The method of preventing pollution in the cog binding process of LCD screen

Abstract

The invention discloses a depollution method in the binding process of a liquid crystal display COG. The depollution method comprises the steps that a full wafer glass with multiple lines of single particle glass cases is cut on a cutting machine, the full wafer glass is thrashed into multiple strips of liquid crystal cell integration with two lines of single particle glass cases as unit, and the single particle liquid crystal cell in each line is coincided with the electrode of the corresponding single particle liquid crystal cell in the other line; liquid crystal perfusion, sealing and polaroid pasting are conducted, the liquid crystal cell integration is thrashed into single particle liquid crystal cells, and COG binding is conducted in the electrode of each single particle liquid crystal cell. The depollution method in the binding process of the liquid crystal display COG has the advantages that a method that conducting adequate protection on the electrode is adopted, the electrode exposing outward too early is avoided, and pollution to the electrode in the following processes is prevented; compared with the prior art, the clean-out operation process before the COG binding is cancelled, both materials and labor cost are saved, the energy consumption is lowered, and the quality of the liquid crystal display is guaranteed.

Description

technical field [0001] The invention relates to liquid crystal manufacturing technology, in particular to a method for preventing electrode pollution in COG binding of liquid crystal screens. Background technique [0002] In the prior art, the process of LCD screen filling from crystal filling to COG binding is as follows: glass cutting and granulation—liquid crystal filling—cleaning—LCD screen (single crystal) detection—cleaning—polarizer—appearance inspection ——(Packaging)——Transportation—Cleaning before bonding——COG bonding. Before filling, the glass is made into a single grain or a single row. At this time, the electrodes are completely exposed, which is easy to cause pollution, and in the subsequent In the process of detection, cleaning and transportation, it is also easy to cause secondary pollution, which affects the quality of the LCD screen.
