[0002] LCD glass is the abbreviation of liquid crystal display, which is a display technology widely used in various electronic products. The LCD glass manufacturing process can be simply divided into six steps: substrate preparation, conductive and gate preparation, liquid crystal material filling, packaging, module preparation and assembly testing.

[0003] In the substrate preparation process, the glass substrate needs to be cleaned with solutions such as acid, alkali and deionized water to remove dirt and impurities on the surface, so that the optical film can be coated on the glass surface to improve the optical transparency and reflectivity.
