To measure the quality of a touch screen must be comprehensively considered from many aspects. You can't just look at one aspect of performance, but how can you quickly distinguish a good infrared touch screen as a superior quality touch screen under many performance parameters? We can understand from the following touch screen characteristics.
First, touch the surface of the screen to distinguish, the surface should be uncoated, so that the brightness will not be reduced. Brightness determines the stability of performance when applied in a field with changing light. If the brightness suddenly changes when the light is intensified, it will be very troublesome and inconvenient in application.
The second is the high light resistance of the surface. If the anti-light performance can achieve perfect work under direct sunlight environment with illuminance>100000 LUX, the infrared touch screen produced by Zhengda Yingtuo can still work perfectly under direct sunlight environment with illuminance>100000 LUX.
In the high-definition era, a good infrared touch screen must achieve a high resolution. Therefore, if the touch screen achieves a high resolution of 4096 x 4096, it can be handy in some applications that require high definition. Then it comes to the response speed of the touch screen. The response speed must be fast. The response speed is less than 16ms and can be touched with any opaque object with a diameter greater than 5mm.
Then when it comes to the selection of touch screen materials, glass selection is the key, anti-riot, non-wear, and toughened glass.
The surface of the touch screen is sealed with a waterproof rating of IP65 (optional), so that it can be operated in harsh environments: such as rain, snow, and fog.
The last good infrared touch screen can work in various indoor and outdoor environments
For internal structure, there is a built-in control card, no additional control card is needed, the maximum operating temperature can reach from -40 degrees to 70 degrees, it can achieve intelligent fault-tolerant design, strong stability, long life, single location click>de 60 de milioane de ori
Summarize that a good infrared touch screen must have the following characteristics:
-No coating, no brightness reduction
-High light resistance, it can still work perfectly under direct sunlight environment with illuminance>100000 LUX
-High resolution 4096 x 4096

What is an infrared touch screen
Principle of infrared touch screen
The infrared touch screen uses the infrared matrix densely distributed in the X and Y directions to detect and locate the user's touch. The infrared touch screen is equipped with a circuit board outer frame in front of the display, and the circuit board is arranged with infrared emitting tubes and infrared receiving tubes on the four sides of the screen, one by one corresponding to a horizontal and vertical cross infrared matrix. When the user touches the screen, the finger will block the horizontal and vertical two infrared rays passing through the position, so the position of the touch point on the screen can be judged. The external touch screen is a highly integrated electronic circuit integration product. The infrared touch screen contains a complete integrated control circuit, a set of high-precision, anti-interference infrared transmitting tubes and a set of infrared receiving tubes, which are installed in two opposite directions on a highly integrated circuit board to form an invisible infrared. Raster. The intelligent control system embedded in the control circuit continuously pulses the diode to form an infrared polarized beam grid. When a touching object such as a finger enters the grating, the light beam is blocked. The intelligent control system will detect the change in light loss and transmit a signal to the control system to confirm the X-axis and Y-axis coordinate values.
