Micro light-emitting diode displays having nanophosphors

A method of fabricating a micro light emitting diode pixel structure, the method comprising:

• providing a first wafer having a plurality of conductive interconnect structures in a first dielectric layer thereon;
• providing a second wafer having a plurality of micro light emitting diode devices in a second dielectric thereon, the plurality of micro light emitting diode devices including a first blue micro light emitting diode device, a second blue micro light emitting diode device, and a green micro light emitting diode device;
• coupling the first and second wafers to provide individual ones of the plurality of micro light emitting diode devices electrically coupled to a corresponding one of the plurality of conductive interconnect structures;
• removing the second wafer;
• forming a transparent conducting oxide layer on the plurality of micro light emitting diode devices and on the second dielectric layer;
• and
• forming a phosphor layer on the transparent conducting oxide layer at a location vertically aligned with the first blue micro light emitting diode device but not at a location vertically aligned with the second blue micro light emitting diode device.
