interactive screen touch panel

interactive screen touch panel.( 1 ) Surface capacitive touch screen: The surface capacitive touch screen consists of an analog sensor and a two-way intelligent controller. The analog sensor is a 4- layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO conductive coating. The outermost layer is only 0.001 5 mm thick silica glass, forming a solid and durable protective layer. The interlayer ITO coating is used as the working surface, and an electrode is drawn from each corner, and the inner layer of ITO is used as a shielding layer to ensure a good working environment. When the touch screen works, the electrodes on the edge of the sensor generate a distributed voltage field. Due to the existence of the electric field in the human body, a coupling capacitor will be formed between the finger and the working surface of the touch screen when the screen is touched, because high frequency signals are connected to the working surface. , then sucked finger a small current, respectively, from the touch panel 4 flows out of the electrode on the corner. In theory, the current flowing through the four electrodes and the finger is proportional to the distance from the four corners, by this controller . 4 full precision current proportional calculation, so that the position of the touch point can be obtained.
