2. Structure of capacitive touch screen

Capacitive touch screens usually use glass as the base of the touch panel, which is coated with a transparent conductive layer and covered with an anti-scratch coating. The transparent conductive layer is generally evenly distributed on the entire touch panel and can be made through a fine micro-line grid or uniform coating. The conductive layer will also be covered with a coating insulating layer to protect the transparent conductive layer.

3. Characteristics of capacitive touch screen

High sensitivity: The capacitive touch screen is based on the principle of capacitance change and is more sensitive to touch. No need to press hard when touching, just touch it lightly to operate.

Fast response speed: The response speed of the capacitive touch screen is very fast, and the feedback of touch operations is almost real-time.

Support multi-touch: The capacitive touch screen can detect multiple touch points at the same time and realize multi-touch function. This allows users to use their fingers to perform various gesture operations such as zooming, rotating, and sliding.

High light transmittance: The light transmittance of the capacitive touch screen is very good and will hardly affect the display effect.

Wear resistance: The capacitive touch screen uses a wear-resistant coating, which has good wear resistance and long service life.
