3 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 3, when a pointer such as a user's finger or a pen approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

In FIG. 3, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a touch touch. When the pointer is positioned below the distance d ₁ on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d ₁ or more and less than d ₂ on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the distance d ₂ or more and less than d ₃ on the touch screen, the pointer is recognized as a proximity touch of a third proximity depth. When the pointer is positioned at a distance of more than d ₃ from the touch screen, the proximity touch is recognized as released.

Accordingly, the controller 180 may recognize the proximity touch as various input signals according to the proximity depth and the proximity position of the pointer, and perform various operation control according to the various input signals.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal will be described with reference to the accompanying drawings.

4 is a flowchart illustrating a control process of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 4, the controller 180 of the mobile terminal 100 displays a screen including at least one UI object provided with a menu function on the touch screen 151 [S111]. It is checked whether an area for changing the display position of the screen is designated [S112].

If an area to change the display position of the screen is designated on the touch screen 151 [S113], the controller 180 reduces and displays the screen in the designated area [S114].

In this case, among the UI objects included in the screen may include a UI object for the command to change the position of the screen, the controller 180 has an area to change the position of the screen after the screen position change UI object is selected from the user If specified, the designated area is recognized as an area to be repositioned on the screen.

That is, when a user drags and touches a boundary point of an area to change the position of the screen on the touch screen 151, the controller 180 recognizes the area touched and dragged by the user as an area to change the position of the screen. The screen may be reduced and displayed in the touched area.

In addition, after the user touches the touch screen 151 to fill a horizontal line and a vertical line, and touches any one of the first to fourth quadrants in the horizontal line and the vertical line, the touched quadrant The screen may be reduced in size. In this case, the touch operation of the user may be a touch touch or a proximity touch. That is, the user may designate an area to change the position of the screen by directly touching and touching the touch screen 151, and designate an area to be repositioned by touching the proximity sensor 141 of the touch screen 151. It may be.

In the meantime, when the screen is reduced in the designated area in step S113, the UI objects included in the screen may be reduced in size. In this case, when the UI objects are reduced in size, since the user does not easily touch the UI objects in the reduced screen, the controller 180 may allow the user to easily touch the UI objects in the reduced screen. UI objects on the screen can be displayed in their original size without being scaled down.

In addition, when the screen 180 is touched by a user in a state in which the screen is reduced within the designated area in operation S113, the controller 180 makes it easy for the user to touch the UI objects at the touched point.
