White-emitting OLED devices in an RGBW format with microelement white subpizels
We describe the use of a white subpixel made up of a combination of differently-tuned microelements and demonstrate how such an approach can produce white light with good on-axis color (even for top- emitting microcavity architectures) and acceptably small color shift with viewing angle. By carefully tuning the color and areas of each of the microelements in the white subpixel, we can trade off between better on-axis color, less color change with angle, and higher efficiency. Furthermore, we demonstrate that an RGBW top-emitter microcavity device with a microelement white subpixel can achieve an increase in both power efficiency and color gamut relative to a conventional RGBW bottom-emitter nonmicrocavity device.
