Abstract

Provided is a method of displaying a user interface of a portable terminal having a two-sided touch screen where a first touch sensor and a second touch sensor are formed to the front side and the backside of a display unit. The method includes displaying a user interface including at least one of a background screen and at least one or more contents in the display unit. The method also includes changing brightness of the user interface according to a detected state of the portable terminal based on a touch event.

Claims

1. A method, comprising:

displaying a user interface comprising a background and a content to a display unit; and

changing brightness of the user interface according to a touch and/or a tilt event to a portable terminal, wherein the portable terminal comprise two-sided touch screen comprising a first touch sensor and a second touch sensor formed the respective side of the portable terminal.

2. The method of claim 1, further comprising:

determining a touch event from the two-sided touch screen via the first touch sensor or the second touch sensor; and

changing brightness of the user interface and displaying the user interface according to the determined touch event.

3. The method of claim 2, wherein changing brightness of the user interface further comprises:

increasing brightness of the user interface to a predetermined brightness level, in response to detection of the touch event via the first touch sensor.

4. The method of claim 2, wherein changing brightness of the user interface comprises:

decreasing brightness of the user interface to a predetermined brightness level, in response to detection of the touch event via the second touch sensor.

5. The method of claim 2, wherein changing brightness of the user interface further comprises:

changing brightness of an area at which the touch event is detected.

6. The method of claim 2, wherein changing brightness of the user interface further comprises:

changing brightness of contents mapped to the area at which the touch event is detected.

7. The method of claim 1, further comprising:

determining a tilt angle according to a changing angle of the portable terminal; and

changing brightness of the user interface according to the brightness level corresponding to the determined tilt angle.

8. The method of claim 1, further comprising:

determining detection of a tilt angle according to the changing angle of the portable terminal; and

decreasing brightness of the user interface to a predetermined brightness level in response to detection of the checked tilt angle that is determined to a predetermined angle or more, and increasing brightness of the user interface to a predetermined brightness level in response to detection of the checked tilt angle that is determined less than the predetermined angle.

9. The method of claim 1, further comprising:

determining a cover signal detected from either side of the display unit covered; and

increasing brightness of the user interface to a predetermined brightness level in response to detection of the cover signal.

10. A portable terminal, comprising:

a touch screen comprising a display unit having two sides to display a user interface comprising a background screen and a content, and the touch screen to detect a touch event via a first touch sensor and a second touch sensor formed to each side of the display unit; and

a controller to control the display unit to change brightness of the user interface according to the touch event detected via the touch screen.

11. The terminal of claim 10, wherein the controller is configured to control increase brightness of the user interface to a predetermined brightness level and to display the user interface to the display unit in response to detection of the touch event via the first touch sensor, and to control the display unit to decrease brightness of the user interface to a predetermined brightness level and to display the user interface to the display unit in response to detection of the touch event via the second touch sensor.

12. The terminal of claim 11, wherein the controller is configured to control the display unit to change brightness of an area at which the touch event is detected.

13. The terminal of claim 11, wherein the controller is configured to change brightness of contents mapped to an area at which the touch event is detected.

14. The terminal of claim 10, further comprising:

a tilt angle detection unit to detect a tilt angle of the portable terminal.

15. The terminal of claim 14, wherein the controller is configured to control the display unit to decrease brightness of the user interface to a predetermined brightness level in response to detection of the tilt angle via the tilt angle detection unit that determined to a predetermined angle or more, and to control the display unit to increase brightness of the user interface to a predetermined brightness level in response to detection of the tilt angle that is determined to less than the predetermined angle.

16. The terminal of claim 10, further comprising:

a cover signal sensing unit to detect a cover signal transmitted from either side of the display unit that is covered.

17. The terminal of claim 16, wherein the controller is configured to control the display unit to increase brightness of the user interface to a predetermined brightness level in response to detection of the cover signal that is detected via the cover signal sensing unit.

18. A method, comprising:

receiving a touch event detected from a side of two-sided display device;

determining the touch event transmitted from each side of the display device based on a direction, a location, movement, duration of the detected touch event and tilt angle of the device, the determination corresponding to a user interface comprising a content and a background; and

adjusting brightness selectively to the content and the background according to the determined touch event.

19. The method of claim 18, further comprising:

determining an area, at which the touch event is detected, mapped with a predetermined brightness level, the mapping with the brightness level corresponding to the direction, location, tilt angle of the device and duration of the detected touch event.

20. The method of claim 18, wherein the content of the user interface comprises a content image, a letter, a figure and a number representing the user interface other than the background.
