INFRARED TOUCH MODULE, INFRARED TOUCH SCREEN PANEL AND DISPLAY DEVICE

摘要

Embodiments of the invention provide an infrared touch module, an infrared touch screen panel and a display device. An infrared emitting unit is provided on two adjacent side walls of a circuit board outer frame, and an infrared receiving unit is provided on the other two adjacent side walls of the circuit board outer frame. The infrared emitting unit comprises a plurality of infrared emitters located in the same horizontal plane, and the infrared receiving unit comprises first infrared receivers for receiving infrared light rays in a horizontal direction emitted from respective infrared emitters. The infrared emitting unit further comprises a reflector located above or below each infrared emitter, for reflecting an infrared light that is emitted from each infrared emitter to the reflector along the horizontal direction; and the infrared receiving unit further comprises second infrared receivers for receiving infrared light rays in the horizontal direction reflected by the reflector.

主权项

1. An infrared touch module, comprising: a circuit board outer frame, an infrared emitting unit mounted on two adjacent side walls of the circuit board outer frame, and an infrared receiving unit mounted on the other two adjacent side walls of the circuit board outer frame; wherein,
the infrared emitting unit comprises a plurality of infrared emitters located in a same horizontal plane, the infrared receiving unit comprises a plurality of first infrared receivers corresponding to the infrared emitters one-to-one, each of which receives an infrared light ray in a horizontal direction emitted from a corresponding infrared emitter, the infrared emitting unit further comprises reflectors each located above or below each of the infrared emitters, for reflecting infrared light rays, which are emitted from the infrared emitters to the reflectors, along a horizontal direction; projections on a horizontal plane of an infrared light ray in the horizontal direction emitted by each of the infrared emitters and an infrared light ray in the horizontal direction reflected by a reflector corresponding to the infrared emitter have a set angle therebetween, and the infrared receiving unit further comprises second infrared receivers for receiving infrared light rays in the horizontal direction reflected by the reflector.
