1. Display hot pressing: The hot pressing process is covered with a layer of flexible film or conductive rubber. The film constitutes a flexible connection between the circuit board composed of two thin glass plates and the display panel. In 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, improve adhesion, thereby improving bonding quality and reducing scrap rate. This also applies to the process flow of hot pressure welding and precision welding. 2. Display assembly: In the assembly process, such as the evaporation of the glass substrate or the sputtering of the ITO film, the cleaning is difficult due to the dirty surface of the glass, and the cleaning effect cannot be achieved. Plasma cleaning can effectively remove surface grease and dust. Plasma treatment before ITO glass is coated with photoresist can effectively improve surface wettability, remove contaminants, reduce bubble products, and remove residual chemicals after pattern transfer. In the liquid crystal module bonding process, organic pollutants such as spilled glue, polarizers, and anti-fingerprint films will be removed during the bonding process. Clean and activate the surface. 3. Display glass: spray a layer of special paint on the surface of the display. The coating can improve the scratch resistance of the display and improve the surface quality of PC (polycarbonate) and PMMA (polymethyl methacrylate) displays. In order to ensure that the coating has good adhesion, the surface must be pretreated. Using Guoxing low-temperature plasma technology for surface treatment can simplify the process flow of display production and greatly reduce the rejection rate.
