The LCD splicing screen flash technology is becoming more sophisticated and frequently used in various monitoring occasions, but we all know that the monitoring flash screen is usually powered on for a long time, and the operating temperature varies with the device environment, so we will assign the operating temperature requirements and color difference of the LCD splicing screen.

1、 0~40 ℃ is its working environment
In terms of geographical location or environment, the temperature difference from north to south in China is very large, and the indoor device environment is also different. Some are equipped with heaters. At this time, the edge of the LCD splicing screen should be higher than the height of the heater. Especially in winter, because the room temperature is generally low, the response of general LCD screens will slow down, This is because the thermotropic liquid crystal used in the LCD screen is derived from the change of temperature, and its photoelectric effect is controlled by temperature. If the temperature is not within the range of its application temperature, it is equivalent to getting rid of the electric field control without photoelectric effect, and various problems will occur.
2、 Color difference will also appear after long-time startup
There is a certain flash difference between the single LCD panel and the screen itself. Especially for the finished LG panel, even if the technicians adjust it later, it will be much smaller. But it is difficult to make the color of each screen flash the same. If it is used for monitoring flash, it is generally all-weather startup, In a few years, there will also be color attenuation, which is inevitable, so we should pay attention to the combination of work and rest in the use, and then extend its service life.
