Abstract
Embodiments disclosed herein include micro light emitting device (LED) display panels and methods of forming such devices. In an embodiment, a display panel includes a display backplane substrate, a light emitting element on the display backplane, a transparent conductor over the light emitting element, a dielectric layer over the transparent conductor, and a color conversion device over the light emitting element. In an embodiment, the dielectric layer separates the transparent conductor from the color conversion device.
Claims17
A display panel, comprising:
- a display backplane substrate;
- a light emitting element on the display backplane substrate;
