screen touch. When there is a touch, a finger or other object will block the horizontal and vertical infrared rays passing through the position. When the touch screen scans and is convinced that one of the infrared rays is blocked, the red light is on, indicating that the infrared rays are blocked. There may be a touch, and immediately change to another Scan the coordinates again. If another infrared axis is blocked on the other axis, and the yellow light is on, it indicates that a touch was found, and the positions of the two infrared blocking tubes that were found to be blocked are reported to the host, and the position of the touch point on the screen is determined through calculation.
