Abstract
A passive-matrix monolithic full-color InGaN light emitting diode (LED) microdisplay with 40 × 40 full-color pixels is demonstrated. Each full-color pixel consists of red, green, and blue (RGB) subpixels that have a pitch size of 40 μm × 120 μm. The full-color microdisplay is monolithically fabricated on blue/green dual-wavelength LED epilayers, using red quantum dot photoresist as a color converter. Pure RGB emission and a wide color gamut are achieved, as shown by electroluminescence spectra. Full-color patterns with controllable grayscale and color mixing can be clearly rendered driven by a full-color microdisplay controller, indicating tremendous potential of this novel approach for full-color LED microdisplays in the future.
