Abstract

An electronic device is provided. The electronic device includes a substrate and a plurality of light-emitting assemblies. The substrate includes a first edge, an edge region, and a central region. The edge region is adjacent to the first edge. The central region is adjacent to the edge region and away from the first edge. The light-emitting assemblies are disposed on the substrate, and each of the light-emitting assemblies has a tuning element and a light-emitting element. The light-emitting assemblies further include a first light-emitting assembly and a second light-emitting assembly. The first light-emitting assembly is disposed in the central region and has a first light-emitting pattern. The second light-emitting assembly is disposed in the edge region and has a second light-emitting pattern. At a viewing angle of 60°, the brightness of the first light-emitting pattern is higher than the brightness of the second light-emitting pattern.

Claims (45)

1 . An electronic device, comprising:

a substrate, comprising:

a second light-emitting assembly disposed in the edge region and having a second light-emitting pattern,

wherein at a viewing angle of 60°, a brightness of the first light-emitting pattern is higher than a brightness of the second light-emitting pattern; and

a diffuser over the substrate, wherein the diffuser covers the light-emitting assemblies and abuts against the first edge of the substrate.

2 . The electronic device as claimed in claim 1 , wherein the tuning element surrounds the light-emitting element, the tuning element of the first light-emitting assembly has a first height, the tuning element of the second light-emitting assembly has a second height, and the first height is less than the second height.

3 . The electronic device as claimed in claim 2 , wherein the tuning element comprises a reflective material.

4 . The electronic device as claimed in claim 2 , wherein the tuning element comprises a spacer between the light-emitting elements.

5 . The electronic device as claimed in claim 4 , wherein the spacer is lower than a top surface of the light-emitting element of the first light-emitting assembly.

6 . The electronic device as claimed in claim 4 , wherein the spacer is higher than a top surface of the light-emitting element of the second light-emitting assembly.
