Abstract

A display device includes a substrate, a light-emitting member, and an anti-reflective glass layer. The light-emitting member is on the substrate. The anti-reflective glass layer is over the light-emitting member, and the anti-reflective glass layer has a transmittance of 40-95%. The anti-reflective glass layer includes a glass layer and a light-absorbing layer. The glass layer has a rough top surface and a haze of 70-80%. The light-absorbing layer is on the rough top surface of glass layer.

Claims (24)

1. A display device, comprising:

a substrate;

a light-emitting member on the substrate; and

an anti-reflective glass layer over the light-emitting member, wherein the anti-reflective glass layer has a transmittance of 40-95% and comprises:

a glass layer having a rough top surface and a haze of 70-80%;

a light-absorbing layer on the rough top surface of the glass layer; and

a gray encapsulant layer between the light-emitting member and the glass layer, and surrounding the light-emitting member, wherein the gray encapsulant layer comprises an encapsulating material and a plurality of second light-absorbing particles dispersed in the encapsulating material, and the second light-absorbing particles is present in the encapsulating material at a weight percentage of about 0.1-0.5%.

2. The display device of claim 1 , wherein the light-emitting member comprises a red LED chip, a green LED chip, and a blue LED chip.

3. The display device of claim 1 , wherein a top of the light-emitting member is spaced apart from a bottom of the glass layer by a gap ranged from 100 μm to 150 μm.

4. The display device of claim 1 , wherein the light-absorbing layer comprises a polymer and a plurality of first light-absorbing particles dispersed in the polymer.

5. The display device of claim 1 , further comprising a circular polarizer layer between the light-emitting member and the glass layer.

6. The display device of claim 1 , further comprising a transparent encapsulant layer between the light-emitting member and the glass layer, and surrounding the light-emitting member.

7. A display device, comprising:

a first substrate and a second substrate neighboring the first substrate, wherein a joint interface is present between the first substrate and the second substrate;

a first light-emitting member and a second light-emitting member respectively disposed on the first substrate and the second substrate; and

an anti-reflective glass layer over the first and the second light-emitting members, wherein the anti-reflective glass layer has a transmittance of 40-95% and comprises:

a glass layer covering the first light-emitting member, the second light-emitting member, and the joint interface, wherein the glass layer has a rough top surface and a haze of 70-80%;

a light-absorbing layer on the rough top surface of the glass layer; and

a gray encapsulant layer between the first and the second light-emitting members and the glass layer, and surrounding the first and the second light-emitting members, wherein the gray encapsulant layer comprises a encapsulating material and a plurality of second light-absorbing particles dispersed in the encapsulating material and the second light-absorbing particles is present in the encapsulating material at a weight percentage or about 0.1-0.5%.

8. The display device of claim 7 , wherein each of the first light-emitting member and the second light-emitting member comprises a red LED chip, a green LED chip, and a blue LED chip.

9. The display device of claim 7 , wherein a top of the first light-emitting member and a top of the second light-emitting member is respectively spaced apart from a bottom of the glass layer by a gap ranged from 100 μm to 150 μm.

10. The display device of claim 7 , wherein the light-absorbing layer comprises a polymer and a plurality of first light-absorbing particles dispersed in the polymer.

11. The display device of claim 7 , further comprising a circular polarizer layer between the first and the second light-emitting members and the glass layer.

12. The display device of claim 7 , further comprising a transparent encapsulant layer between the first and the second light-emitting members and the glass layer, and surrounding the first and the second light-emitting members.
