Methods and Principles of Thinning

In the tablet display industry, the existing Panel Slimming processes are mainly divided into two categories: chemical etching (the mainstream method) utilizes chemical solutions to etch the surface of materials for Panel Slimming treatment. For example, it uses HF to react with the main component of silica (SiO2) in glass, causing it to dissolve, thereby Panel Slimming the thicker panel glass to the specified thickness. The surface smoothness of the panel glass after Panel Slimming must also meet the strict requirements of display devices.

Methods and Principles of Thinning

In the flat panel display industry, the existing Panel Slimming processes are mainly divided into two categories:

1. Chemical etching (mainstream method)

-- Using chemical solutions to etch the surface of materials for Panel Slimming treatment, such as the principle of using HF to react with the main component silicon dioxide SiO2 in glass and dissolve it, Panel Slimming the thicker panel glass to the specified thickness. The surface smoothness of the panel glass after Panel Slimming must also meet the strict requirements of display devices.

-- 6HF+SiO2->H2SiF6+2H2O

2. Physical grinding (auxiliary method)

-- Panel Slimming treatment of the glass surface of the LCD panel through mechanical grinding. Mainly used to improve the surface smoothness of the glass and for defect repair.
