Abstract
A light emitting diode display panel may comprise a substrate, a plurality of light emitting diodes located over the substrate, and an optical assembly located over the plurality of light emitting diodes. The optical assembly may include a lens array and a diffuser. An inner surface of the lens array may define a plurality of inner curves.
Claims19
A method of making of light emitting diode display panel, comprising:
- locating a plurality of light emitting diodes over a substrate;
- forming an optical assembly including a lens array and a diffuser, wherein the lens array defines at least one of a plurality of inner curves or a plurality of outer curves, wherein forming the optical assembly comprises:
- forming a first region of the diffuser comprising a least one of a first surface pattern, a first material, a first thickness, or a first surface coating, and forming a second region of the diffuser comprising at least one of a second surface pattern, a second material, a second thickness, or a second surface coating, the first surface pattern being different from the second surface pattern, the second material being different from the first material, the second thickness being different from the first thickness, the second surface coating being different from the first surface coating, wherein the first region of the diffuser is located over the first light emitting diode of the plurality of light emitting diodes, and wherein the second region of the diffuser is located over the second light emitting diode of the plurality of light emitting diodes;
- and
- coupling the optical assembly over the plurality of light emitting diodes.
