Abstract
A display includes a backplane, an array of light sources coupled to the backplane, and a cover plate arranged over the array of light sources. The cover plate includes a first side facing the array of light sources and a second side opposite to the first side. The cover plate includes a microstructure layer and an absorption layer. The microstructure layer is arranged on the first side of the cover plate. The absorption layer is arranged on the microstructure layer facing the array of light sources.
Claims25
A display comprising:
- a backplane;
- an array of light sources coupled to the backplane;
- and
- a cover plate arranged over the array of light sources, the cover plate comprising a first side facing the array of light sources and a second side opposite to the first side,
- wherein the cover plate comprises:
- a microstructure layer arranged on the first side of the cover plate;
- and
- an absorption layer arranged on the microstructure layer facing the array of light sources.
-14. (canceled)
A light emitting diode (LED) display comprising:
- a backplane;
- an array of LEDs coupled to the backplane;
- an array of focusing microstructures attached to the array of LEDs and aligned with the array of LEDs;
- and
- a cover plate attached to the array of focusing microstructures.
-22. (canceled)
A display comprising:
- a substrate;
- an array of light sources arranged on the substrate;
- a first microstructure layer arranged on the substrate and surrounding the light sources of the array of light sources;
- and
- a first absorption layer arranged on the first microstructure layer.
-29. (canceled)
The display of claim 29, wherein the cover plate comprises:
- a second microstructure layer facing the array of light sources;
- a second absorption layer arranged on the second microstructure layer facing the array of light sources;
- and
- an array of openings aligned with the array of light sources extending through the second microstructure layer and the second absorption layer.
The display of claim 29, further comprising:
- an array of focusing microstructures between the array of light sources and the cover plate and aligned with the array of light sources.
A method for fabricating a display, the method comprising:
- forming an array of focusing microstructures on a transfer carrier;
- transferring selected light sources from a light source wafer to permanently bond a first surface of each focusing microstructure of the array of focusing microstructures to the selected light sources;
- removing the transfer carrier from the array of focusing microstructures;
- and
- permanently bonding a second surface of each focusing microstructure of the array of focusing microstructures to a cover plate, wherein the second surface is opposite to the first surface.
(canceled)
A transfer carrier comprising:
- a substrate;
- a temporary adhesive layer attached to the substrate;
- and
- an array of focusing microstructures each comprising a first surface attached to the temporary adhesive layer.
