37‐4L: Late‐News Paper: Development of a 27‐in. 8K x 4K Liquid‐Crystal Display Utilizing an InGaZnO TFT Backplane. Issue 1 (May 2016) - Yamada, Shigeyuki
Abstract : We have successfully developed 27inch 8K4K Liquid Crystal display by utilizing BCE IGZO (Back Channel Etched InGaZnO) transistor. Its pixel density is 326ppi like smartphone, but the screen size is 27inch, middle class desktop monitor size. And its LCD panel supports 120Hz driving. BCE IGZO‐TFT realizes low resistance wiring material because of its low process temperature. Above reason, we can enlarge the screen size to desktop monitor class, remaining smartphone class fine resolution. Also this system contains HDR (High Dynamic Range) driving system, and wide color gamut, by IGZO transistor and Negative LC FFS pixel structure.
