qomo interactive monitor.Infrared touch screen technology is to install infrared transmitting tubes and infrared receiving tubes around the screen to form an infrared light matrix, and then continuously scan and detect in both horizontal and vertical directions, and perform coordinate positioning for position judgment when the touching object blocks infrared light. technology. The display is generally mounted in front of a circuit board frame, the corresponding infrared emission tube mounting infrared receiving tube and four sides of the circuit board, as the following figure , the infrared emission is white, black for the infrared receiving tube , through the circuit The infrared transmitting tube is driven to emit infrared light, and the receiving tube positioned oppositely receives the infrared light signal. When the user touches the screen, the finger will block the outside line passing through the position in the horizontal and vertical directions. The change of the light signal causes the electrical signal output by the photodetection circuit to change. The position of the touch point on the screen can be located by processing the electrical signal. Any touch object that is opaque to infrared light can block infrared light to achieve touch positioning. This article from the infrared supply network provides
