Abstract

A display module is provided. The display module includes a plurality of substrates; a plurality of light-emitting devices mounted on each of the plurality of substrates; a plurality of transparent resins that surrounds the plurality of light-emitting devices; and an opaque molding layer that is disposed on the plurality of substrates between the plurality of transparent resins and covers partial surfaces of the plurality of transparent resins.

Claims (49)

1. A display module comprising:

a plurality of substrates;

a plurality of light-emitting devices mounted on each of the plurality of substrates;

a plurality of transparent resins that surrounds the plurality of light-emitting devices; and

an opaque molding layer that is disposed on the plurality of substrates between the plurality of transparent resins and covers partial surfaces of the plurality of transparent resins,

wherein the opaque molding layer covers a portion of a top surface of one of the plurality of transparent resins.

2. The display module according to claim 1 , wherein the opaque molding layer covers side surfaces of the plurality of transparent resins.

3. The display module according to claim 1 , wherein a height of one of the plurality of light-emitting devices from a surface of a first substrate from among the plurality of substrates is a first height,

wherein a height of one of the plurality of transparent resins from the surface is a second height, and

wherein a height of the opaque molding layer from the surface is greater than or equal to the first height and less than or equal to the second height.

4. The display module according to claim 1 , further comprising a transparent layer that covers the opaque molding layer.

5. The display module according to claim 4 , wherein a portion of the opaque molding layer is interposed between the transparent layer and the one of the plurality of transparent resins along a direction perpendicular to a surface of one of the plurality of substrates.

6. The display module according to claim 1 , wherein the plurality of transparent resins is arranged at regular intervals and surrounds the plurality of light-emitting devices, respectively.

7. The display module according to claim 1 , wherein the plurality of light-emitting devices form a plurality of unit pixels, and

wherein the plurality of transparent resins respectively surround the plurality of unit pixels.

8. A display apparatus comprising:

a plurality of substrates;

a frame configured to support the plurality of substrates;

a plurality of light-emitting devices mounted on each of the plurality of substrates;

a plurality of transparent resins that surround the plurality of light-emitting devices;

an opaque molding layer that is disposed on the plurality of substrates between the plurality of transparent resins and covers partial surfaces of the plurality of transparent resins; and

a transparent layer that covers the opaque molding layer,

wherein the opaque molding layer covers a portion of a top surface of one of the plurality of transparent resins.

9. The display apparatus according to claim 8 , wherein the opaque molding layer surrounds side surfaces of the plurality of transparent resins.

10. The display apparatus according to claim 8 , wherein a height of one of the plurality of light-emitting devices from a surface of a first substrate from among the plurality of substrates is a first height,

wherein a height of one of the plurality of transparent resins from the surface is a second height, and

wherein a height of the opaque molding layer from the surface is greater than or equal to the first height and less than or equal to the second height.

11. The display apparatus according to claim 8 , wherein the plurality of transparent resins is arranged at regular intervals and surrounds the plurality of light-emitting devices, respectively.

12. The display apparatus according to claim 8 , wherein the plurality of transparent resins further comprise a diffusion agent for diffusing light emitted from the plurality of light-emitting devices.

13. The display apparatus according to claim 8 , wherein each of the plurality of transparent resins comprise an area that is exposed by the opaque molding layer, and

wherein the area of each of the plurality of transparent resins comprises a micro protrusion.

14. A method of manufacturing a display apparatus, comprising:

adjacently arranging a plurality of substrates;

mounting a plurality of light-emitting devices on each of the plurality of substrates;

applying a plurality of transparent resins surrounding the plurality of light-emitting devices; and

applying an opaque molding layer on the plurality of substrates between the plurality of transparent resins to cover partial surfaces of the plurality of transparent resins,

wherein the opaque molding layer covers a portion of a top surface of one of the plurality of transparent resins.

15. The method according to claim 14 , wherein the applying the opaque molding layer comprises applying the opaque molding layer such that the opaque molding layer covers side surfaces of the plurality of transparent resins.

16. The method according to claim 14 , wherein a height of one of the plurality of light-emitting devices from a surface of a first substrate from among the plurality of substrates is a first height,

wherein a height of one of the plurality of transparent resins from the surface is a second height, and

wherein the applying the opaque molding layer comprises applying the opaque molding layer such that a height of the opaque molding layer is greater than or equal to the first height and less than or equal to the second height.

17. The method according to claim 14 , wherein the applying the opaque molding layer comprises:

applying an opaque resin on a surface of a transparent layer that corresponds to an entire area of the plurality of substrates; and

attaching the transparent layer on which the opaque resin is applied to the plurality of substrates on which the plurality of transparent resins is disposed.

18. The method according to claim 17 , further comprising removing the transparent layer.

19. The method according to claim 14 , wherein the applying the opaque molding layer comprises:

applying an opaque resin on the plurality of substrates between the plurality of transparent resins to cover partial surfaces of the plurality of transparent resins; and

cutting the opaque resin to planarize a front surface of the opaque molding layer.

20. The method according to claim 14 , wherein the applying the plurality of transparent resins further comprises forming a micro protrusion in a surface of each of the plurality of transparent resins that is exposed by the opaque molding layer.
