What impact does the tempering process have on the performance of ultra-thin LCD panel substrate glass?

The tempering process has the following main effects on the performance of ultra-thin LCD panel substrate glass:
Enhanced strength: During the tempering process, the ultra-thin LCD panel substrate glass undergoes a delicate ion exchange process. This treatment takes advantage of a specific chemical principle, which is that when a smaller radius alkali metal ion (such as a potassium ion) is replaced by a larger radius alkali metal ion (such as a sodium ion), a tiny "squeeze" is generated on the glass surface. “pressure” effect. This effect results in the formation of a strong layer of compressive stress on the glass surface, significantly increasing the strength of the glass. After chemical tempering, the bending strength and impact strength of the ultra-thin LCD panel substrate glass have been greatly improved. Under normal testing conditions, its bending strength can reach 35 times that of ordinary glass, and its impact strength is as high as 510 times that of ordinary glass, which provides stronger protection for LCD panels.
Improved safety: Chemical tempering not only enhances the strength of the glass, but also significantly improves its resistance to rapid cooling and heating. This treatment allows the ultra-thin LCD panel substrate glass to easily cope with various temperature changes, and can usually withstand temperature differences of more than 150°C. This high degree of temperature stability makes the glass safer to use, reducing the risk of cracking or deformation due to temperature changes.
No softening deformation and optical performance: After specially designed stress distribution treatment, the ultra-thin LCD panel substrate glass shows excellent no softening deformation properties after tempering. Even under high temperature or high pressure environments, glass can maintain its original shape and size without deformation due to softening. At the same time, this treatment also ensures the excellent optical performance of the glass. Due to the existence of the surface compressive stress layer, the glass will not produce optical distortion, ensuring that the display effect of the LCD panel is clear and realistic.
Processability: Despite undergoing high-intensity tempering, the ultra-thin LCD panel substrate glass still maintains good processability. During the production process, the glass can be cut, polished and processed again as needed to meet the design and production needs of different products. This flexible processability provides more possibilities for the production of LCD panels.
Stress distribution and uniformity: During the tempering process, due to the different radii of the two alkali ions, the stress generated will change with the change of ion concentration. However, through precise process control and the stress relaxation phenomenon during heating, a certain balance between stress distribution and ion concentration distribution can be ensured. This balance allows the glass to maintain stress uniformity as a whole, thereby ensuring its stability and reliability in use.
Durability: Tempering treatment not only enhances the strength and safety of the ultra-thin LCD panel substrate glass, but also significantly improves its durability. This treatment enables the glass to maintain stable performance during long-term use and is less prone to problems such as aging, deformation or cracking. Therefore, the chemically tempered ultra-thin LCD panel substrate glass has a longer service life and higher reliability.
To sum up, the tempering process significantly improves the strength, safety, optical performance, processability and durability of the ultra-thin LCD panel substrate glass through specific processes, thereby ensuring the high-quality display effect and long-term performance of the LCD panel. stability.
