Higher resolution is the key trend for next generation TV applications. One challenge is keeping the transmittance while pixel density increases. UBplus technology using LC mixtures with negative dielectric anisotropy offers a unique solution to this challenge in a classic FFS cell layout. This paper summarizes the recent developments of liquid crystal mixtures for UBplus in terms of performance and reliability.

Premium displays that offer outstanding characteristics are becoming more important in liquid crystal display market. Globally, researchers are looking for ways to improve contrast, transmittance, viewing angle dependency, resolution and switching speed while keep the high reliability level of liquid crystal devices. UB (Ultra Bright)‐technology (UBplus and UBFFS) can increase panel transmittance by using negative dielectric anisotropy LC mixtures compared with traditional FFS Mode, supporting higher resolution devices. In this paper we demonstrate the advantage of UB‐LC technology for TV as well as IT applications and summarize the recent developments of such liquid crystal mixtures in terms of contrast, switching speed and reliability.

“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.
