Standard (4:3)12.1" Projector Capacitive Touch Screen Frame Panel Glass Panel For Lcd

Product details 

Competitive Advantage:

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.

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.
