The Polymer Sustained Vertically Aligned Mode (PS-VA) is an advanced future technology based on the Vertically Aligned Liquid Crystal Display (LCD) Mode. This innovative technology enables LCDs with higher transmission allowing for the use of less backlighting power for eco or green technology. The underlying key techniques are specified LC mixture development and reactive mesogen optimization. We will report the most recent material development.48.
The apparatus described serves as an electric drive of a motion picture camera. It permits, in contradistinction to other devices for the same purpose, the independent adjustment of the exposure time and the interval between the exposures. The former can be adjusted between 0.2 and 5 sec., the latter continuously over a range of a factor 5000. Two applications of this apparatus in the field of microcinematography are described, one being the determination of the falling speed of suspended colloid particles in an ultramicroscope, the other being the recording of the growth of etch figures on crystal planes produced by electrolysis.
“Energy efficiency” and “Green Technology” are currently buzzwords in the display industry. Upcoming mandatory energy regulations are further driving this development, challenging the display industry. Within this context, we would like to demonstrate the advantage of UBplus LC technology for application in TVs. UBplus technology using LC mixtures with negative dielectric anisotropy offers a unique solution to this challenge due to a high transmittance level, whilst retaining the classic FFS cell layout. This paper summarizes the recent developments of liquid crystal mixtures for UBplus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
