Abstract

A display module includes a window member, a display panel, and a protective member. The window member includes a front surface, a rear surface facing the front surface in a thickness direction, and a connection surface coupling the front surface to the rear surface. The display panel includes a display part disposed to be spaced apart from the rear surface of the window member and to display an image toward the window member, and an edge part bent from the display part toward the window member. The protective frame accommodates the display panel and is coupled to at least one of the rear surface of the window member and the connection surface.

First claim

What is claimed is:

1. A display module comprising:
a window member comprising a front surface, a rear surface facing away from the front surface in a thickness direction, and a connection surface coupling the front surface to the rear surface;
a display panel comprising a display part spaced apart from the rear surface of the window member and to display an image toward the window member, and an edge part bent from the display part toward the window member;
a protective frame coupled to at least one of the rear surface of the window member and the connection surface to accommodate the display panel; and
a black matrix layer disposed on the rear surface of the window member and overlapping the edge part.

2. The display module of claim 1 , wherein the protective frame comprises:
a bottom portion corresponding to the display part; and
a sidewall portion bent from the bottom and corresponding to the edge part.

3. The display module of claim 2 , wherein the edge part comprises:
a first edge part extending from one end of the display part; and
a second edge part extending from an other end of the display part, which faces the one end in a first direction, and the sidewall portion comprises:
a first sidewall portion corresponding to the first edge part; and
a second sidewall portion corresponding to the second edge part.

4. The display module of claim 3 , wherein the sidewall portion further comprises first and second dummy sidewall portions to connect the first and second sidewall portions, and the first and second dummy sidewall portions face each other in a second direction substantially perpendicular to the first direction.

5. The display module of claim 3 , wherein the first and second sidewall portions are coupled to the rear surface of the window member.

6. The display module of claim 3 , wherein the connection surface comprises a plurality of side surfaces, the first sidewall portion is coupled to a first side surface of the side surfaces, and the second sidewall portion is coupled to a second side surface of the side surfaces, the second side surface facing away from the first side surface in the first direction.

7. The display module of claim 6 , wherein the first and second edge parts are coupled to the rear surface of the window member.

8. The display module of claim 3 , wherein the connection surface comprises a plurality of side surfaces and a plurality of step difference surfaces, the window member comprises a first step difference portion to connect the rear surface of the window member and a first side surface of the side surfaces, and a second step difference portion to connect the rear surface of the window member and a second side surface of the side surfaces, the second side surface facing away from the first side surface in the first direction, and the step difference surfaces define the first and second step difference portions.

9. The display module of claim 8 , wherein the first sidewall portion is coupled to the first step difference portion, and the second sidewall portion is coupled to the second step difference portion.

10. The display module of claim 1 , wherein the black matrix layer has an opening formed therethrough to correspond to the display part.

11. The display module of claim 1 , wherein the display panel comprises:
a base substrate on the protective frame;
a plurality of organic light emitting diodes on the base substrate; and
a sealing layer disposed on the base substrate to cover the organic light emitting diodes.

12. The display module of claim 1 , further comprising a dummy member between the display panel and the window member.

13. The display module of claim 1 , further comprising a touch screen panel between the display panel and the window member.

14. The display module of claim 1 , wherein the connection surface comprises a plurality of side surfaces and a plurality of step difference surfaces, the window member comprises a first step difference portion to connect the rear surface of the window member and a first side surface of the side surfaces, and a second step difference portion to connect the rear surface of the window member and a second side surface of the side surfaces, the second side surface facing away from the first side surface in a first direction, and the step difference surfaces define the first and second step difference portions.

15. A display module comprising:
a window member comprising a front surface, a rear surface facing away from the front surface in a thickness direction, and a connection surface coupling the front surface to the rear surface;
a display panel comprising a display part spaced apart from the rear surface of the window member and to display an image toward the window member, and an edge part bent from the display part toward the window member;
a protective frame coupled to at least one of the rear surface of the window member and the connection surface to accommodate the display panel, the protective frame comprising:
a bottom portion corresponding to the display part; and
a sidewall portion bent from the bottom and corresponding to the edge part; and

a dummy member between the display panel and the window member,
wherein the edge part comprises:
a first edge part extending from one end of the display part; and
a second edge part extending from an other end of the display part, which faces the one end in a first direction, and

the sidewall portion comprises:
a first sidewall portion corresponding to the first edge part; and
a second sidewall portion corresponding to the second edge part.

16. The display module of claim 15 , further comprising a touch screen panel between the display panel and the dummy member.

17. The display module of claim 16 , wherein the touch screen panel comprises:
a flat surface touch part corresponding to the display part;
a first sidewall touch part corresponding to the first edge part; and
a second sidewall touch part corresponding to the second edge part.

18. The display module of claim 15 , further comprising a touch screen panel between the window member and the dummy member.

19. The display module of claim 15 , further comprising an optical member between the display panel and the window member.

20. A display apparatus comprising:
a display module;
a main circuit member electrically coupled to the display module; and
a housing accommodating the main circuit member and coupled to the display module, the display module comprising:
a window member comprising a front surface, a rear surface facing away from the front surface in a thickness direction, and a connection surface coupling the front surface to the rear surface;
a display panel comprising a display part spaced apart from the rear surface of the window member and to display an image toward the window member, and an edge part bent from the display part toward the window member;
a protective frame coupled to at least one of the rear surface of the window member and the connection surface to accommodate the display panel; and
