Abstract

In a display apparatus and a method for assembling the display apparatus, the display apparatus includes for an embodiment a backlight assembly, a lower receiving member, a display panel and an upper receiving member. The backlight assembly provides light. The lower receiving member receives the backlight assembly. The display panel is disposed over the backlight assembly. An end portion of the upper receiving member is disposed on a non-display area of the first substrate and protrudes between an end portion of the front case and the first substrate. The upper receiving member is combined with the lower receiving member and fixes the display panel. Thus, the display panel may be safely fixed (secured).

Claims

1. A display apparatus including a display panel having a first substrate and a second substrate disposed under the first substrate, and a front case covering the display panel, end portions of the first and second substrates being arranged offset with respect to each other, the display apparatus comprising:

a backlight assembly providing light;

a lower receiving member receiving the backlight assembly,

wherein the display panel is disposed over the backlight assembly; and

an upper receiving member combined with the lower receiving member and fixing the display panel, an end portion of the upper receiving member being disposed on a non-display area of the first substrate and protruding between an end portion of the front case and the first substrate,

wherein the display panel includes a display area and a non-display area, and the end portion of the upper receiving member has a substantially same color as the non-display area.

2. The display apparatus of claim 1, further comprising a mold frame disposed between the lower receiving member and the upper receiving member, to support the display panel.

3. The display apparatus of claim 2, wherein the mold frame comprises a first protrusion supporting the first substrate and a second protrusion supporting the second substrate.

4. The display apparatus of claim 1, wherein the end portion of the upper receiving member protrudes so that a distance from a display area of the first substrate to the end portion of the front case is longer than the distance from the display area of the first substrate to the end portion of the upper receiving member.

5. The display apparatus of claim 4, wherein a black matrix is formed in the non-display area of the first substrate, and the end portion of the upper receiving member overlaps with the black matrix.

6. The display apparatus of claim 5, wherein the end portion of the front case has a downward L shape, so that an end surface of the front case faces an upper surface of the end portion of the upper receiving member.

7. The display apparatus of claim 6, wherein the end portion of the upper receiving member has an upward L shape, to correspond to the end portion of the front case.

8. The display apparatus of claim 7, wherein the end portion of the upper receiving member has a black surface.

9. The display apparatus of claim 8, wherein a black tape is attached to the end portion of the upper receiving member to form the black surface.

10. The display apparatus of claim 9, wherein powder is coated on the end portion of the upper receiving member to form the black surface.

11. The display apparatus of claim 1, further comprising a polarizing plate disposed on the first substrate.

12. The display apparatus of claim 11, wherein the end portion of the upper receiving member is disposed on the polarizing plate, to fix the polarizing plate and the display panel.

13. The display apparatus of claim 12, wherein the end portion of the second substrate, the end portion of the first substrate, an end portion of the polarizing plate and the end portion of the upper receiving member overlap with each other in a line.

14. The display apparatus of claim 1, wherein the front case comprises a plastic based material, and the upper receiving member comprises a metal.

15. A display apparatus including a unit display panel having a first substrate and a second substrate disposed under the first substrate, and a front case covering a plurality of unit display panels combined with each other, end portions of the first and second substrates being arranged offset with respect to each other, the display apparatus comprising:

a backlight assembly providing light;

a lower receiving member receiving the backlight assembly;

a tiled display panel disposed over the backlight assembly and including the plurality of unit display panels combined with each other; and

an upper receiving member combined with the lower receiving member and fixing the tiled display panel, end portion of the upper receiving member being disposed on a non-display area of the first substrate and protruding between an end portion of the front case and the first substrate,

wherein the tiled display panel includes a display area and a non-display area, and the end portion of the upper receiving member has a substantially same color as the non-display area.

16. The display apparatus of claim 15, wherein the first substrate of the unit display panel is disposed on the second substrate of adjacent unit display panel, to form the tiled display panel.

17. The display apparatus of claim 16, further comprising a mold frame disposed between the lower and upper receiving members and including a first protrusion and a second protrusion, the first protrusion supporting the first substrate of a first outermost unit display panel, the second protrusion supporting the second substrate of a second outermost unit display panel, the first outermost unit display panel being opposite to the second outermost unit display panel.

18. The display apparatus of claim 15, wherein the end portion of the upper receiving member protrudes, so that a distance from a display area of the first outermost unit display panel to the end portion of the front case is longer than the distance from the display area of the first outermost unit display panel to the end portion of the upper receiving member.

19. The display apparatus of claim 18, wherein a black matrix is formed in the non-display area of the first substrate of the first outermost unit display panel, and the end portion of the upper receiving member overlaps with the black matrix.

20. A method for assembling a display apparatus, the display apparatus including a display panel having a first substrate and a second substrate disposed under the first substrate, and a front case covering the display panel, end portions of the first and second substrates being cut offset with respect to each other, the method comprising:

receiving a backlight assembly in a lower receiving member;

disposing the display panel over the backlight assembly;

combining an upper receiving member with the lower receiving member;

disposing an end portion of the upper receiving member on a non-display area of the first substrate, to fix the display panel using the upper receiving member; and

disposing an end portion of the front case over the non-display area of the first substrate, so that the end portion of the upper receiving member protrudes between the end portion of the front case and the first substrate,

wherein the display panel includes a display area and a non-display area, and the end portion of the upper receiving member has a substantially same color as the non-display area.

21. The method of claim 20, further comprising disposing a mold frame having a first protrusion supporting the first substrate and a second protrusion supporting the second protrusion between the lower receiving member and the upper receiving member.
