Liquid crystal display panel mura compensation optimization method and optimization system

Abstract

The invention provides a liquid crystal display panel Mura compensation optimization method and an optimization system. The liquid crystal display panel Mura compensation optimization method detects the received original picture data signal and determines whether the input original picture is a gray scale transition picture or a single gray scale value picture, when it is determined that the original picture is a gray scale transition picture or not a single When the grayscale value screen is used, the Mura compensation function is turned off; it can avoid the phenomenon of abnormal display caused by Mura compensation in certain screens such as grayscale transition screens or non-single grayscale value screens, and optimize the Mura compensation effect of the LCD panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel Mura compensation optimization method and optimization system. Background technique [0002] Liquid Crystal Display (LCD) panels have developed rapidly in recent years and have become mainstream products in the market and are widely used: such as TVs, smart phones, tablet computers, and computer screens. [0003] Under the existing technical conditions, due to poor raw materials or some uncontrollable factors in the actual manufacturing process, LCD panel products often have uneven brightness when displaying images, which is called the Mura phenomenon in the industry, especially in LCD panels. The Mura phenomenon is particularly noticeable when the display panel displays a white picture. [0004] In order to eliminate the mura on the liquid crystal display panel and improve product quality, the display panel manufacturer will use the mura compensa...

Problems solved by technology

[0005] The above-mentioned existing mura compensation system has certain technical defects: as long as there is a gray scale compensation value, the timing controller 500 will perform mura compensation in all screens, but performing mura compensation in some specific screens will cause abnormal display : for example in image 3 In the horizontal or vertical gray-scale transition picture shown, the input gray-scale values ​​of the regions of the liquid crystal display panel 200 are different (the difference between adjacent regions is one gray-scale). The level value may become the same, or the difference is less than one gray level, which will cause the transition boundary of the gray level to be unclear, forming such as Figure 4 The grayscale transition shown is not smooth and abnormal, which affects the quality judgment of LCD panel products
