Optically driven liquid crystal displays (ODLCDs) realizes their display function by tuning the easy axis of liquid crystal (LC) molecules under polarized blue light, which has been utilized in some optical devices due to its advantages of ultra-low power consumption. However, a big issue arises in response time, i.e., the rewriting time of the ODLCD. The rewriting time of ODLCD samples was studied. Rotational viscosity plays a very important role for decreasing the rewriting time of the ODLCD. The operating temperature was changed from room temperature to nearly clearing point, the rewriting time decreased a lot as the rotational viscosity decreased for the five different kinds of the LCs. The rewriting time can be decreased from 5.2 s to 0.2 s around 25 times for the LC N4.

工作温度对光驱动液晶显示器响应时间的影响

光驱动液晶显示器（ODLCD）通过在偏振蓝光下调节液晶（LC）分子的易轴来实现其显示功能，由于其超低功耗的优势，这种液晶已在某些光学设备中得到利用。但是，响应时间，即ODLCD的重写时间，出现了一个大问题。研究了ODLCD样品的重写时间。旋转粘度对于减少ODLCD的重写时间起着非常重要的作用。在5种不同的LC中，工作温度从室温变为接近清点，重写时间随着旋转粘度的降低而大大减少。对于LC N4，重写时间可以从5.2 s减少到0.2 s，约为25倍。
