Abstract

A display apparatus that is easily installed and assembled and a tiled display apparatus including the same are provided. The display apparatus comprises a display panel, and a support member supporting the display panel, and a power transfer member rotatably disposed on a first side of the support member.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display panel; and
a support member supporting the display panel, wherein the support member includes:
a main body supporting the display panel; and
a power transfer member disposed on a first side of the main body, wherein the power transfer member includes:
a rotating portion rotatably coupled to the first side of the main body;
a stepped portion disposed at a first portion of the rotating portion; and
a terminal portion disposed at a second portion of the rotating portion that is opposite to the first portion of the rotating portion.

2. The display apparatus of claim 1 , wherein the stepped portion protrudes from an upper surface of the rotating portion in a thickness direction of the rotating portion, and the stepped portion has an inclined surface on at least one side.

3. The display apparatus of claim 2 , wherein the first side of the main body includes:
an insertion groove into which the power transfer member is inserted;
a bottom surface adjacent to the insertion groove; and
a vertical surface perpendicular to the bottom surface, and
wherein a distance between the bottom surface and a lower surface of the rotating portion corresponding to the stepped portion is equal to, or greater than, a length by which the stepped portion protrudes from the first end of the rotating portion.

4. The display apparatus of claim 1 , wherein the support member includes a support protruding from the first side of the main body, and
the support includes:
a pair of guide members disposed in parallel with a front surface of the display panel; and
a pair of arms connected to the pair of guide members and disposed in parallel with the first side of the main body in a thickness direction of the main body.

5. The display apparatus of claim 4 , wherein the main body further includes a second side disposed in parallel with the first side of the main body, and
the second side of the main body includes:
a fastening portion inserted into a support groove provided between the pair of guide members; and
a recess with a width smaller than a width of the fastening portion.

6. The display apparatus of claim 4 , wherein the main body further includes a second side disposed in parallel with the first side of the main body,
the support member is a first support member and the support is a first support,
at least a portion of the first support is a conductive material,
at least a portion of the second side of the main body is the conductive material and is configured to be electrically connected to a second support of the conductive material of a second support member of another display apparatus, and
the first support of the conductive material and the power transfer member are configured to transfer voltages different from each other.

7. The display apparatus of claim 1 , wherein the support member further includes a power receiving member having a power receiving terminal connectable to a power source,
the power receiving member is disposed on a second side of the main body, the second side of the main body disposed in parallel with the first side of the main body, and
a width of the power receiving terminal is equal to or wider than a width of the terminal portion of the power transfer member.

8. The display apparatus of claim 1 , wherein the main body further includes:
a second side disposed in parallel with the first side of the main body; and
a third side connected to one side of the first side of the main body and to one side of the second side of the main body,
wherein the third side of the main body includes a protrusion extending in a direction perpendicular to a thickness direction of the main body, and
the protrusion of the third side of the main body has a thickness less than a thickness of the main body.

9. The display apparatus of claim 8 , wherein the main body further includes a fourth side disposed in parallel with the third side of the main body, and the fourth side of the main body includes a recess groove into which the protrusion of the third side of the main body is inserted.

10. The display apparatus of claim 1 , wherein the power transfer member of the support member is one of a plurality of power transfer members including a first power transfer member configured to transfer a positive voltage and a second power transfer member configured to transfer a negative voltage.

11. A display apparatus, comprising:
a display panel;
a support member supporting the display panel; and
a power transfer member rotatably disposed on a first side of the support member,
wherein the support member includes a main body supporting the display panel,
wherein the power transfer member includes:
a rotating portion rotatably coupled to the first side of the main body;
a stepped portion disposed at a first portion of the rotating portion, and
a terminal portion disposed at a second portion of the rotating portion that is opposite to the first portion of the rotating portion.

12. The display apparatus of claim 11 , further comprising:
a power receiving member disposed on a second side of the support member, the second side of the support member disposed in parallel with the first side of the support member,
wherein the power receiving member is disposed at a position corresponding to the power transfer member.

13. The display apparatus of claim 12 , further comprising:
an individual driving circuit disposed inside the support member, the individual driving circuit configured to drive the display panel;
a first connector connecting the individual driving circuit with the power receiving member; and
a second connector connecting the power receiving member with the power transfer member.

14. The display apparatus of claim 11 , wherein the display panel includes:
a substrate; and
a display portion having a plurality of pixels disposed on the substrate, and
a size of the display portion is the same as that of the substrate.

15. The display apparatus of claim 14 , wherein each of the plurality of pixels is arranged on the substrate at a first interval,
the first interval is a distance between centers of two adjacent pixels, and
a second interval between a center of outermost pixels of the plurality of pixels and an outer side of the substrate is less than, or equal to, a half of the first interval.

16. A tiled display apparatus, comprising:
a stand frame; and
a plurality of display apparatuses connected to the stand frame in a tiled arrangement,
wherein each of the plurality of display apparatuses includes:
a display panel;
a support member supporting the display panel; and
a power transfer member rotatably disposed on a first side of the support member,
wherein the support member includes a main body supporting the display panel,
wherein the power transfer member includes:
a rotating portion rotatably coupled to the first side of the main body;
