Problems solved by technology

[0003] The principle of the infrared touch screen is to use the dense infrared rays in the X and Y directions to detect and locate the touch operation, but the existing infrared touch screen will have dead spots or occlusions, resulting in the inability to receive infrared rays, which wastes time and is inefficient.

Abstract

The invention discloses an infrared touch module, and relates to the technical field of infrared touch. An infrared emission unit comprises a plurality of infrared emitters which are horizontally arranged; infrared rays emitted from the inferred emitters correspond to infrared reflectors which are horizontally arranged; the infrared reflectors downwards incline for 30-60 degrees and leftwards incline for 30-60 degrees; infrared rays reflected by the infrared reflectors are received by a first infrared receiver arranged on the upper side of the infrared emitter; the first infrared receiver is provided with a reflection lens; the reflection lens is leftwards aslant arranged at an angle of 30-60 degrees; and infrared rays reflected by the reflection lens are received by a second infrared receiver arranged on the upper side of the infrared reflector. By use of the infrared touch module, no-dead-point and blocking type emission and receiving can be realized, the efficiency of the infrared touch module is high, and a coverage range is wide.

Description

Technical field: [0001] The invention relates to an infrared touch module, which belongs to the technical field of infrared touch. Background technique: [0002] With the rapid development of display technology, touch screens have gradually spread in people's lives. At present, touch screens can be classified according to principles into: resistive touch screens, capacitive touch screens, infrared touch screens, piezoelectric touch screens, and surface acoustic wave touch screens. Among them, the infrared touch screen has the characteristics of high stability, high adaptability, long life, and good characteristics, and has received more and more attention and application. [0003] The principle of the infrared touch screen is to use the dense infrared rays in the X and Y directions to detect and locate the touch operation, but the existing infrared touch screen will have dead spots or occlusions, resulting in the inability to receive infrared rays, which wastes time and is ...
