Today LCD TVs are drived by 120 Hz speed, but blue phase liquid crystal mode LCD panel response time are short so that it is no need to over drive, which can achieve 240 Hz even more high-speed driving. And blue phase mode displays have no need with the membrane but ultra-fast response time and so on. However, the problems of blue phase liquid crystal are: (1) shortage of the blue phase temperature, (2) high working voltage. Therefore, in the literature [3] used the polymer to stabilize the blue phase liquid crystal that can effectively expand the blue phase temperature, so this study uses of polymer network structure to change the temperature and working voltage of blue phase liquid crystal with chiral materials.
