Patent ID: 8233014

Claim:
A power saving method for a color sequential display, comprising: determining whether a frame received by an image processing terminal of the color sequential display is static or dynamic; determining whether the color sequential display activates a backlight mode; and reducing a first frame rate used by a graphics engine of the image processing terminal, and reducing a second frame rate of the color sequential display in outputting frames, according to a result of whether the frame is static or dynamic and whether the backlight mode is activated, wherein reducing the first frame rate and the second frame rate according to the result of whether the frame is static or dynamic and whether the backlight mode is activated comprises: reducing the first frame rate to a first image processing critical frame rate, while the frame rate is dynamic and when the backlight mode is activated; reducing the first frame rate to a second image processing critical frame rate or below, while the frame is dynamic and when the backlight mode is not activated; and reducing the first frame rate to a third image processing critical frame rate, while the frame is static; wherein the first image processing critical frame rate is higher than the second image processing critical frame rate, and the second image processing critical frame rate is higher than the third image processing critical frame rate; wherein both the first and second image processing critical frame rates are not less than zero.
