High-density two-color micro-LED array based on brushing-assisted micropatterning of quantum dots

We report a 17 μm-pitched two-color micro-LED array based on brushing-assisted micro- patterning of quantum dots. Filtered by an integrated distributed Bragg reflector layer, our array features bright, localized, and fast light output near 462 nm and 623 nm with low spectral and spatial crosstalk.
