Information
1. LCD display assembly
In LCD display assembly, many processes require plasma treatment technology. For example, before evaporating or sputtering ITO film on glass substrate, it is difficult to clean the glass surface due to the dirty glass surface, and the cleaning effect cannot be achieved. Effectively remove surface grease, dust and other pollutants, so as to achieve the purpose of clean cleaning; plasma treatment before ITO glass coating photoresist can effectively improve surface wettability, remove pollutants, reduce air bubbles, and remove residuals after pattern transfer Chemicals. In the LCD module bonding process, organic pollutants such as spilled glue, polarizers, anti-fingerprint films, etc. are removed during the surface cleaning and activation.
2. LCD display hot pressing
The displays of digital instruments, radios, on-board computers, mobile phones and notebook computers are often covered with a layer of flexible film or conductive rubber through the use of hot pressing technology. This film constitutes a flexible connection between the circuit board and the display panel formed by two thin glass plates. During the production process, fingerprints, oxides, organic pollutants, and various cross-pollutants will significantly affect the quality of related processes in the production process and reduce the adhesion between the film and the display panel. The plasma pretreatment process can completely remove organic pollutants and other impurities on the surface of the glass and improve the adhesion, thereby improving the bonding quality and reducing the rejection rate. This also applies to the process flow of hot pressure welding and precision welding.
