Aqueous cleaning agent for liquid crystal display

Abstract

The invention discloses a LCD water-based abluent of amine alkali and non-ion surface activator, which comprises the following parts: 20-70 percent amine alkali, 5-40 percent JFC, 5-20 percent non-ion surface activator and deionized water. The invention is beneficial to remove the surface residues, which improves the surface finishment of product.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent suitable for cleaning liquid crystal display screens. Background technique [0002] Liquid crystal is a kind of substance with special properties. It maintains the unique characteristics of crystals that can be arranged in three-dimensional space within a certain range in a liquid state. The liquid crystal material used on the liquid crystal display is an organic compound with structures such as cholesteryl ester, cyanobiphenyl, and phenylcyclohexane. After the liquid crystal material is encapsulated between two pieces of conductive glass, there will always be excess liquid crystal material remaining around it. If it is not removed, it will affect the performance of the liquid crystal display. In severe cases, the electrode leads will even be corroded, causing the whole machine to be scrapped. With the rapid development of microelectronic technology, higher requir...

Problems solved by technology

However, the water-based cleaning agents that can be used at home and abroad are still not perfect.

Water-based cleaning to remove residual liquid crystals from LCD is mainly based on the emulsification of surfactants and liquid crystals. The emulsification is more dependent on ultrasound, and the surface tension of water is greater than that of solvents. The wettability of the slit is poor and affects the slit. Cleaning of residual LCD in

At present, the best application is Kao in Japan, but its promotion and use are limited due to its high price.
