We are generally divided into three grades: military, industrial and commercial military equipment such as missiles, satellites, tanks and aircraft carriers. Any part of the electronic components in the aircraft carrier is the most advanced, leading industrial class for 10 years, leading commercial class for about 20 years, the most expensive, the highest precision industrial grade-a little lower than the military grade grade, followed by the price.
Precision is the second commercial level-the kind of computer, mobile phone you can see on the market is basically commercial, for example, the chip made by Microsoft is the cheapest and most common in the commercial class, the cheapest and most common, the most practical working temperature range is 0 ℃ ~ 70 ℃, the industrial grade is-40 ℃ ~ 85 ℃, and the military grade is-55 ℃ ~ 150 ℃. In addition, some devices have an industrial grade of-40 ℃ ~ 125 ℃.
But the temperature of our liquid crystal module is divided into two categories, one is working temperature, the other is storage temperature. In general, the operating temperature of liquid crystal module is-20 °to 70 °, and the storage temperature is-30 °to 80 °.
