1.The principle of capacitive touch screen is based on the coupling capacitance formed between the human body (or conductive object) and the screen surface, the finger touch changes the capacitance value, and the controller determines the touch point position.It is divided into :

• Surface capacitive type,glass surface coated with conductive layer,finger touch and conductive layer to form capacitance,change at different position to determine the touch position.  
• Projected capacitive type：With matrix structure, the electrode array is made in glass or thin film, and the capacitance between the electrodes near the touch point is changed by finger touch, and the touch position is accurately determined by measuring the change.

2.Feature.

• Multi touch:

capacitive touch screen monitor support multi touch operation,which can recognize multiple touch position at the same time and realize gesture operation such as zoom, rotate and so on.

• Sensitive operation：

Capacitive touch display has fast response to touch and high touch accuracy,which can accurately capture subtle finger movements.

• Exquisite and nice look：

The surface of capacitive touch screen panel is flat and smooth,which is usually made of glass.And it has higher light transmittance and clearly display effect.Good durability.

Compared with resistive touch screen,capacitive touch screen are more resistant to wear and longer service life.

3.Application scenarios.

It is widely used in various electronic devices  such as smart phone, tablets, laptops, smart watches and some industrial control,medical equipment, self-service terminals and other fields. With the development of technology,the performance and function of capacitive touch screen keep improving and bring users a more convenient and efficient interactive experience.
