Kyunghee University is a technology that improves the performance of liquid crystal lasers expected as light sources of next-generation holographic displays by a joint research team of Professor Choi Seok-won of the Department of Information and Electronic Materials Engineering, Kyunghee University, and Professor Song Myung-hoon of the Department of Materials Science and Engineering, Ulsan University of Science and Technology, who are participating in the BK21 Plus project team for next-generation display materials. It was announced on the 7th that it has developed.

The blue phase, which the research team applied the technology to, is attracting attention as a next-generation liquid crystal material that can increase production efficiency due to its simpler process than the previously commercialized nematic liquid crystal, but it has a narrow temperature range and difficult to obtain uniform alignment. Had a hard time in.

The research team developed a technology that can maintain a uniform liquid crystal state even in a wide temperature range with a blue phase, so that a blue phase liquid crystal laser can be used with only a third of the energy compared to the previous one.

The research results will be published on the cover of the June 7th,’Journal of Materials Chemistry C’, a journal in the field of optical and electronic materials of the’Royal Society of Chemistry’. The results of basic research were published in the material field journal’Advanced Materials’ in 2013.
