Embodiment Construction

[0057] 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 and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0058] see figure 1 , a repair method for bad display of a monitor, comprising the following steps:

[0059] Step 102: Obtain the grayscale value of each pixel corresponding to the input image, and confirm whether the position of each pixel is within the bad display area according to the lookup table.

[0060] Specifically, the lookup table is a relational table of the luminance value of the normal area except the bad display area in the input image, the luminance value of each pixel in the bad display area, and the corresponding grayscale value, and the lookup table records the relationship table...

Abstract

The invention relates to a restoration method and device against display failure of a display device. The restoration method comprises that the gray scale value of each pixel point corresponding to an input image is obtained, and whether the position of each pixel point is within a display failure area is confirmed according to a look-up table; if the positions of the pixel points are within a display failure area, whether restoration values corresponding to the gray scale values of the pixel points within the display failure area can be found in the look-up table is determined; if YES, the pixel point is resorted via the look-up table, the corrected gray scale values of the pixel points are obtained; and an image corresponding to the corrected gray scale values is displayed. According to the invention, the correction values corresponding to the pixel points which need correcting can be found rapidly via the look-up table, and the pixel points in the display failure area can be restored rapidly and effectively.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a method and device for repairing defective display of a display. Background technique [0002] Due to reasons such as thin-film technology and uneven distribution of backlight brightness, displays have certain Mura (bad display) defects. Mura defect refers to the phenomenon that the display brightness of the display is uneven, resulting in various traces. Mura defects will affect the module yield and display effect. Contents of the invention [0003] Based on this, it is necessary to provide a method and a device for repairing defective display of a display for the problems of how to repair the defective display in the display and the poor yield rate of the module. [0004] A method for repairing bad display of a monitor, comprising the following steps: [0005] Obtain the grayscale value of each pixel corresponding to the input image, and confirm whether the position of e...
