Abstract

The invention provides a control board for a liquid crystal display. The liquid crystal display comprises a panel and an X board connected with the panel. The control board comprises a time sequence controller, a mura compensation function chip, a first memory, a second memory and an input output connector, wherein the time sequence controller is connected with the first memory, the X board, the mura compensation function chip and the input output connector; the mura compensation function chip is directly connected with the X board, the second memory and the input output connector; the X board stores a function code of the time sequence controller and mura compensation data of the liquid crystal display; and whether partial components of the control board need to be arranged is determined according to whether the panel of the liquid crystal display needs mura compensation. The invention also provides a liquid crystal display with the above control board. According to the control board and the liquid crystal display with the control board, waste of corresponding components when the panel needs no mura compensation can be avoided, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a control panel and a liquid crystal display with the control panel. Background technique [0002] Due to defects in the manufacturing process, the panels of existing liquid crystal displays generally have mura (uneven brightness). In order to improve the brightness uniformity of the panel, the existing mura compensation method uses a camera to capture grayscale images (pure white images with different brightness) ) of the mura shape, by comparing the brightness of the center of the panel, calculate the brightness difference between the surrounding area and the center position, and then reversely compensate the gray value of the mura position (the area brighter than the center position, reduce the gray value, become Darker; the darker area than the center, increase the grayscale value, brighten), so that the panel achieves a more consistent brightness. [0003] The existin...
