Precautions for use of industrial LCD
Date:2019-09-05
As a kind of expensive electronic product equipment, industrial LCD should pay attention to many safety factors in the use process to ensure the normal work of the industrial LCD. Because the industrial LCD is fragile and vulnerable, the safety protection of the mold is very important
1. Industrial liquid crystal display (LCD) shall prevent DC voltage application:
1. The smaller the DC component of the driving voltage, the better. The maximum voltage should not exceed 50 mV. If too much DC component is applied for a long time, electrolysis and electrode aging will occur, thus reducing the service life.
2. Industrial liquid crystal display (LCD) shall be protected from ultraviolet radiation
1. Avoid direct sunlight for a long time when using. Liquid crystal and polarizer are organic substances, which will cause photochemical reaction and deterioration under ultraviolet irradiation. Therefore, when assembling liquid crystal display devices, it is necessary to consider whether it is necessary to install anti ultraviolet filters or other anti ultraviolet methods in front of them according to their use and use environment.
3. Industrial liquid crystal display (LCD) shall be protected from the erosion of harmful gases
Liquid crystal and polarizer are organic substances, which have chemical reaction and deterioration in the environment of harmful gas. Therefore, the isolation measures of harmful gas should be taken in use. In addition, after the whole machine is assembled, it should not be sealed and stored for a long time, so as to prevent the excessive concentration of chemical gas produced by plastic shell and circuit board cleaning agent from damaging liquid crystal and polarizer.
4. The industrial liquid crystal display is made of two pieces of glass, only 5 ~ 10um between them, very thin. Moreover, the inner surface of the glass is also coated with a layer of orientation film, which is easy to damage. So we should also pay attention to the following points: liquid crystal device surface pressure should not
