The demand for 55-inch touch all-in-one machines in the market is particularly significant. So, how to choose a suitable industrial touch all-in-one machine? The editor of Siyuan introduces the advantages and disadvantages and applicable conditions of various touch screens.
One, industrial touch all-in-one touch screen type
1. Surface acoustic wave touch screen: pure glass material: good light transmission, long service life, good scratch resistance, suitable for all kinds of public places. But it is afraid of long-term accumulation of dust and oil pollution, so the requirements for the environment are higher.
2. Infrared induction touch screen: The resolution is low, but it is not interfered by current, voltage and static electricity, and is suitable for some harsh environmental conditions; it is suitable for various public places and offices without infrared and strong light interference and the requirements are not very precise Industrial control site;
3. Capacitive sensing touch screen: Since the capacitance changes with temperature, humidity or grounding conditions, its stability is poor and it tends to drift. Afraid of electromagnetic field interference and drift, it is not easy to use in industrial control places and places with interference. It can be used for public information query that requires less precision; it needs frequent calibration and positioning.
4. Four-wire resistive touch screen: It is not afraid of dust, oil pollution and radio and television interference. The main defect is the fear of scratches. Applicable to public places with fixed users, such as industrial control sites, offices, homes, etc.;
5. Five-wire resistive touch screen: good sensitivity and light transmittance, long service life, not afraid of dust, oil pollution and radio and television interference, suitable for all kinds of public places, especially for precision industrial control sites.
Second, understand the quality of industrial touch all-in-one
1. The system on which the product is installed
The stability of the system determines the effect of equipment operation, and different industries have different requirements for it. Obviously, in the system operation of my country's industrial-grade display equipment, consumers have a variety of development software options, and they want to quickly carry this kind of development information and ensure better operating results, so we must Understand this kind of software system, and use it as a core reference.
2. Material and structure used in the product
The structure of the product and the materials used will directly affect the service life of our products. For industrial displays, in order to ensure stable application in the working environment, it is indispensable to use more durable materials and better In order to ensure the stability of the operation, when we choose industrial displays, we must also have a certain understanding of them.
In general, the choice of the industrial touch all-in-one machine whether it is 55 inches or other sizes is mainly based on the user's use environment. Industrial displays need to know the system they are equipped with and the materials and structures used, and comprehensive considerations can be selected. The most cost-effective product.
