Do you know the concept and working principle of the infrared touch all-in-one?
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.
As the latest computer input device, the touch screen is the simplest, most convenient and natural way of human-computer interaction. It gives multimedia a new look and is an attractive new multimedia interactive device. Mainly used in public information inquiry, leadership office, industrial control, military command, electronic games, ordering songs, multimedia teaching, real estate pre-sales, etc.
So, what kinds of touch screen technology are there? What is the concept and working principle of infrared touch technology? KONWHAI Technology Editor edits your answers.
The concept and working principle of the infrared touch integrated machine:
From the technical principle to distinguish the touch screen, it can be divided into five basic categories: vector pressure sensing technology touch screen, resistance technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic wave technology touch screen.
Most of the advertising machine applications on the market have chosen infrared touch screens. Why? Since the technical level of the infrared touch screen has been matured, it can be made into a large size in terms of size, and can also be made into a small size, which is highly sensitive.
Infrared touch screen advantages:
Its touch sensitivity and touch accuracy are second only to the capacitive screen, even the pen is written without pressure, the touch does not drift, and the circle is drawn 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.
Infrared touch screen concept:
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.
Infrared touch screen works:
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. As shown in the following figure, 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.
