In the low temperature environment, liquid crystal molecules movement ability is reduced, resulting in a reduction in the display response speed, which may directly affect the real-time control and information reading of industrial equipment. In cold regions or cold chain transportation and other scenarios, the LCD Response Delay may trigger operation misjudgment or even safety accidents.
Solutions for LCD Response Delay of liquid crystal in low temperature?
1. Integration of local heating module
Local heating, the heating element and display precision fit, and to avoid uneven temperature distribution caused by local aging or high energy consumption. This not only reduces LCDresponse delay, directly enhance the liquid crystal layer temperature to the working threshold, and response speed recovery efficiency of more than 80%, applicable to most industrial displays.
2. Driving voltage dynamic adjustment
Driving voltage adjustments needs for different liquid crystal materials to establish voltage and temperature compensation model, to avoid over-voltage drive caused by the screen residual shadow. The advantage of this method is that no hardware changes that can solve the LCD response delay, through software upgrades can achieve delay optimization, the cost is lower than the physical heating scheme.
3. Low temperature liquid crystal material replacement
Replacement of liquid crystal materials need to be compatible with the existing packaging process, and need to verify the stability of high and low temperature cycle test. This method can fundamentally eliminate the bottleneck of low-temperature performance, solve the LCD response delay, and is suitable for long-term exposure to -40 ℃ below the polar research equipment.
4. Dynamic image preloading algorithm
The difficulty of the dynamic image preloading algorithm is that it needs to calibrate the prediction parameters in real time through the temperature sensor, and the algorithm needs to be adapted to a variety of display content types. However, the advantage is that by predicting the user’s operation and rendering the screen in advance to LCD response delay, the sense of visual delay is reduced by more than 60%, and it is suitable for touch control devices with frequent interaction.
