Abstract

The invention discloses a method for extracting foreign materials from a liquid crystal panel, relates to the technical field of display and is invented for solving the problems of difficulty in sampling and inaccuracy of sampling of foreign materials in the liquid crystal panel. The method for extracting the foreign materials from the liquid crystal panel comprises the following steps of determining and marking positions where the foreign materials are located in the liquid crystal panel; cooling the liquid crystal panel to enable viscosity of liquid crystal molecules to be increased; extracting the foreign materials. The method is used for extracting the foreign materials from the liquid crystal panel and analyzing the foreign materials and is used for reducing poorness of the liquid crystal panel, which is caused by the foreign materials.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for extracting foreign matter in a liquid crystal panel. Background technique [0002] Generally, a liquid crystal panel includes two opposite substrates and a liquid crystal layer located between the two substrates, and the sealing of the liquid crystal panel is completed with a sealant. There are various defects in the liquid crystal panel, among which foreign matter in the liquid crystal panel is an important factor leading to the defect of the liquid crystal panel. [0003] In order to reduce foreign matter entering the liquid crystal panel and reduce the probability of defective liquid crystal panels, it is necessary to take out the foreign matter existing in the liquid crystal panel and conduct corresponding analysis, so as to obtain the source of the foreign matter and take measures to reduce the foreign matter entering the liquid crystal panel. [0004] However...
