DISPLAY POWER SAVING METHOD AND ELECTRONIC SYSTEM
First Claim
1. A display power saving method for an electronic system that includes a display device including a light emitting diode panel, the display power saving method comprising:
- detecting whether a pointing device exists in the electronic system;
obtaining the location of a pointer controlled by the pointing device when detecting the pointing device existing in the electronic system;
determining a display area of a screen of the display device according to the location of the pointer;
recognizing whether a power management mode of the electronic system is a power saving mode; and
decreasing the brightness of an area of the screen other than the display area when recognizing that the power management mode is the power saving mode.

13. An electronic system with a display power saving function comprising:
-
a display device including a light emitting diode panel; a memory unit for storing data displayed on a screen of the display device; a processing unit coupled to the display device and the memory unit, utilized for; detecting whether a pointing device exists in the electronic system; obtaining the location of a pointer controlled by the pointing device shown on the screen of the display device when the pointing device is detected; determining a display area of the screen of the display device according to the location of the pointer; recognizing whether a power management mode of the electronic system is a power saving mode; and generating a plurality of control signals for controlling the brightness of the light emitting diode panel to decrease the brightness of an area of the screen other than the display area when recognizing that the power management mode is the power saving mode; and a display driving unit coupled to the light emitting diode panel and the processing unit, for generating a plurality of driving signals to drive the light emitting diode panel. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
