Abstract

A display device is discussed. A back light unit support structure such as a light source housing for supporting a part of a back light unit and the structure of a back cover are optimized, so that a display panel circuit unit is disposed on the lower front surface of the display device operated in a non-folding COF scheme. Accordingly, a flat plate type back cover may be used and a wall mounting through-hole is provided in an upper edge support member, thereby the display device may be simply installed to the wall in close contact with a wall.

First claim

What is claimed is:

1 . A display device comprising:
a display panel; a back light unit to provide light to the display panel; a display panel driving circuit to drive the display panel; a back light unit support member disposed on a lower side of the display panel, and having a driving circuit receiving part disposed on a front surface of the back light unit support member to receive the display panel driving circuit; an edge support member disposed on an upper side of the display panel and having a wall mounting through-hole formed therein; and a flat plate back cover disposed to cover a rear surface of the back light unit.

2 . The display device of claim 1 , wherein the back light unit support member is a light source housing, and a display panel driving circuit, which is a Source-Printed Circuit Board (S-PCB), is connected to the display panel by a Chip-On-Film (COF).

3 . The display device of claim 2 , further comprising a case top which covers a side surface of the back light unit support member and is bent and extends to one side of an edge on a front surface of the display panel.

4 . The display device of claim 3 , further comprising a heat dissipation member disposed between an inner side surface of the case top and the COF, wherein a Drive-IC (D-IC) is disposed at one side of the COF, and the heat dissipation member is disposed between the inner side surface of the case top and a portion of the COF on which the D-IC is disposed.

5 . The display device of claim 1 , wherein the edge support member is a mounting cabinet or a middle cover assembly to support an upper edge of the display device.

6 . The display device of claim 1 , further comprising a connector including signal terminals and power terminals.

7 . The display device of claim 6 , wherein the connector includes 92 pins or more of the signal terminals and 16 pins or more of the power terminals.

8 . The display device of claim 1 , wherein the driving circuit receiving part includes a stepped part disposed on a front center of the back light unit support member in a rectangular shape.

9 . A display device comprising:
a display panel; a back light unit to provide light to the display panel; a display panel driving circuit to drive the display panel; a back light unit support member disposed on a lower side of the display panel, and having a driving circuit receiving part disposed on a front surface of the back light unit support member to receive; an edge support member disposed on an upper side of the display panel and having a wall mounting through hole formed therein; a flat plate back cover disposed to cover a rear surface of the back light unit; a display panel driving circuit (S-PCB) received in the driving circuit receiving part; a connector including a plurality signal terminals and a plurality of power terminals; and a system board and a power board connected through the connector and a cable.

10 . A display device comprising:
a display panel; a back light unit to provide light to the display panel; a flat plate back cover disposed to cover a rear surface of the back light unit, so that the back light unit is interposed between the display panel and the flat plate back cover; a case top having a first portion extending parallel to the flat plate back cover, and a second portion extending perpendicular to the flat plate back cover; a display panel driving circuit to drive the display panel; a back light unit support member disposed between the first portion of the case top and the flat plate back cover, the backlight unit support member having a driving circuit receiving part disposed on a front surface of the back light unit support member to receive the display panel driving circuit, and having a extending portion that is coplanar with the flat plate back cover; and an edge support member disposed on an upper side of the display panel and having a wall mounting through-hole formed therein.

11 . The display device of claim 10 , wherein the extending portion of the back light unit support member separates the second portion of the case top from an end of the flat plate back cover.

12 . The display device of claim 10 , wherein the extending portion of the back light unit support member is further coplanar with the second portion of the case top.

13 . The display device of claim 10 , wherein the through-hole of the edge support member is formed parallel to the flat plate back cover.

14 . The display device of claim 10 , wherein the edge support member, the extending portion of the back light unit support member and the flat plate back cover are coplanar.

15 . The display device of claim 10 , wherein the flat plate back cover is directly attached to the edge support member and the back light unit support member.
