touch screen display 48

touch screen display 48.The voltage fields in the X and Y directions are applied to the same layer of transparent conductive layer ITO, and the outermost nickel-gold conductive layer (nickel-gold conductive layer: the outer conductive layer of a five-wire resistive touch screen uses a ductile nickel-gold coating Layer material, because the outer conductive layer is frequently touched, the ductility of nickel-gold material is used to extend the service life.) It is only used as a pure conductor. When touched, the X-axis and Y-axis voltage values ??of the contact point are time-divided. Method to measure the position of the touch point. The inner layer of ITO requires four leads, and the outer layer has five leads. Capacitive screen The surface of the capacitive screen is coated with a transparent conductive layer of ITO, and the voltage is connected to the four corners. The tiny DC current spreading portion forms a uniform electric field on the surface of the screen. When the screen is touched by hand, the human body acts as a coupling capacitor, and the current is collected from the four corners of the screen to form a coupling The other pole of the capacitor calculates the coordinates of the touch by the controller calculating the relative distance of the current to the touch position. Infrared screen The infrared touch screen uses the dense infrared matrix in the X and Y directions to detect and locate the user's touch. The infrared touch screen is equipped with a circuit board frame on the front of the display. The circuit board arranges infrared transmitting tubes and infrared receiving tubes on the four sides of the screen, one by one to form a horizontal and vertical infrared matrix. When the user touches the screen, the finger blocks the two infrared rays passing through the position, so that the position of the touch point on the screen can be determined. Any touch object can change the infrared on the contact to realize touch screen operation.
