Abstract

The invention relates to a touch screen, in particular to an infrared touch screen. A conveniently-connected infrared touch screen comprises protective glass, an infrared transmitting device and an infrared receiving device, wherein the signal-output end of the infrared receiving device is communicated with external equipment through a USB (Universal Serial Bus) interface. Because the technical scheme is adopted, the conveniently-connected infrared touch screen has the advantages of simpleness in use, convenience in maintenance and the like, and the carrying cost can also be lowered and the carrying risk can also be reduced in the maintenance process.

Description

technical field [0001] The invention relates to a touch screen, in particular to an infrared touch screen. Background technique [0002] The infrared touch screen uses the dense infrared matrix in the X and Y directions to detect and locate the user's touch. Infrared touch screens generally install a protective glass in front of the display, and infrared emitting devices and infrared receiving devices are arranged on the four sides of the protective glass, corresponding to each other to form an infrared matrix that crosses horizontally and vertically. When the user touches the screen, the finger will block the horizontal and vertical infrared rays passing through the position, and then the position of the touch point on the screen can be judged. The protective glass, infrared emitting device, infrared receiving device and circuit board of the existing infrared touch screen are all arranged on a frame. Once this type of infrared touch screen fails, the entire frame needs to ...
