Abstract:
1. A display having a display power-saving mechanism, comprising: a display panel; a display control unit, coupled to the display panel for controlling displaying of the display panel; a backlight module for providing light required by the display panel for displaying; a backlight module control unit for controlling the light provided by the backlight module; and a power-saving control device for conducting comparison on frames data of two displayed frames of a plurality of successively displayed frames, and after a comparison result indicates that pixel difference between the two frames is less than a threshold value, judging whether the display is in a normal displaying status, wherein after a judgement result indicates that the display is in the normal displaying status, the power-saving control device determines whether the display needs to enter a power-saving operation mode by judging whether the successively displayed frames are still for a predetermined time, but if the judgement result does not indicate that the display is in the normal displaying status, the power-saving control device keeps the display in the power-saving operation mode without judging whether the successively displayed frames are still for a predetermined time, and after the judgement result indicates that the successively displayed frames are still for the predetermined time, the power-saving control device outputs a control signal of backlight power-saving to the backlight module control unit for adjusting the light emitted from the backlight module so as to control the backlight module to perform power-saving.
