Grinding treatment method for thinned liquid crystal glass substrate

Abstract

The invention belongs to the technical field of grinding for the thinning process of liquid crystal glass substrates, and discloses a grinding treatment method for a thinned liquid crystal glass substrate. By the adoption of the grinding treatment method for the thinned liquid crystal glass substrate, the defects of existing grinding techniques for thinning are overcome. The grinding treatment method for the thinned liquid crystal glass substrate comprises the following steps of preparation of grinding fluid, cleaning of a grinding machine, and grinding through the grinding machine. The grinding treatment method for the thinned liquid crystal glass substrate has the beneficial effects that mechanical scratches on the surface of the liquid crystal glass substrate can be obviously reduced effectively and conveniently, the surface grain yield of the ground liquid crystal glass substrate is increased, the probability of regrinding after grinding is lowered, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal glass substrate thinning process grinding, and in particular relates to a method for grinding a liquid crystal glass substrate after thinning. Background technique [0002] Flat panel displays include liquid crystal displays (LCDs), touch panels (TPs), plasma displays (PDPs), and organic electroluminescent devices (OLEDs). Liquid crystal display devices are attracting the most attention among flat panel display devices because they provide clear images with excellent resolution, consume less power, and can make display screens thinner. Liquid crystal display devices are used in mobile devices including mobile phones, notebook PCs, and televisions. [0003] At present, the thinning of liquid crystal glass substrates mainly adopts chemical thinning technology, and the process includes: sealing glue curing, chemical thinning, cleaning after thinning, grinding, manual cleaning after grinding, ...

AI Technical Summary

Problems solved by technology

With the development of technology, the thinning of ultra-large and ultra-thin LCD panels has become the mainstream in the industry. The grinding fluid is the main material for grinding and polishing of the liquid crystal glass substrate thinning process, and the grinding fluid has become a difficult point for the surface yield of the liquid crystal substrate after grinding. The traditional grinding liquid is made of tap water and grinding powder with a particle size of 1.7 μm. The filter setting is generally filtered by anti-static gloves or stockings. After grinding, the surface of the liquid crystal substrate will mostly have mechanical scratches and incoming bumps that have not been cleaned. The yield rate of liquid crystal substrates cannot meet customer needs and high throwback affects production efficiency
