Problems solved by technology

[0011] However, the maximum brightness of the liquid crystal display module is determined by the brightness of the above-mentioned light-emitting lamp 6. Therefore, as shown in FIG. 3, the contrast rate (ContrastRate) of a high-definition image is lower than that of a low-definition image.
[0012] That is to say, according to the liquid crystal display module contrast adjustment method of the prior art, the brightness of the liquid crystal display module changes with the brightness of the light-emitting lamp 6, so the contrast rate of the image with higher definition is lower, therefore, the liquid crystal display module does not It is possible to obtain a sharp image with the change of resolution, which is the problem with this method

Abstract

The present invention relates to liquid crystal display module, and is especially the contrast regulating device and method of liquid crystal display module. The contrast regulating device consists of: liquid crystal display module, signal input part, signal processing part to process the input image signal into signal capable of being displayed, calibrator to convert the image signal into set resolution, storing part to store the image in frame unit, white pixel detecting part to detect at least one white pixel group and its white pixel percentage, and white brightness regulating part to regulate the white brightness of the white pixel group based on the percentage. The present invention makes it possible to obtain clear image.

Description

technical field [0001] The invention relates to a liquid crystal display module, in particular to a contrast adjustment device and an adjustment method of the liquid crystal display module. Background technique [0002] Generally speaking, as a flat-panel display device, a liquid crystal display is more recognized than a cathode ray tube display, and its average power consumption is much less than that of a cathode ray tube display with the same size screen, and the heat generation is also small, so , has attracted widespread attention in plasma displays (PDP: Plasma Display Panel), field emission displays FED (Field Emission Display), recent mobile phone screens, computer monitors, and television display devices. [0003] This kind of liquid crystal display is composed of two thin glass plates with special surface treatment, filled with solid and liquid intermediate liquid crystal substances, due to the voltage difference between the upper and lower glass plates, the arrang...
