Latest company news about How is the AG effect of capacitive touch screen achieved

The AG (Anti-Glare) effect of capacitive touch screens is achieved through a surface coating. The AG coating is a special coating material applied to the surface of capacitive touch screens to reduce light reflection and diffusion, thereby reducing screen glare.

AG coatings are typically composed of fine particles that scatter light, causing it to reflect in multiple directions rather than directly back to the observer of the touch screen. This scattering effect helps to reduce reflections and refractions of light, thereby decreasing surface glare on the screen.

The implementation process of AG coating typically involves the following steps:

1. Cleaning the screen surface: Before applying the coating, the surface of the touch screen needs to be thoroughly cleaned to ensure proper adhesion of the coating.

2. Applying the AG coating: Using specialized coating techniques, the coating material containing AG particles is evenly applied to the surface of the touch screen. The coating is usually transparent and does not significantly affect the display quality of the screen.

3. Drying and curing: After the coating is applied, the touch screen undergoes an appropriate drying and curing process to ensure that the AG coating adheres firmly to the screen and forms a smooth surface.


The main purpose of AG coating is to reduce screen glare and reflections on the touch screen, providing a better visual experience. It can improve screen visibility in bright environments and reduce visual fatigue caused by reflections and glare. AG coatings are widely used in many touch screen applications, especially in outdoor and high-light environments.
