Abstract

A mobile device for operating displayed content having a dual touch screen based on a transparent display panel is provided. The mobile device allows a method for operating displayed content in response to a touch event using at least one of front and back faces of the dual touch screen. The mobile device displays the content on the transparent display panel with a predefined brightness. When receiving a touch event through the transparent display panel, the mobile device modifies the brightness of parts or whole of the displayed content in response to the touch event.

Claims

1. A method for operating displayed content in a mobile device having a transparent display panel, the method comprising:

displaying the content on the transparent display panel with a predefined brightness;

receiving a touch event through the transparent display panel; and

modifying the brightness of parts or whole of the displayed content in response to the touch event.

2. The method of claim 1, wherein the displaying of the content includes:

representing one of transparent content with the predefined brightness in order to allow a background to be seen, non-transparent content on the entire screen, and both transparent content and non-transparent content in order to allow the background to be partially seen.

3. The method of claim 2, wherein the receiving of the touch event includes:

receiving one of a front touch event, a back touch event and a double-sided touch event through at least one of the front and back sides of a display unit.

4. The method of claim 3, wherein the representing includes:

performing one of a transparentizing process by modifying the brightness of a specific region corresponding to the touch event in the displayed content; and

a transparentizing process by modifying the brightness of all regions except the specific region corresponding to the touch event in the displayed content.

5. The method of claim 3, wherein the representing includes:

cutting a specific region selected by the touch event; and

performing a transparentizing process by modifying the brightness of the cut region in the content.

6. The method of claim 3, wherein the representing includes:

performing one of a transparentizing process by modifying the brightness of two or more specific regions selected by the touch event; and

a transparentizing process by modifying the brightness of all regions except the two or more specific regions selected by the touch event in the displayed content.

7. The method of claim 3, wherein the representing includes:

creating and representing content in response to the first touch event; and

performing a transparentizing process by modifying the brightness of parts or whole of the created content in response to the second touch event.

8. The method of claim 7, wherein the created content is drawn or inputted and is different from the displayed content, depending on the predefined brightness.

9. A mobile device comprising:

a touch screen for receiving a touch event and then for modifying the brightness of content in response to the touch event; and

a control unit for determining the type of the touch event received from the touch screen and then, in response to the touch event, for performing a transparentizing process by modifying the brightness of parts or whole of the content displayed on the touch screen.

10. The mobile device of claim 9, wherein the touch screen includes:

a display unit for displaying the content modified in response to the touch event;

a front touch sensor disposed on the front side of the display unit and for receiving the touch event; and

a back touch sensor disposed on the back side of the display unit and for receiving the touch event.

11. The mobile device of claim 10, wherein the touch event includes:

a front touch event detected by the front touch sensor;

a back touch event detected by the back touch sensor; and

a double-sided touch event detected by both the front and back touch sensors.

12. The mobile device of claim 10, wherein the control unit modifies the brightness of parts or whole of the displayed content in response to the front touch event, the back touch event or the double-sided touch event.

13. The mobile device of claim 12, wherein the control unit performs a transparentizing process by modifying the brightness of at least one specific region corresponding to the touch event in the displayed content, by modifying the brightness of all regions except the at least one specific region corresponding to the touch event in the displayed content, or by modifying the brightness of a specific region selected by the touch event and cut in the displayed content.

14. The mobile device of claim 12, wherein the control unit creates and represents content in response to the first touch event, and performs a transparentizing process by modifying the brightness of parts or whole of the created content in response to the second touch event.

15. The mobile device of claim 11, wherein the control unit includes:

a touch region check unit for identifying a specific region on which the touch event is inputted, by finding coordinates of a touched region from a touch signal received from at least one of the front and second touch sensors; and

a brightness modification unit for increasing or decreasing the brightness of the displayed content according to predefined levels of the touch event identified by the touch region check unit.
