In an integrated multi-color micro-LED display panel, arrays of different color micro LEDs are integrated with corresponding driver circuitry. Some colors of micro LEDs are inorganic micro LEDs, and other colors are organic micro LEDs. Inorganic versus organic can be selected on the basis of efficiency, for example using inorganic micro LEDs for blue pixels and organic micro LEDs for red and green pixels. In one approach, an array of pixel drivers is first fabricated on a supporting substrate. Multiple strata of micro LEDs are then stacked on top of the base substrate. The strata containing inorganic micro LEDs are fabricated first, with one color per stratum. A single stratum containing all of the organic micro LEDs is then fabricated at the top of the stack.
