The concept and working principle of infrared touch one machine
Touch screen, also known as "touch screen" and "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When touched on the on-screen graphic button, the touch feedback system on the screen can be A variety of linking devices are driven according to a pre-programmed program, which can be used to replace the mechanical button panel and to create a live sound and video effect through the liquid crystal display screen.
The variety of touch screens is single, but most of them use infrared touch screens under the use of advertising machines. Why? Since the technical level of the infrared touch screen has been very mature and fluctuating, it can be made into a large size in size, and can also be made into a small size, and the sensitivity is great.
Infrared touch one machine touch sensitivity and touch accuracy is second only to the capacitive screen, even pen writing without pressure, touch does not drift, draw a circle from time to time. Its use is minimally affected by the environment, and it is not afraid of wind and rain, and is not affected by light. Moreover, the infrared touch screen can achieve true multi-touch, and the application is not limited by the touch object.
The concept and working principle of infrared touch integrated machine:
The concept of infrared touch one machine:
The infrared technology touch screen is composed of an infrared emitting and receiving sensing component mounted on the outer frame of the touch screen, and constitutes an infrared detecting net on the exterior of the screen, and any touch object can change the infrared rays on the contact to complete the touch screen operation.
The infrared touch screen is similar in principle to the external acoustic wave touch, which uses infrared emission and receiving sensing components. These components form an infrared detection net on the outside of the screen, and the touch-operated object (such as a finger) can change the infrared rays of the electric shock, and is converted into the coordinate position of the touch to complete the operation. In the infrared touch screen, the circuit board arranged on the four sides of the screen is provided with an infrared transmitting tube and an infrared receiving tube, corresponding to an infrared matrix interposed vertically and vertically.
The working principle of infrared touch one machine:
The infrared touch screen is an infrared matrix densely placed in the X and Y directions in front of the screen. After continuous scanning, the infrared rays can be detected by the object and the user's touch is positioned. The touch screen is equipped with an outer frame at the back of the display, and a circuit board is designed in the outer frame, so that the infrared emitting tube and the infrared receiving tube are arranged on four sides of the screen, and the infrared matrix interspersed vertically and vertically is formed one by one.
After every scan, if all the infrared tubes are accessible, the green light is on, indicating that everything is normal. When there is a touch, the finger or other object will block the horizontal and vertical infrared rays passing through the position. When the touch screen scans and finds that there is an infrared light blocked, the red light is on, indicating that the infrared light is blocked, the touch can be touched, and the other is immediately switched to another The coordinates are re-scanned. If another axis is found, there is also an infrared block, and the yellow light is on, indicating that the touch is detected, and the status of the two infrared traps that are found to be blocked is reported to the host, and the position of the touch point on the screen is determined through calculation.
