Everyone knows that the working temperature of conventional TFT LCD screen is -20 to 70 degrees, the storage temperature is -30 to 80 degrees, and the working temperature of wide temperature TFT LCD screen is -30 to 85 degrees. In order to pursue a wider working temperature, some customers will test whether TFT LCD screen can work normally under extreme temperature. Many customers find that the words displayed on the LCD screen become very light when the temperature is very low, and the words become very dark when the temperature is very high. What's going on?
In fact, it is easy to explain from the principle of LCD screen. The reason why LCD screen can display various patterns or pen segments is that the liquid crystal in the liquid crystal box is working, and the liquid crystal, as the name implies, is liquid. It must be affected by the environment. When the temperature is high, the liquid crystal will heat up and flow faster. The feedback on the display is that the color becomes very dark.
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. It is not that it cannot display normally, but that the time to display normally is much slower than at normal temperature.Everyone should understand this. For LCD screens, the operating temperature only means that it can work within this temperature range, and it will not fail to display or refresh due to environmental factors.
Shenzhen Hongjia Technology has many display screens that can meet the operating temperature of -40 to 85 degrees, which are suitable for customers with higher temperature requirements. Customers are welcome to email us for consultation.
