Abstract

A mobile terminal and a method of controlling an image display thereof are disclosed. A display module for a mobile terminal as disclosed herein may include a display for displaying an image that includes one or more objects, a user input interface to receive an input to change the image between a 2D display and a 3D display, and a controller configured to change the displayed image between the 2D display and the 3D display based on the received input. The controller may control the display to sequentially display one or more intermediate images in order to gradually change an extent in which at least one of the one or more objects is perceived to protrude or recede into the display during the change in the displayed image.

13. The display module of claim 1, wherein the controller controls a number of the intermediate images to be displayed during the change in the displayed image and the extent in which the at least one object in each of the intermediate images protrudes or recedes.

14. The display module of claim 1, wherein the display includes a touchscreen configured to receive a touch input at a first point of the displayed image, and wherein the controller is configured to define a first region of the displayed image that includes the first point and to change the display of the image in the first region to be gradually recessed.

15. The display module of claim 14, wherein the touch input is a selection of the at least one of the one or more objects, and the first region includes the at least one of the objects.

16. The display module of claim 14, wherein the image in the first region includes a plurality of pixels, and wherein the controller controls an extent in which the plurality of pixels are recessed such that the extent of recess of each pixel is reduced with increased distance from the first point.

17. The display module of claim 14, wherein the controller defines a second region that surrounds the first region, the image in the second region displayed to gradually protrude corresponding to the extent in which the image in the first region is recessed.

18. The display module of claim 17, wherein the image in the second region includes a plurality of pixels, and wherein the controller controls an extent in which the plurality of pixels in the second region protrudes such that the extent of protrusion of each pixel is reduced with increased distance from the first region.

19. The display module of claim 14, wherein, if the touch input is removed from the first point, the image displayed in the first region is restored to a state prior to the touch input.

20. The display module of claim 14, wherein, if the touch input at the first point is a touch &

drag input in a first direction, the first region is moved in the first direction corresponding to a movement of the touch &

drag input.

21. The display module of claim 20, wherein, during the movement of the touch input, a first distance between a position of the touch input and a leading edge of the first region is less than a second distance between the position of the touch input and a trailing edge of the first region, the leading edge positioned in the direction of the movement and the trailing edge positioned opposite the direction of the movement, and wherein

the image in the first region adjacent to the leading edge is recessed at a first angle and the image in the first region adjacent to the trailing edge is recessed at a second angle, the first and second angles corresponding to the first and second distances.

22. The display module of claim 21, wherein the image displayed at the first point is gradually restored to a previous state as the first region is moved away from the first point.
