Three-wavelength white organic light-emitting diodes on silicon for high luminance and color gamut microdisplays

•We developed a high-luminance, low-voltage, three-wavelength, top-emitting white organic light-emitting diode (WOLED) using a silicon substrate.•The device exhibited luminance of ∼4,200 cd/m2 at 3.3 V, and the maximum luminance reached 170,000 cd/m2 at 11.4 V.•Red, green, and blue color filters were deposited onto the WOLED after the thin-film encapsulation process to verify feasibility of the device for full-color microdisplay applications.•The color gamut of the developed WOLED with color filters was 136% compared to sRGB.
