Pixel structure

Abstract

A pixel structure includes a substrate, a light-emitting element, a patterned light-absorbing structure, and a light-concentrating structure. The light-emitting element is disposed on the substrate. The patterned light-absorbing structure is disposed on the substrate, wherein the patterned light-absorbing structure includes a reflective layer facing the light-emitting element. The light-emitting element is disposed between the patterned light-absorbing structure and the light-concentrating structure. The vertical projection of the light-emitting element on the substrate falls entirely within the vertical projection of the light-concentrating structure on the substrate, and the vertical projection of the reflective layer on the substrate does not overlap with the vertical projection of the light-concentrating structure on the substrate.

Claims

1. A pixel structure, comprising: substrate; A light-emitting element is disposed on the substrate; A patterned light-absorbing structure is disposed on the substrate, wherein the patterned light-absorbing structure includes a reflective layer facing the light-emitting element; and a light-concentrating structure, wherein the light-emitting element is disposed between the patterned light-absorbing structure and the light-concentrating structure, wherein the vertical projection of the light-emitting element on the substrate falls entirely within the vertical projection of the light-concentrating structure on the substrate, and the vertical projection of the reflective layer on the substrate does not overlap with the vertical projection of the light-concentrating structure on the substrate.

2. The pixel structure as described in claim 1, wherein the patterned light-absorbing structure further includes a first light-absorbing portion, and the reflective layer is disposed on one side of the first light-absorbing portion.

3. The pixel structure as described in claim 2, wherein the reflective layer is adjacent to a top surface of the first light-absorbing portion.

4. The pixel structure as claimed in claim 3, wherein a top surface of the light-emitting element has a first height relative to the substrate, the top surface of the first light-absorbing portion has a second height relative to the substrate, a distance exists between the light-emitting element and the top surface of the first light-absorbing portion, and the ratio of the difference between the first height and the second height to the distance falls within the range of 0.1 to 0.

4.

5. The pixel structure as claimed in claim 2, wherein the included angle between the side and the substrate is in the range of 30 degrees to 50 degrees.

6. The pixel structure as described in claim 2, wherein the first light-absorbing portion completely surrounds the light-emitting element.

7. The pixel structure as claimed in claim 2, wherein the patterned light-absorbing structure further includes a second light-absorbing portion, the second light-absorbing portion being integrally formed with the first light-absorbing portion and having an upper surface parallel to the substrate.

8. The pixel structure as claimed in claim 1, further comprising an anti-reflective layer, wherein the light-emitting element, the patterned light-absorbing structure, and the light-concentrating structure are disposed between the substrate and the anti-reflective layer.

9. The pixel structure as claimed in claim 1, further comprising a filter layer, wherein the light-gathering structure is disposed between the light-emitting element and the filter layer.

10. The pixel structure as claimed in claim 1, further comprising a filter layer, wherein the filter layer is disposed between the light-emitting element and the light-concentrating structure.
