Infrared Touch Screen Technology consists of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detection network is formed. Any touched object can change the infrared rays on the contacts to realize the touch screen operation. . The realization principle of infrared touch screen is similar to that of surface acoustic wave touch, it uses infrared emitting and receiving sensing elements. These elements form an infrared detection network on the surface of the screen, and touch-operated objects (such as fingers) can change the infrared rays of the electric shock, which are then converted into the coordinate position of the touch to realize the response of the operation. On the infrared touch screen, the circuit board devices arranged on the four sides of the screen have infrared emitting tubes and infrared receiving tubes, corresponding to the formation of an infrared matrix that crosses vertically and horizontally.
So far, infrared touch screen technology has entered the fifth generation. The infrared touch screen is most suitable for the touch solution of large-size displays, and can transform large-size LCD, PDP, and rear-projection displays into a large-scale interactive display device. The infrared touch screen has a very small impact on the clarity of the picture. If the glass that protects the surface of the display is not used, the impact on the clarity of the display is reduced to zero. The user can use any object to touch the surface of the touch screen without worrying about the touch medium or coating on the surface being scratched. Infrared touch screen, computer and large-size display can form the best interactive system. It can also form a real-time, interactive and efficient conference system with the network or ordinary telephone line, which is used in KTV's on-demand system, ATM, automatic ticket vending machine, and industrial control , Medical equipment and other fields.
The conventional size is 10.427in, suitable for KIOSK, ATM, VOD, KTV song station, KTV concert station, bar, game console, industrial control, medical equipment, self-service retail, multimedia inquiry, POS machine, automatic ticketing, public Reception, government applications, securities, education, military and other fields.
Large size is 30 150in, suitable for PDP, LCD, rear projection and other large-size displays, used in video conference systems, exhibitions, electronic maps, electronic whiteboards and other fields.
