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

Embodiment Construction

[0038] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0039] see Figure 5 and Figure 6 , the present invention firstly provides a liquid crystal display panel Mura compensation optimization method, comprising the following steps:

[0040]Step S1, the timing controller 11 receives the original picture data signal input by the liquid crystal display panel 1 and detects the received original picture data signal to determine whether the original picture is a gray-scale transition picture or a single gray-scale value picture;

[0041] Step S2, when it is determined that the original picture is a gray-scale transition picture or not a single gray-scale value picture, the timing controller 11 turns off the mura compensation function;

[0042] Step S3 , when it is determined that the original picture...

Abstract

The present invention provides a liquid crystal display panel Mura compensation optimization method and system. The method comprises the steps of: performing detection of received original frame datasignals and determining whether the input original frame is a gray-scale transition frame or a single gray-scale value frame, and when it is determined that the original frame is the gray-scale transition frame or is not the single gray-scale value frame, closing an Mura compensation function. The liquid crystal display panel Mura compensation optimization method and system can avoid the phenomenon of abnormal display caused by Mura compensation in a special frame which is the gray-scale transition frame or is not the single gray-scale value frame so as to optimize the Mura compensation effectof the liquid crystal display 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...
