Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 It is a schematic structural diagram of a defective display repair system for a liquid crystal display panel according to an embodiment of the present invention, and reference is made below figure 1 To detail the components and functions of the system.

[0029] Such as figure 1 As shown, the system includes a camera 10 , a control board 20 and a liquid crystal display panel (display panel for short) 30 electrically connected to the control board 20 .

[0030]Before detection, a driver (not shown) needs to be used to light up the display panel 30, and the display panel can be driven to a specific gray scale, for example, it can be in a state of full brightness, 50% gray scale or full darkness. In this example, from figure 1 It can be seen from t...

Abstract

The invention discloses a system and method for repairing a bad display area of a liquid crystal display panel. The system for repairing the bad display area of the liquid crystal display panel comprises an image acquisition device, a distortion-free compression module, a storage and a color spot repair module, wherein the image acquisition device is used for acquiring data of images, containing the bad display area, of the liquid crystal display panel, the distortion-free compression module is used for carrying out difference operation on the collected data of the images to achieve distortion-free compression processing, the storage is used for storing the compressed data processed through distortion-free compression processing, and the color spot repair module is used for carrying out decompression processing on the compressed data stored in the storage, carrying out color spot repair on the decompressed original data of the images to generate feedback information, and sending the feedback information back to the liquid crystal display panel. According to the system and method for repairing the bad display area of the liquid crystal display panel, due to the facts that values of the images which will be stored in the storage, and contain data of the bad display area are processed through distortion-free compression and decompression, then, color spot repair is carried out, and the information is output to the liquid crystal display panel, the storage size of the storage can be reduced, the manufacturing cost is reduced, and the De-Mura processing effect cannot be reduced.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a defective display repairing system and repairing method of a liquid crystal display panel. Background technique [0002] In recent years, with the thinner display trend, Liquid Crystal Display (LCD for short) has been widely used in various electronic products, such as mobile phones, notebook computers, and color TV sets. [0003] In engineering, pressure, scratches, offsets, vibrations, pollution caused by equipment and tools, or changes in pixel characteristics caused by the influence of ambient temperature and driving conditions, may eventually be seen in the display monitor. display unevenness. Various traces caused by uneven brightness on the display screen are collectively referred to as display unevenness (Mura). There are three main manifestations of display unevenness: (1) a little dark display part can be seen in a white picture; (2) a little white display part can be see...
