The so-called touch-splicing interactive wall can be roughly referred to as: splicing screen infrared touch frame, touch screen splicing screen, splicing screen infrared frame, infrared touch screen splicing screen, liquid crystal splicing touch frame, touch splicing screen, touch screen splicing wall, splicing wall touch screen, Infrared frame splicing screen, large size splicing touch screen, large size touch screen splicing screen, DID splicing touch screen, splicing touch screen, narrow side touch screen splicing screen, narrow side splicing screen touch screen, touch splicing wall, interactive splicing touch screen, interactive touch splicing screen, The conference touches the splicing screen exhibition hall splicing screen touch screen, large-size projection splicing touch screen, etc.; many names are called according to the field application.
The touch screen splicing screen is a combination of splicing screen and touch screen. It is made up of 2 ultra-narrow splicing screens. It is made by splicing touch screen, tempered glass, splicing processor, matrix processor, HDMI splitter, multi-screen treasure, and more. The screen graphics card, audio and computer mainframe integrated interactive touch splicing screen display large-screen equipment; finally installed into a matching digital creative display software to realize human-computer interaction, auditory, visual and tactile integration in digital exhibition halls, exhibition halls, digital exhibition halls, Enterprise exhibition hall, planning exhibition hall, city planning hall, creative center, O2O experience hall, achievement exhibition hall, etc.
Infrared touch screen principle: Take the large-scale infrared multi-touch screen of Rongchuang Fangyuan as an example. Its working principle is to close the screen in front of the screen and the infrared matrix in the Y direction. Through non-stop scanning, whether infrared rays are blocked by objects and locate users Infrared touch frame, touch splicing screen. As shown in the figure below, the multi-touch screen is equipped with an outer frame on the front of the display, and a circuit board is designed in the outer frame, so that the infrared transmitting tube and the infrared receiving tube are arranged on the four sides of the screen, and the infrared matrix which is horizontally and vertically intersected is formed one by one. After each scan, if all the infrared tubes are accessible, it means that everything is normal and there is no touch. When there is a touch, the finger or other object will block the horizontal and vertical infrared rays passing through the coordinate position. When the X or Y-axis touch screen scans and finds that there is an infrared light blocked, it indicates that there may be a touch, and immediately changes to another axis coordinate. Scan, if another axis is found, there is also an infrared blocking, which means that the touch frame is found, and the position of the touch point on the screen is calculated through calculation.
