System considerations for RGBW OLED displays

Abstract

Abstract— The fabrication of full‐color RGBW OLED displays using a white emitter with RGB color filters has been previously described. This paper discusses the effect of several display‐system factors on the important RGBW OLED display performance attributes of power consumption, lifetime, and perceived image quality. These display‐system factors include the spectrum of the white OLED, the white OLED structure, the color‐filter selection, the subpixel aperture ratios, and the pixel arrangement (including sub‐sampling).
