Abstract
The present disclosure provides a method for lowering power consumption of liquid crystal display, wherein includes: calculating an average brightness of all pixels when displaying the image; comparing the average brightness with a preset brightness; determining whether at least one string in the multi-string LED light string in parallel is turned off according to the comparison result. The present disclosure further discloses a liquid crystal display using the method for reducing the power consumption of the liquid crystal display. The present disclosure can reduce the power consumption of the backlight module to achieve the power saving effect without affecting the screen display effect.
Claims16
A method for lowering power consumption of liquid crystal display, wherein, comprises:
- calculating an average brightness of all pixels when displaying the image;
- comparing the average brightness with a preset brightness;
- determining whether at least one string in the multi-string LED light string in parallel is turned off according to the comparison result.
A liquid crystal display, comprises a liquid crystal panel and a backlight module arranged in opposing relation, the liquid crystal panel comprises a plurality of pixels and a control chip, the backlight module comprises the multi-string LED light string in parallel and a controller used to control the LED light string, the control chip is used to receive a image data from an external system, the plurality of pixels is used to display image based on the image data and provided by the multi-string LED light string in parallel, wherein, when the plurality of pixels displaying image, the control chip is further used to calculate the average brightness when the plurality of pixels displaying image, and further comparing the average brightness with the preset brightness;
- the controller is further used to determine whether at least one string in the multi-string LED light string in parallel is turned off according to the comparison result.
