Abstract
This disclosure provides a method and apparatus for controlling liquid crystal display brightness, and a liquid crystal display device, and relates to the field of liquid crystal display technologies, where the method includes: determining grayscale values of all pixels in a zone image data block under a predetermined rule according to a received image signal, and pre-obtaining a zone backlight value corresponding to the zone image data block according to the grayscale values; multiplying the pre-obtained zone backlight value with a backlight value gain coefficient to obtain a backlight value of a backlight zone corresponding to the zone image data block to which a gain is applied, wherein the backlight value gain coefficient is more than 1; and outputting the backlight value of the backlight zone to a driver circuit of backlight source in the backlight zone to control the brightness of the backlight source in the backlight zone as a result of driving, thus improving the effect of contrast quality of pictures displayed by the liquid crystal display device.
