27 inch touch screen monitors

27 inch touch screen monitors.In operation , the controller of the microprocessor ( the ARM7 or other) controls the driving circuit ( shift latch) are sequentially turned on and the infrared emission of the same when addressed by a respective infrared receiver address and data lines. When there is a touch, a finger or other object will block the horizontal and vertical infrared rays passing through the position. When the microprocessor scans and checks, it will find that the infrared rays are blocked. It is judged that there may be a touch, and it will immediately change to another coordinate and scan again. It was found that there was also an infrared block on the other axis, indicating that a touch was found, and the positions of the two infrared pair tubes that were found to be blocked were reported to the host, and the position of the touch point on the screen was determined through calculation. Its control principle is shown in Figure 1.
