Generally speaking, international touch screens can only be used for products of the same brand, and even products of the same brand and different series cannot adapt to other brands of industrial touch screen equipment on the market.
1. Applicability of specifications and models
Generally speaking, the scope of application of international touch screens is much narrower than that of products with prices close to the common people. Generally, they can only be used for products of the same brand. Even products of the same brand and different series cannot adapt to other brands of industrial touch screen equipment on the market. Therefore, try to choose adaptable equipment, check whether the industrial display has relevant domestic and foreign certifications, it is recommended to try it out or find professionals and equipment to test key performance.
2. Compare the transparency of the screen
Screen transparency directly affects the visual effect of industrial displays. Generally speaking, transparency refers to the average transparency in the picture, of course, the higher the better.
3. Compare the reflection performance of the screen
Specular reflection will cause light and shadow behind overlapping images, such as human shadows, windows, lights, etc. Reflection is a negative impact encountered in the use of industrial displays. The smaller the better, it will have a certain impact on the browsing speed of users. Touch screens are absolutely The coordinate system, directly select points from the screen, is essentially different from relative positioning systems such as the mouse, and is intuitive at one time.
4. Consider absolute coordinates
No matter under what circumstances, the output data of the same point have sufficient stability. If it is unstable, the touch screen cannot guarantee accurate positioning, and the contacts are inaccurate. This is the most feared problem of industrial touch screens.
The selection and correct positioning of inductive touch is realized through sensors in different parts. Even some industrial touch screens have a complete set of sensors. The positioning principles and sensing technologies of different products determine the response speed, reliability and stability of industrial touch screens and service life.
