<p>An infrared touch screen. The screen comprises an infrared tube array consisting of infrared tubes, and a touch detection area. The infrared tubes comprise infrared emitting tubes and infrared receiving tubes. The screen is characterized in that: the infrared tube array is arranged on two opposing sides of the touch detection area; on at least one side, the infrared tube array is formed by the infrared emitting tubes and the infrared receiving tubes in a staggered arrangement. The staggered arrangement of the present technical solution reduces interference by ambient light, improves precise positioning and accuracy.</p> |
