Abstract

A display module configured to improve transmission and reception performance of an electronic device includes: a first panel; a second panel disposed to be opposite to the first panel; and an antenna layer disposed between the first panel and the second panel, and comprising a resin layer formed by an imprinting method, wherein the resin layer includes: an engraved pattern formed in one surface; and an ink layer formed with a conductive material filled in the engraved pattern.

First claim

What is claimed is:

1. A display module comprising:
a window cover;
a touch panel disposed on the window cover;
an antenna layer imprinted on one surface of the touch panel, such that the antenna layer is disposed between the window cover and the touch panel; and
a display panel disposed on another surface of the touch panel;
wherein the antenna layer comprises a resin layer imprinted on the one surface of the touch panel, and the resin layer includes:
at least one groove imprinted in the resin layer, and
a conductive ink in the at least one groove, so that the resin layer having the at least one groove with the conductive ink therein, is disposed between the window cover and the touch panel.

2. The display module according to claim 1 , wherein the at least one groove forms a mesh pattern.

3. The display module according to claim 1 , wherein the antenna layer is transparent.

4. The display module according to claim 1 , wherein the resin layer is formed by applying a resin on a touch panel, pressing the applied resin to form the at least one groove, and applying the conductive ink in the at least one groove.

5. The display module according to claim 1 , wherein
the conductive ink contains conductive particles, and
a substantial portion of the conductive particles have at least one of different sizes and different shapes.

6. The display module according to claim 5 , wherein the conductive ink further contains blackened particles.

7. The display module according to claim 5 , wherein the blackened particles have a lower specific gravity than the conductive particles.

8. A display module comprising:
a window cover;
a window protection layer disposed on one surface of the window cover;
an antenna layer imprinted on one surface of the window cover such that the antenna layer is disposed between the window cover and the window protection layer; and
a touch panel disposed on another surface of the window cover;
a display panel disposed on the touch panel;
wherein the antenna layer comprises a resin layer imprinted on the one surface of the touch panel, and the resin layer includes:
at least one groove imprinted on a surface of the resin layer, and
a conductive ink in the at least one groove, so that the resin layer having the at least one groove with the conductive ink therein, is disposed between the window cover and the window protection layer.

9. The display module according to claim 8 , wherein the at least one groove forms a mesh pattern.

10. The display module according to claim 8 , wherein the antenna layer is transparent.

11. The display module according to claim 8 , wherein the resin layer is formed by imprinting a resin on the window cover, pressing the applied resin to form the at least one groove, and applying the conductive ink in the at least one groove.

12. The display module according to claim 8 , wherein
the conductive ink contains conductive particles, and
a substantial portion of the conductive particles have at least one of different sizes and different shapes.

13. The display module according to claim 12 , wherein the conductive ink further contains blackened particles.

14. The display module according to claim 12 , wherein the blackened particles have a lower specific gravity than the conductive particles.

15. A display module comprising:
a window cover;
a touch panel disposed on the window cover;
a display panel disposed on one surface of the touch panel; and
an antenna layer imprinted on the one surface of the touch panel such that the antenna layer is disposed between the touch panel and the display panel;
wherein the antenna layer comprises a resin layer imprinted on the one surface of the touch panel, and the resin layer includes:
at least one groove imprinted in the resin layer, and
a conductive ink in the at least one groove, so that the resin layer having the at least one groove with the conductive ink therein, is disposed between the display panel and the touch panel.

16. The display module according to claim 15 , wherein the at least one groove forms a mesh pattern.

17. The display module according to claim 15 , wherein the antenna layer is transparent.

18. The display module according to claim 15 , wherein the resin layer is formed by applying a resin on the touch panel, pressing the applied resin to form the at least one groove, and applying the conductive ink in the at least one groove.

19. The display module according to claim 15 , wherein
the conductive ink contains conductive particles, and
a substantial portion of the conductive particles have at least one of different sizes and different shapes.
