Flip-chip, micro-pixellated InGaN light-emitting diode arrays: attractive sources for micro-displays, colour conversion, and fluorescence detection

Abstract

Flip-chip micro-pixellated InGaN light-emitting diode (micro-LED) arrays fabricated in both matrix-addressable and individually-addressable formats were presented. Despite different addressing schemes, all these LED arrays exhibited superior device operation performance in terms of power output, emission uniformity, and current handling capability, in contrast to the top-emitting counterparts. With the aid of custom-designed driver circuitry, a wide range of promising applications have been demonstrated by using these micro-light sources including micro-display, colour conversion, and fluorescence detection.
