Abstract

A mobile electronic device is disclosed. A first display module comprises a first touch panel, and a second display module comprises a second touch panel. A battery supplies power to the first display module and the second display module, and a detection module determines whether the first touch panel and the second touch panel are viewable by a user. A setting module sets the first touch panel to a first brightness, if the battery level is below the first value and if the second touch panel is not viewable (non-viewable) by the user. The setting module sets the first touch panel and the second touch panel to a second brightness darker than the first brightness, if the battery level is below the first value and if the second touch panel is viewable by the user.

Claims

1. A mobile electronic device, comprising:

a first display module comprising a first touch panel;

a second display module comprising a second touch panel;

a battery operable to supply power to the first display module and the second display module;

a detection module operable to determine whether the first touch panel and the second touch panel are viewable by a user; and

a setting module operable to set the first touch panel to a first brightness if a battery voltage of the battery is below the first value and if the second touch panel is not viewable by the user, and to set the first touch panel and the second touch panel to a second brightness darker than the first brightness if the battery voltage is below the first value and if the second touch panel is viewable by the user.

2. The mobile electronic device according to claim 1, further comprising a first housing and a second housing, wherein the first housing comprises the first display module and the second housing comprises the second display module.

3. The mobile electronic device according to claim 2, wherein the second display module is covered by the first housing.

4. The mobile electronic device according to claim 1, wherein the setting module is further operable to set the first display module to the first brightness, if the second display module becomes non-viewable by the user when both the first display module and the second display module are set to the second brightness.

5. The mobile electronic device according to claim 4, wherein the setting module is further operable to turn off at least one of the first display module and the second display module if the battery voltage is below a second value lower than the first value.

6. The mobile electronic device according to claim 4, further comprising an application-execution determination module operable to determine whether an application is being executed, wherein the setting module is further operable to keep turning on both the first touch panel and the second touch panel if an application is being executed and if the voltage is below a second level.

7. The mobile electronic device according to claim 4, wherein the setting module is further operable to set a screen of the first display module and the second display module that is not off to a third brightness darker than the second brightness, if one of the first display module and the second display module is turned off.

8. The mobile electronic device according to claim 4, wherein the setting module is further operable to set the first display module to the first brightness if the second display module becomes non-viewable by the user while one of the first display module and the second display module is turned off.

9. The mobile electronic device according to claim 4, wherein

the first touch panel comprises a first input module operable to detect user touch operations;

the second touch panel comprises a second input module operable to detect the user touch operations; and

the setting module is further operable to set a turned-off touch panel of the first touch panel and the second touch panel to a third brightness darker than the second brightness, if a user touch operation is detected on the turned-off touch panel.

10. A method for operating a mobile electronic device, comprising:

setting a first touch panel to a first brightness, if a battery voltage falls below a first value and a second touch panel is not viewable by a user; and

setting the first touch panel and the second touch panel to a second brightness darker than the first brightness, if the battery voltage falls below the first value and the second touch panel is viewable by the user.

11. The method according to claim 10, wherein a first housing comprises the first touch panel and the second housing comprises the second touch panel.

12. The method according to claim 11, wherein the second touch panel is covered by the first housing.

13. The method according to claim 10, further comprising setting the first touch panel to the first brightness, if the second touch panel becomes non-viewable by the user when both the first touch panel and the second touch panel are set to the second brightness.

14. The method according to claim 13, further comprising turning off at least one of the first touch panel and the second touch panel, if the battery voltage falls below a second value lower than the first value.

15. The method according to claim 13, further comprising keeping the first touch panel and the second touch panel on, if an application is being executed and the battery voltage is below a second level.

16. The method according to claim 13, further comprising setting a touch panel to a third brightness darker than the second brightness, if one of the first touch panel and the second touch panel is turned off.

17. The method according to claim 13, further comprising setting the first touch panel to the first brightness, if the second touch panel becomes non-viewable by the user while one of the first touch panel and the second touch panel is turned off.

18. The method according to claim 13, further comprising setting a turned-off touch panel of the first touch panel and the second touch panel to a third brightness darker than the second brightness, if a user touch operation is detected on the turned-off touch panel.
