Abstract

A bezel structure for a display device includes a first resin layer capable of being cured by ultraviolet radiation, an ink layer including a non-volatile solvent disposed on the first resin layer, a second resin layer disposed in the ink layer, and an upper structure disposed on the ink layer. The second resin layer prevents an uncured portion of the first resin layer from permeating into a cavity in the ink layer.

First claim

What is claimed is:

1. A bezel structure for a display device, the bezel structure comprising:
a first resin layer, the first resin layer being curable by ultraviolet radiation;
a first ink layer on the first resin layer, the first ink layer including a non-volatile solvent;
a second resin layer on the first ink layer,
a second ink layer on the second resin layer, the second ink layer including a non-volatile solvent and the second resin layer preventing an uncured portion of the first resin layer from permeating into a cavity in the second ink layer; and
an upper structure on the second ink layer.

2. The structure as claimed in claim 1 , wherein the second resin layer includes a transparent polymer resin.

3. The structure as claimed in claim 1 , wherein the upper structure includes a polyethylene-terephthalate (PET) film and a protection window on the PET film.

4. The structure as claimed in claim 3 , wherein the upper structure further includes a pattern layer on the PET film, the pattern layer including a pattern that is patterned by an ultraviolet molding process with a polymer resin.

5. The structure as claimed in claim 4 , wherein the upper structure further includes an oxide layer on the pattern layer, the oxide layer including a plurality of oxides that have respective refractive indexes.

6. The structure as claimed in claim 3 , wherein the PET film and the protection window are bonded by an optically clear adhesive.

7. The structure as claimed in claim 3 , wherein the protection window includes a glass window.

8. A bezel structure for a display device, the bezel structure comprising:
a first resin layer curable by ultraviolet radiation;
an ink layer over the first resin layer, the ink layer including a non-volatile solvent;
a second resin layer between the first resin layer and the ink layer, the second resin layer preventing an uncured portion of the first resin layer from permeating into a cavity in the ink layer; and
an upper structure on the ink layer, the upper structure being on an opposite side of the ink layer from the first resin layer and the second resin layer.

9. The structure as claimed in claim 8 , wherein the second resin layer includes a transparent polymer resin.

10. The structure as claimed in claim 8 , wherein the upper structure includes a polyethylene-terephthalate (PET) film and a protection window on the PET film.

11. The structure as claimed in claim 10 , wherein the upper structure further includes a pattern layer on the PET film, the pattern layer including a pattern that is patterned by an ultraviolet molding process with a polymer resin.

12. The structure as claimed in claim 11 , wherein the upper structure further includes an oxide layer on the pattern layer, the oxide layer including a plurality of oxides that have respective refractive indexes.

13. The structure as claimed in claim 10 , wherein the PET film and the protection window are bonded by an optically clear adhesive.

14. The structure as claimed in claim 10 , wherein the protection window includes a glass window.

15. A display device, comprising:
a display panel;
a functional panel on the display panel;
a flexible printed circuit board (FPCB) in electrical communication with the display panel and the functional panel; and
a bezel structure, the bezel structure being the bezel structure as claimed in claim 1 .

16. The device as claimed in claim 15 , wherein the functional panel includes at least one of a protection film, a polarizing plate, and a touch screen panel.

17. The device as claimed in claim 15 , wherein the second layer is a transparent layer.

18. The device as claimed in claim 17 , wherein the second resin layer includes a transparent polymer resin, and
wherein the upper structure includes a polyethylene-terephthalate (PET) film and a protection window on the PET film.

19. The display device as claimed in claim 15 , wherein:
the display device includes a display area,
the first ink layer, the second resin layer, and the second ink layer of the bezel structure bound the display area, and
the first resin layer and the upper structure of the bezel structure extend into the display area.
