1. 실제 사용에서 예산을 고려
At present, there are many brands of industrial liquid crystal displays on the market, which are roughly divided into three grades: high, medium and low. Many of them are international first-line brands with good quality, and of course there are domestic brands with affordable prices. If you have enough budget, you might as well consider big brands and choose international first-line high-quality products.
The reality is often that the budget is very tight. If the required industrial display is only used as a display and is not often used for control input, then you can choose some relatively cheap domestic brands; if you do not have a relatively abundant budget, you need to use the industrial touch display frequently. When the input control is used, then the brand of the middle grade can be considered. Guangzhou Suosu Electronic Technology Co., Ltd. is a research and development enterprise that produces middle and high-end industrial display screens.
2. Applicability of specifications and models
Generally speaking, the scope of application of touch screens of international first-line brands is much narrower than that of products with affordable prices. Generally, they can only be used for products of the same brand, and even products of different series of the same brand cannot adapt to other brands on the market. Industrial touch screen equipment, so try to choose equipment with strong adaptability.
3. Product performance and quality certification
Check whether the industrial LCD display has relevant certifications at home and abroad. It is recommended to try it out or find professionals and equipment to test the key performance.
4. Compare the transparency of the screen
Screen transparency directly affects the visual effect of industrial displays. Usually, the transparency refers to the average transparency in the picture. Naturally, the higher the better.
5. Compare the reflective performance of the screen
Due to specular reflection, the image will overlap the light and shadow behind it, such as human shadows, windows, lights, etc. Reflection is a negative effect encountered in the use of industrial displays. The smaller the better, it will have a certain impact on the user's browsing speed. The touch screen belongs to the absolute coordinate system, which directly selects the point from the screen, which is fundamentally different from the relative positioning system such as the mouse, and has the intuitiveness in one place.
6. Consider absolute coordinates
The feature of absolute coordinate selection is that each coordinate selection has nothing to do with the previous coordinate selection. The touch screen physically belongs to an independent coordinate positioning system, and the data of each touch is converted into coordinates on the screen through calibration data. Therefore, The positioning coordinates of the touch screen are required to be stable enough for the output data of the same point under any circumstances. If it is unstable, the touch screen cannot guarantee accurate positioning. Inaccurate contact points are the most feared problem of industrial touch screens. Inductive touch selection and correct positioning are realized by sensors in different parts, and even some industrial touch screens themselves have a complete set of sensors. The positioning principle of different products and the sensing technology used determine the response speed, reliability, stability and service life of the industrial touch screen.
Only by considering the actual needs and the characteristics of the industrial LCD, and comparing and contrasting each other, can you choose the equipment you are satisfied with.
