Abstract

Disclosed herein is a display apparatus including a liquid crystal panel configured to display an image; a backlight unit including: a light source; and an optical member disposed at a path of light emitted from the light source toward the liquid crystal panel; a chassis disposed on the backlight unit and having a plurality of insertion holes along edges thereof; and a frame configured to support the liquid crystal panel and the optical member, the liquid crystal panel and the optical member provided between the frame and the chassis, wherein the frame is coupled to the plurality of insertion holes of the chassis by fitting.

First claim

What is claimed is:

1 . A display apparatus comprising:
a liquid crystal panel configured to display an image; a backlight unit comprising:
a light source; and
an optical member disposed at a path of light emitted from the light source toward the liquid crystal panel;
a chassis disposed on the backlight unit and having a plurality of insertion holes along edges thereof; and a frame configured to support the liquid crystal panel and the optical member, the liquid crystal panel and the optical member provided between the frame and the chassis, wherein the frame is coupled to the plurality of insertion holes of the chassis by fitting.

2 . The display apparatus according to claim 1 , wherein the frame is formed of a thermoplastic rubber material.

3 . The display apparatus according to claim 1 , wherein the chassis further comprises a bush part protruding backward from edges of the chassis, the bush part forming the plurality of holes.

4 . The display apparatus according to claim 1 , wherein the frame comprises an insertion protrusion part protruding from the frame to be coupled to an insertion hole amongst the plurality of insertion holes of the chassis.

5 . The display apparatus according to claim 4 , wherein the insertion protrusion part comprises an insertion body part, a dimension of the insertion body part being greater than a corresponding dimension of the insertion hole.

6 . The display apparatus according to claim 5 , wherein the insertion protrusion part comprises a guide part having a tapered shape to guide the insertion body part into the insertion hole.

7 . The display apparatus according to claim 1 , wherein the frame comprises a pair of first side frames and a pair of second side frames, a length of the first side frames being greater than a length of the second side frames.

8 . The display apparatus according to claim 7 further comprising a reinforcement member coupled to one of the first side frames and one of the second side frames to support the frame.

9 . The display apparatus according to claim 1 further comprising:
a rear cover coupled to the chassis; and
a circuit board disposed between the chassis and the rear cover and configured to control driving of the display apparatus.

10 . A display apparatus comprising:
a liquid crystal panel configured to display an image; a backlight unit comprising:
a light source; and
an optical member disposed at a path of light emitted from the light source;
a chassis configured to accommodate the backlight unit; a frame having a rectangular shape and supporting the liquid crystal panel and the optical member; and a reinforcement member configured to support at least one portion of the frame supporting the liquid crystal panel and the optical member.

11 . The display apparatus according to claim 10 , wherein the reinforcement member is disposed at a corner portion of the chassis to support the frame.

12 . The display apparatus according to claim 10 , wherein the reinforcement member is coupled to the chassis, the chassis provided between a rear cover and the backlight unit.

13 . The display apparatus according to claim 12 , wherein the chassis comprises a locking hole provided at an edge of the chassis to be coupled to the reinforcement member.

14 . The display apparatus according to claim 13 , wherein the reinforcement member comprises a hook protrusion part protruding toward the rear cover to be coupled to the locking hole of the chassis by a hook connection.

15 . The display apparatus according to claim 10 , wherein the reinforcement member comprises:
a central part; and a plurality of arm parts extending from the central part to be substantially perpendicular to each other.

16 . The display apparatus according to claim 10 , wherein the frame comprises:
first side frames; and second side frames, and wherein the first and the second side frames are coupled to the reinforcement member.

17 . The display apparatus according to claim 16 , wherein the central part of the reinforcement member comprises a connection protrusion to be coupled to one of the first side frames and one of the second side frames.

18 . The display apparatus according to claim 10 , wherein the reinforcement member comprises a liquid crystal panel reinforcement support surface configured to support a side surface of the liquid crystal panel.

19 . The display apparatus according to claim 18 , wherein an interval between the liquid crystal panel reinforcement support surface of the reinforcement member and the side surface of the liquid crystal panel is less than an interval between a liquid crystal panel support surface of the frame and the side surface of the liquid crystal panel.

20 . A display apparatus comprising:
a liquid crystal panel configured to display an image; a backlight unit comprising:
a light source; and
an optical member, the liquid crystal panel provided on a first surface of the backlight unit;
a chassis provided on a second surface opposite to the first surface of the backlight unit and having a plurality of insertion holes along edges thereof; and a frame provided on a backlight unit, the liquid crystal panel and the optical member provided between the frame and the chassis, wherein one of the frame and the chassis comprises a male part and the other of the frame and the chassis comprises a female part, and wherein the frame and the chassis are coupled to each other via the male part and the female part.
