1. A display system comprising:
micro light emitting diodes on a top surface of a buffer layer;
at least one passivation or planarization layer covering the micro light emitting diodes;
a reflective layer covering the at least one passivation or planarization layer coupling light from the micro light emitting diodes to the buffer layer; and
a color conversion layer or a color filter layer contacting a bottom surface of the buffer layer, opposite from the top surface of the buffer layer with the micro light emitting diodes.
