In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.
For the sake of convenience of explanation, the act of recognizing that an object is located on the touch screen while the object is not in contact with the touch screen is referred to as "proximity touch" Quot; contact touch ". The position at which an object is touched on the touch screen means a position at which the object corresponds vertically to the touch screen when the object is touched.

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 by 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 when 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.

More specifically, a photosensor mounts a photo diode and a transistor (TR) in a row / column and scans the contents placed on the photosensor using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor performs the coordinate calculation of the object to be sensed according to the amount of change of light, and the position information of the object to be sensed can be obtained through the calculation.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
FIG. 2 is a flowchart illustrating a control method of the mobile terminal 100 according to an exemplary embodiment of the present invention.
First, the mobile terminal 100 can start a video call according to a wireless signal transmitted / received to / from another terminal (S210). Specifically, the mobile communication unit 112 can transmit / receive a radio signal to / from another terminal (not shown). When a video call according to the wireless signal is started, the mobile terminal 100 can display a plurality of call screens on the touch screen 151 (S220). Each of the plurality of call screens may indicate that a user participating in the video call is displayed. As it is widely known, a detailed description will be omitted.
Thereafter, the mobile terminal 100 may determine whether there is a predetermined input in order to deactivate the touch screen 151 (S230).
If it is determined that there is a preset input (S230_Y), the mobile terminal 100 may disable the touch input to the touch screen 151 (S240). In this case, the mobile terminal 100 can still display a plurality of call screens. That is, the user can continue the video call but may not be able to touch input through the touch screen 151.
Here, deactivation of touch input does not mean deactivation of all touch inputs. That is, even if the touch input is inactivated, the mobile terminal 100 can maintain the activation of the touch input for activating the touch screen 151 as a whole, and deactivate the touch input.
Accordingly, the mobile terminal 100 may determine whether there is a preset input to activate the touch screen 151 (S250).
If it is determined that there is a predetermined input (S250_Y), the mobile terminal 100 can activate the touch input to the touch screen 151 (S260). That is, the user can continue the video call and can also perform touch input through the touch screen 151. On the other hand, if it is determined that there is no preset input (S250_N), the mobile terminal 100 can maintain inactivation of the touch input to the touch screen 151 (S240).
Accordingly, unintentional touch input can be prevented by deactivating the touch screen 151 during a video call. In the case where a touch input is required, an input for activating the touch screen 151 is performed to enable the intended touch input .
Meanwhile, if it is determined that there is no preset input for deactivating the touch screen 151 during a video call (S230_N), the mobile terminal 100 can maintain the activation of the touch input to the touch screen 151 (S270) . In this case, the mobile terminal 100 can still display a plurality of call screens. That is, the user can continue the video call and can also touch input through the touch screen 151.
FIGS. 3 to 8 illustrate examples of touch input deactivation and activation of the mobile terminal 100 according to an exemplary embodiment of the present invention. Hereinafter, the description of the parts overlapping with the above description will be omitted.

In addition, The lock message 136 may be a message informing the user that the touch input is inactivated, such as text. In this case, the lock message 136 may disappear after a predetermined time has elapsed.
Therefore, when the lock button 134 is selected, a screen as shown in FIG. 5 (b) can finally be displayed. That is, since the status bar 133 and the plurality of menus 133-1 through 133-3 disappear, the touch input can be deactivated. In this case, the lock message 136 shown in Fig. 5 (a) is not displayed, and the screen shown in Fig. 5 (b) may be displayed immediately.
In FIGS. 3 to 5, description has been given of the case where the touch input is inactivated. Therefore, the case where the touch input is activated will be described with reference to FIGS. 6 to 8. FIG.
It is noted that the deactivation for the touch input does not mean deactivation for all the touch inputs. That is, since the status bar 133 and the plurality of menus 133-1 through 133-3 are disappeared, the touch input to the status bar 133 can be inactivated. The status bar 133 and the plurality of menus 133- 1 to 133-3) may be displayed again for a touch input. This will be described in detail below.
FIG. 6 illustrates a case where a video call is made in a state in which the touch input is inactivated, and the user can touch at least one of the first screen 131 and the second screen 132. FIG.

In this case, as shown in Fig. 7, a release button 135 may be displayed in one area of the touch screen 151. [ The position at which the release button 135 is displayed may be the same as the display position of the lock button 134 as described above.
Further, when the release button 135 is selected, the touch input to the touch screen 151 can be activated. That is, when the release button 135 is selected, the video call is maintained and the touch input to the touch screen 151 can also be activated. Therefore, the lock button 134 may be referred to as an activation button.
8 illustrates the touch screen 151 when the release button 135 is selected. Referring to FIG. 8, when the release button 135 is selected, the release button 135 can be changed to the lock button 134 and displayed. In this case, the lock button 134 may be the same shape as the release button 135, but it may be a different shape, and the shape may be the same but only the color may be different.
Accordingly, when the user desires to deactivate the touch input to the touch screen 151 again, the user can select the lock button 134, which is described with reference to FIGS.
Also, since the video call is maintained, each user can be displayed on the first screen 131 and the second screen 132.
In addition, a release message 137 may be displayed in one area of the touch screen 151. [ The release message 137 may be a message informing the user that the touch input is activated by text or the like. In this case, the release message 137 may disappear after a predetermined time has elapsed.
