261D on which the operated content 3312 is output is unnecessary. The touch sensor 261T may be deactivated.

As an additional measure for minimizing power consumption, the controller may lower the output performance of the first display panel 151D that outputs the controller 3311. This is because the controller 3311 has simple information to be displayed and does not change rapidly or frequently. As a first method, the resolution output from the first display panel 151D may be lowered. In addition, by activating the upscale function of the drive IC, it is possible to prevent the lowered resolution from being greatly emphasized. As a second option, you can turn off the image enhancement engine. As a third method, the output scan rate of the first display panel 151D may be lowered. For example, the frame rate can be lowered from 60fps to 30fps.

[Example 2-2]

The touch input deactivation signal may be generated when a game application supporting auto play is running (not shown). When an automatic play command of a game application supporting automatic play is input, the controller may trigger the input to generate a touch input deactivation signal.

[Example 2-3]

11 shows an embodiment of a terminal set 10 related to the present invention.

Alternatively, the touch input deactivation signal may be generated when an application 332 that continuously outputs an image of a relatively long time such as a movie is running. When the image output of the image output application 332 starts, the controller may generate a touch input deactivation signal by triggering it.

[Example 3]

Alternatively, the touch input deactivation signal may be generated by a user input. That is, a menu corresponding to a touch input deactivation may be output, and may be generated when a user input for the corresponding menu is generated. This can be effective in that the user intention is clearly reflected. When the second touch sensor is deactivated, a deactivation input menu may be input through a corresponding second touch sensor, and an input menu for reactivation may be output on the first display panel. Alternatively, all input menus for deactivation or activation of the second touch sensor may be output to the first display panel.

The touch input deactivation signal may be generated not by a touch input to a corresponding menu, but by a time of flight (TOF), a palm approach input using a roughness sensor, or a multi finger input.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.

The above-described features can be partially or wholly applied to the terminal set and control method thereof related to the present invention.
