Abstract

The invention provides a method for repairing a pixel bright spot. The method comprises the following steps of: cutting off a transparent electrode at the pixel bright spot; and cutting connection between a transparent electrode on a pixel electrode side and a transparent electrode on a color filter side. The method for repairing the pixel bright spot is simple; and the efficiency for repairing the pixel bright spot can be effectively improved.

Description

technical field [0001] The invention relates to a liquid crystal panel (TFT-LCD) repair technology, in particular to a method for repairing pixel bright spots applied in the liquid crystal panel. Background technique [0002] During the manufacture of the liquid crystal panel, foreign matter including dust, organic matter, metal, etc. will be absorbed into the liquid crystal panel. When foreign objects are attracted to areas close to certain color filters, the pixels corresponding to these color filters will emit light much brighter than the brightness of the rest of the normal pixels, which is called pixel bright spots. [0003] Existing technologies for repairing pixel bright spots caused by foreign matter mainly include: BM covering method and CF carbonization method, among which [0004] The BM (black matrix) covering method mainly uses laser to form a gap at the color filter with pixel bright spots or between the color filter and the glass substrate, and uses laser dec...
