Resistive touch screen is through the external force on the surface of the touch screen, so that the upper and lower layers of the touch screen contact each other to form a circuit, so as to determine the touch position and realize the touch function. Therefore, any object that is not sharp and has a certain strength can make the resistive touch screen work, including fingers.
Obtouch Resistive Touch Panel – 4-wire touch panel realizes the touch function by confirming a coordinate position on the X and Y axes through the contact between ITO film and ITO glass. Because of its special touch principle and strong stability, 4-wire resistive touch screen is still used in a wide range of industrial control products. It should be noted that once the touch screen is broken, 4-wire resistive touch screen will lose its function.
