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.

We have developed a new liquid crystal display mode UV2A II which is suitable for a large screen 8K display and commercialized as the 80” 8K TV. UV2A II has brought large superiority that are 1.3 times higher transmittance, 35% faster response, and wider viewing angle property to compare with UV2A.
