8.2: Development of Tandem White Architecture for Large‐Sized AMOLED Displays with Wide Color Gamut

Abstract

Abstract In this paper, we discuss the development of tandem white OLED structures optimized for TV‐Sized full‐color AMOLED displays using an RGBW pixel format. A highly efficient (24 cd/A) and stable tandem white OLED, with color optimized for the display white point (D65), has been developed that enables low power consumption (<50 W for a 32″ TV), as well as long lifetime (>100K h). Additionally, we describe the development of new color filters that deliver 102% NTSC ratio when combined with the tandem white OLEDs.
