Capacitive Touch screen CTP (Capacity 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.
Capacitive touch screen is very different with traditional resistive touch screen. When the resistive touch screen works, you can only judge a touch point. And if there are two or more touch points, you can not make the right judgments. So the resistive touch screen applies only to judge a few simple actions such as click, drag and drop. The capacitive multi-touch screen can decompose the user's touch into colleting multi-point signal and determining the significance of the signals, and complete the judgments of complex action. Moreover, you can feel it when you lightly touch the projected capacitive touch sensor panel. Better durability, more than 90% light transmission rate, high transparency than the traditional resistive touch screen are the advantages of our products.
