The infrared touch screen is provided with a circuit board outer frame in front of the display, and the circuit board is provided with infrared transmitting tubes and infrared receiving tubes on four sides of the screen, so that infrared matrixes which are crossed transversely and vertically are formed in a one-to-one correspondence mode. When a finger touches the screen, two infrared rays in the transverse direction and the vertical direction passing through the position can be blocked, so that the coordinate position of a touch point on the screen can be judged. Any non-transparent object can change the infrared ray on the touch point to realize the touch screen operation.
