Embodiment Construction

[0031] The present invention provides a method and system for adjusting the screen consistency of a liquid crystal display. In order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] see figure 1 , figure 1 It is a flowchart of a preferred embodiment of the method for adjusting the screen consistency of a liquid crystal display provided by the present invention. As shown in the figure, the method includes the following steps:

[0033] Step S100, dividing the liquid crystal display screen into multiple regions, and calculating the GAMMA curve corresponding to each region;

[0034] Step S200, correcting the pixel signals of each area by using the G...

Abstract

The invention discloses a liquid crystal display screen picture consistency adjusting method and system. The liquid crystal display screen is divided into a plurality of areas and then a Gamma curve corresponding to each area is calculated; a pixel signal of each area is corrected by the corresponding Gamma curve of each area and RGB data of each area after the correction can be achieved; Gamma voltage is correspondingly adjusted according to the RGB data of each area, so each area of the liquid crystal display screen can be input on the same picture and output the same gray scale signal; and picture color consistency can be improved. A present TV framework structure is employed, so hardware cost cannot be increased and great convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method and system for adjusting the picture consistency of a liquid crystal display. Background technique [0002] The rich colors of the LCD screen are due to the color filters of the LCD screen. The three primary colors of R, G, and B (or the four colors of RGBW) of the color filter are arranged in a certain pattern, and correspond to the TFT sub-pixels of the TFT substrate one by one. The white light emitted by the backlight becomes the corresponding R, G, B color light after passing through the filter film. The voltage value applied to each sub-pixel is adjusted through the TFT array, thereby changing the transmission intensity of each color light. RGB color lights of different intensities are mixed together to achieve color display. Under the condition of designing the same production process and the same parameters, the ideal LCD screen should provide th...
