The wide temperature LCD display screen will also be affected by the high temperature in the working environment. Although the wide temperature LCD display screen has a wider working temperature range than the ordinary LCD display screen (such as -20℃ to 70℃, or -30℃ to 80℃, etc.), it does not mean that it can work for a long time in extreme high temperature without being affected. The specific impact of high temperature on the wide temperature LCD display screen Degradation of display effect: High temperature will cause the flow speed of liquid crystal molecules to accelerate, thereby affecting the color and brightness of the displayed pattern or text, making the display effect worse. High temperature will also reduce the quantum efficiency of the phosphor, resulting in a decrease in the brightness of the LCD screen, further affecting the display effect. Damage to the physical structure: High temperature may cause the packaging materials (such as silica gel) of the LCD display screen to denature, accelerate […]
