Abstract

A light-emitting assembly is provided. The light-emitting assembly includes a light source, a reflection-reducing component and a reflective component. The reflection-reducing component is disposed adjacent to the light source. The reflective component is disposed adjacent to the reflection-reducing component. The reflection-reducing component includes a first glue layer, a second glue layer and a substrate layer. The substrate layer is disposed between the first glue layer and the second glue layer. In addition, a top surface of the substrate layer that is in contact with the second glue layer has a curved profile.

Claims (26)

1. A light-emitting assembly, comprising:

a light source;

a reflection-reducing component disposed adjacent to the light source; and

a reflective component disposed between the reflection-reducing component and the light source in a top-view,

wherein the reflection-reducing component comprises a first glue layer, a second glue layer and a substrate layer, and the substrate layer is disposed between the first glue layer and the second glue layer, and a top surface of the substrate layer that is in contact with the second glue layer a plurality of protrusions.

2. The light-emitting assembly as claimed in claim 1 , further comprising an optical plate, wherein the optical plate is disposed on the reflection-reducing component and the reflective component.

3. The light-emitting assembly as claimed in claim 2 , further comprising a housing component disposed adjacent to the optical plate and on the reflection-reducing component.

4. The light-emitting assembly as claimed in claim 3 , which has an active region and a border region adjacent to the active region, wherein a portion of the reflective component is disposed in the active region, and another portion of reflective component is disposed in the border region.

5. The light-emitting assembly as claimed in claim 4 , wherein a first width of the reflection-reducing component between the housing component and the reflective component in the border region is greater than or equal to a second width of the reflective component in the border region.

6. The light-emitting assembly as claimed in claim 5 , wherein a ratio of the second width to the first width is in a range from 1:1 to 1:2.

7. The light-emitting assembly as claimed in claim 2 , wherein the light source is disposed adjacent to a side of the optical plate.

8. The light-emitting assembly as claimed in claim 7 , wherein the optical plate is a light guide plate.

9. The light-emitting assembly as claimed in claim 2 , wherein the reflective component is in contact with a plurality of dots and an air gap exists between the optical plate and the reflective component.

10. A light-emitting assembly, comprising:

a light source;

a reflection-reducing component disposed adjacent to the light source; and

a reflective component disposed between the reflection-reducing component and the light source in a top-view,

wherein the reflection-reducing component comprises a first glue layer, a second glue layer and a substrate layer, and the substrate layer is disposed between the first glue layer and the second glue layer, and a top surface of the second glue layer has a plurality of protrusions.

11. The light-emitting assembly as claimed in claim 10 , further comprising an optical plate, wherein the optical plate is disposed on the reflection-reducing component and the reflective component.

12. The light-emitting assembly as claimed in claim 11 , further comprising a housing component disposed adjacent to the optical plate and on the reflection-reducing component.

13. The light-emitting assembly as claimed in claim 12 , which has an active region and a border region adjacent to the active region, wherein a portion of the reflective component is disposed in the active region, and another portion of reflective component is disposed in the border region.

14. The light-emitting assembly as claimed in claim 13 , wherein a first width of the reflection-reducing component between the housing component and the reflective component in the border region is greater than or equal to a second width of the reflective component in the border region.

15. The light-emitting assembly as claimed in claim 14 , wherein a ratio of the second width to the first width is in a range from 1:1 to 1:2.

16. The light-emitting assembly as claimed in claim 11 , wherein the light source is disposed adjacent to a side of the optical plate.

17. The light-emitting assembly as claimed in claim 16 , wherein the optical plate is a light guide plate.

18. The light-emitting assembly as claimed in claim 11 , wherein the reflective component is in contact with a plurality of dots and an air gap exists between the optical plate and the reflective component.
