Problems solved by technology

However, blue-phase liquid crystals still have shortcomings such as narrow temperature range and high driving voltage of blue-phase liquid crystals at this stage. Most importantly, it is impossible to screen out in large quantities whether blue-phase phases will appear in the selected system.

In addition, the blue phase liquid crystal mainly has the problem of narrow temperature range, but it is very time-consuming to detect its temperature range, and because it is very sensitive to external conditions, it is easy to cause errors in the data measured by different batches

[0003] At the same time, the electro-optical properties of blue phase liquid crystals are also measured slowly, and the data is unstable due to repeated driving that will destroy its phase state, which will cause data fluctuations for the same batch of samples

[0004] Most of the existing liquid crystal detection technologies are single-channel detection, the test efficiency is low, and it is impossible to complete the screening research of large-scale materials
