12 inch touch screen usb

12 inch touch screen usb.A resistive touch screen is a sensor that converts the physical location of a touch point (X, Y) in a rectangular area into a voltage that represents the X and Y coordinates. Many LCD modules use resistive touch screens. This screen can use four-, five-, seven-, or eight-wires to generate a screen bias voltage and read back the voltage at the touch point. The resistive touch screen basically has a structure of a thin film and glass, and an adjacent surface of the thin film and the glass is coated with an ITO (nano-indium tin metal oxide) coating. ITO has good conductivity and transparency. When touch operation is performed, the ITO on the lower layer of the film will contact the ITO on the upper layer of the glass, and the corresponding electric signal will be sent out through the sensor, which will be sent to the processor through the conversion circuit, which will be converted into the X and Y values ??on the screen by calculation, and the completion point The selected action is displayed on the screen.
