An infrared touch frame and an infrared touch screen, the infrared touch frame comprising a housing, a circuit board, an LED lamp and a filter strip, the housing having a cavity for placing the circuit board and the LED lamp, The LED lamp is electrically connected to the circuit board, and the filter strip is matched with the housing in front of the LED lamp, wherein the thickness of the filter strip or the filter strip and the bottom surface of the LED lamp The angle of the housing is such that the light emitted by the LED lamp is refracted by the filter strip and the height of the lower surface of the bottom surface of the LED lamp is less than 4.6 mm. The infrared touch frame and the infrared touch screen change the thickness of the filter strip or the angle between the filter strip and the bottom surface of the LED lamp. According to the refraction principle, the light emitted by the LED lamp can be refracted by the filter strip. The distance from the lower surface of the bottom surface of the LED lamp is reduced, so that the user achieves a better writing effect.
