Projected Capacitive Large Touch Screen 32 Inch For Advertising Machine

Operation Principle:

Capacitive Touch Panel is to use the working current of induction of human body.The operational principle of the projected capacitive touch panel: There are two layers of the ITO layer under the surface of glass. This ITO layer respectively forms the electric field of X axis and Y axis, which can keep balance by crossing the surface of the class. Once the fingers approach the glass surface, the fingers and the electrode X axis or Y axis will form a new electric field, which can make the local capacitance change. Then the controller will determine the location based on capacitance changes.

Projected Capacitive touch screen Features:

1) Response speed fast, smooth touch.

2) Flat panel, more high-end atmosphere, eliminating infrared touch screen surface with a groove edges are not allowed to shortcomings.

3) Precision-touch capacitive screen is using the body's current-sensing.

4) Accuracy up to 99% proficient in writing, no break no drift.

5) Any point can withstand more than 50 million times touch.

6) Explosion-proof and durable, scratch-resistant, anti-collision, anti-radiation within the core capacitive touch ensure stable, anti-interference ability.

7) Operating systems strong compatibility.

8) Intelligent automatic calibration, use forinternal / external variety of environments.

9) Long life, low maintenance costs.
