Abstract

Micro light-emitting diode displays having colloidal or graded index quantum dot films and methods of fabricating micro light-emitting diode displays having colloidal or graded index quantum dot films are described. In an example, a micro light emitting diode pixel structure includes a plurality of micro light emitting diode devices in a dielectric layer. A transparent conducting oxide layer is above the dielectric layer. A material layer is on the transparent conducting oxide layer, the material layer having a portion with a hydrophilic surface and a portion with a hydrophobic surface, the hydrophilic surface over one of the plurality of micro light emitting diode devices. A color conversion film is on the hydrophilic surface of the material layer and over the one of the plurality of micro light emitting diode devices.
