Restoration method of liquid crystal display panel and liquid crystal display panel

Abstract

The invention discloses a restoration method of a liquid crystal display panel. The method includes steps: S1, accurately aligning with a defect pixel on the liquid crystal display panel; S2, performing perforation on a position, corresponding to the defect pixel, of a color film substrate of the liquid crystal display panel to form an injection hole; S3, injecting black paint into the surface ofa color resistance material layer corresponding to the defect pixel through the injection hole; and S4, diffusing the black paint on the surface of the color resistance material layer to enable the whole defect pixel to be blackened. The whole defect pixel is blackened, light leakage due to penetration of a light of a back light source through the defect pixel is avoided, the defect pixel is in ablack state in any state, and the problem of the influence on the display effect of the whole liquid crystal display panel due to bright points of the defect pixel is solved. The invention also discloses a liquid crystal display panel, and the defect pixel in the liquid crystal display panel is restored through the above restoration method of the liquid crystal display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for repairing a liquid crystal display panel and the liquid crystal display panel. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. [0003] However, during the manufacturing process of the liquid crystal panel, when impurities such as dust, organic matter, and metal are adsorbed to the area near the color filter on the liquid crystal panel, the pixels corresponding to these color filters will emit brightness higher than other normal pixels. Much brighter light, this is called light leak, or bright pixel artifacts. The presence of such bright spot pixel defects will cause the liquid crystal display panel to...
