Structure & Operating Principle:
Capacitive touch screen is a piece of 2 layer of compound glass with double side transparent conductive coating that conducts a continuous electrical current across the sensor.
There is electrode pattern printed along the edges distributes a low voltage filed over the conductive layer.
The human body is also an electrical device which has stored electrons and therefore also exhibits capacitance.
When a finger touches the screen and draws a minute amount of current to the point of contact ,creating a voltage drop.
The current flow from each corner is proportional to the distance to the touch point. During a touch , capacitance forms between the finger and the sensor grid. The touch location is calculated from the changing electrical characteristics of the sensor grid.
Projected Capacitive touch screen Benefits:
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. Any point can withstand more than 50 million times touch.
4. Explosion-proof and durable, scratch-resistant, anti-collision, anti-radiation within the core capacitive touch ensure stable, anti-interference ability.
5. Operating systems strong compatibility.
6. Intelligent automatic calibration, use forinternal / external variety of environments.
7.Long life, low maintenance costs.
