PATTERNED INORGANIC LED DEVICE
First Claim
1. A method of making an inorganic light-emitting diode display having a plurality of light-emitting elements comprising:
- (a) providing a substrate;
(b) forming a plurality of patterned electrodes over the substrate;
(c) forming a raised area around each patterned electrode to provide a well;
(d) depositing a dispersion containing inorganic, light-emissive core/shell nano-particles into each well;
(e) drying the dispersion to form a light-emitting layer comprising the inorganic, light-emissive core/shell nano-particles;
(f) forming an unpatterned, common electrode over the light-emitting layer; and
(e) wherein the light-emitting layer emits light by the recombination of holes and electrons supplied by the electrodes.

Abstract
A method of making an inorganic light-emitting diode display having a plurality of light-emitting elements including providing a substrate, and forming a plurality of patterned electrodes over the substrate. A raised area is formed around each patterned electrode to provide a well before depositing a dispersion containing inorganic, light-emissive core/shell nano-particles into each well. The dispersion is dried to form a light-emitting layer including the inorganic, light-emissive core/shell nano-particles. An unpatterned, common electrode is formed over the light-emitting layer. The light-emitting layer emits light by the recombination of holes and electrons supplied by the electrodes.
