In fact, this question is a bit ambiguous, we know, for example, the working range of wide temperature is -20-70 degrees, then first of all, in an environment below minus 20 degrees and above 70 degrees, the LCD screen theoretically cannot work, if the temperature has not reached 70 degrees and minus 20 degrees, but it is very close, it can be said to be the limit temperature, then the LCD screen can still work normally?

From the principle of the LCD screen, it is very easy to explain, the reason why the LCD screen can display various patterns or pen segments is because the liquid crystal in the LCD box is working, and the LCD screen, as the name suggests, is liquid, must be affected by the environment, when the temperature is high, the liquid crystal will heat up, the flow speed will be accelerated, and the feedback on the display is that the color becomes very deep; When the temperature is low, the liquid crystal will begin to crystallize, the flow will slow down, and the color on the display will become very light, not that it cannot be displayed normally, but that the normal time of the display is much slower than that at room temperature.

In this way, everyone should be able to understand it, the working temperature is from the LCD screen, it just means that it can work in this temperature range, and it will not be displayed or refreshed due to environmental factors.

In this way, taking the wide temperature LCD screen as an example, starting from minus 5 degrees and minus 50 degrees, the display rate will begin to change, to minus 20 degrees and minus 70 degrees, it will reach the limit temperature, and the feedback to the screen is no display or a pitch black state, it is already unusable, so Yilikai LCD usually recommends that customers, if the actual use temperature is close to the limit temperature, then be sure to choose a wider temperature range of LCD screen to use.

Well, the above is the introduction of how to classify the working temperature of LCD LCD screen, have you learned?
