Abstract

A mobile terminal is disclosed. In one embodiment, the mobile terminal includes a display implemented by using an organic light emitting display device, a memory storing a graphic user interface (GUI) of low brightness, a key input unit to enable the input of whether the graphic user interface of low brightness can be used, a light quantity detector detecting light quantity from the external and a controller converting and establishing into the graphic user interface stored in the memory depending on a use selection of the graphic user interface or the light quantity value detected in the light quantity detector.

Claims

1. A mobile terminal, comprising:

a self-emissive display unit configured to display an image;

a memory configured to store first and second image portions, wherein the first image portion is adapted to display an image at a first brightness and the second image portion is adapted to display an image at a second brightness different from the first brightness; and

a controller configured to select one of the first and second image portions.

2. The mobile terminal as claimed in claim 1, wherein the first brightness is greater than the second brightness.

3. The mobile terminal as claimed in claim 2, wherein the controller is further configured to select one of the two image portions based on user input.

4. The mobile terminal as claimed in claim 3, further comprising an input unit configured to receive user input so as to select the second image portion.

5. The mobile terminal as claimed in claim 2, further comprising a sensor configured to detect an ambient brightness level.

6. The mobile terminal as claimed in claim 5, wherein, when the detected level is less than a reference level, the controller is further configured to select the second image portion.

7. The mobile terminal as claimed in claim 2, wherein the second brightness is less than about 1 cd/m².

8. The mobile terminal as claimed in claim 7, wherein the first brightness is in the range of about 10 to about 300 cd/m².

9. The mobile terminal as claimed in claim 1, wherein the self-emissive display unit is an organic light emitting display unit.

10. A method of controlling a mobile terminal, comprising:

displaying, at a self-emissive display unit, an image which includes a background portion and a non-background portion; and

controlling the self-emissive display unit such that the brightness of the non-background portion is higher than that of the background portion.

11. The method of claim 10, further comprising receiving user input, wherein the controlling is performed based on the user input.

12. The method of claim 10, further comprising detecting an ambient brightness level, wherein the controlling is performed based on the detecting.

13. A mobile terminal, comprising:

a self-emissive display unit configured to display an image which includes a background portion and a non-background portion; and

a controller configured to control the self-emissive display unit such that the brightness of the non-background portion is higher than that of the background portion.

14. The mobile terminal as claimed in claim 13, wherein the brightness of the background portion is less than or equal to about 1 cd/m².

15. The mobile terminal as claimed in claim 14, wherein the brightness of the non-background section is in the range of about 10 to about 300 cd/m².

16. The mobile terminal as claimed in claim 13, wherein the non-background portion includes at least one of the following:

a stilled image, a video image and text.

17. The mobile terminal as claimed in claim 13, further comprising an input unit configured to receive user input, wherein the controller is further configured to control the self-emissive display unit based on the received user input.

18. The mobile terminal as claimed in claim 13, wherein the self-emissive display unit is an organic light emitting display unit.

19. A mobile terminal, comprising:

a self-emissive display unit configured to display an image;

a memory configured to store first and second image portions, wherein the first image portion is adapted to display an image at a first brightness and the second image portions is adapted to display an image at a second brightness different from the first brightness;

an input unit configured to receive user input so as to select the second image portion;

a sensor configured to detect an ambient brightness level; and

a controller configured to select one of the first and second image portions based on at least one of the user input and the detected level.

20. The mobile terminal as claimed in claim 19, wherein the second brightness is less than about 1 cd/m² and the first brightness is in the range of about 10 to about 300 cd/m².
