Abstract

AbstractElectro‐optical switching of the liquid crystalline Blue Phase exhibits extremely fast response times. However, the unstabilized Blue Phase is characterized by a rather narrow temperature range on the order of a few K. For display applications the operating temperature range needs to be increased. One very promising way is to broaden the stable temperature range by polymer‐stabilization of the Blue Phase. Successful stabilization is achieved by proper material selection/matching of reactive mesogens (RMs) and the chiral host. One prerequisite for application in display manufacturing is excellent UV and heat stability as well as good processability. Improvements in relevant performance parameters will be presented and discussed.
