Introduction of domestically etched AG aluminum-silicon glass
Different from soda-lime glass, aluminosilicate glass has superior flexibility, scratch resistance, bending strength and impact strength, and is widely used in PID, automotive central control panels, industrial computers, POS, game consoles and 3C products and other fields. The standard thickness is 0.3~2mm, and now there are also 4mm, 5mm aluminosilicate glass to choose from.
The anti-glare glass of the touch panel processed by chemical etching process can effectively reduce the glare of high-resolution displays, making the picture quality clearer and the visual effect more realistic.
