AI Technical Summary

Problems solved by technology

In order to realize the use of cholesteric liquid crystals in flexible displays, it is necessary to encapsulate the liquid crystal molecules so that the liquid crystal molecules cannot flow freely and eliminate problems such as pressure points during flexible displays.

For this reason, the usual solution is to coat the liquid crystal with the polymer dispersed liquid crystal method, but due to the irregular polymer network formed, the resulting mechanical properties are not ideal, and there are often many problems such as high driving voltage.
