Also as a display, what is the difference between an industrial display and an ordinary display? Why can't the industrial display be replaced with a cheaper ordinary display? This should start from the characteristics of the two.
When a display forms a closed-circuit monitoring system, it usually needs to be continuously powered on 24 hours a day, 365 days a year, and the application environment of some displays may be harsh, which requires higher reliability and stability of the display. Compared with industrial displays, in terms of design, the display’s current, power consumption, temperature, resistance to electrical interference, electrical shock capability and margin, and mean time between failures are much greater than that of ordinary liquid crystal displays. At the same time, industrial displays must Use a fully shielded metal shell to ensure electromagnetic compatibility and interference performance; in the selection of components, the withstand voltage, current, temperature, humidity and other characteristics of the components used in the display are higher than those used in the TV. In terms of installation and debugging, especially the process requirements of components and the aging of the whole machine, the requirements for industrial displays are also higher. The aging of the whole machine during the manufacture of ordinary liquid crystal displays is usually about 8 hours of power on the assembly line at room temperature. The aging of the machine needs to be energized and aged for more than 24 hours on the aging assembly line in a high temperature and high humidity closed environment to ensure the stability of the whole machine.
Industrial displays are produced to adapt to complex working environments such as high temperature, high pressure and humidity. They cannot be replaced by ordinary displays, and ordinary displays cannot withstand the test of this environment.
