INFRARED TOUCH SCREEN AND DISPLAY DEVICE

摘要

An infrared touch screen in of a quadrilateral shape is disclosed. The infrared touch screen is provided with a plurality of light sources at its first side and provided with a plurality of first detecting units at its second side opposite to the first side, and is provided with a plurality of second detecting units respectively at its third side and its fourth side which are opposite to each other, and the first detecting units and the second detecting unit are all configured to partly receive and partly reflect the infrared light emitted by the light sources, so that the infrared light emitted by the light sources can form criss-crossing light paths. The infrared touch screen achieves lowered power consumption and improved touch performance.
