ABSTRACT:
The present invention claims the benefit of Korean Patent Application No. P2001-32612 filed in Korea on Jun. 11, 2001, which is hereby incorporated by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a flat display case assembly, and more particularly, to a flat display case assembly, in which a flat display module and a frame for holding the module are fastened by a case assembly of a front case and a rear case.
2. Discussion of the Related Art
In general, a flat display is provided with a flat display module and a case for holding the module. The flat display includes components such as an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel) and an FED (Field Emission Display).
Referring to
FIG. 1
, an LCD is provided with a flat display module
1
having a light emitting part
1
a
, and a display part (or a liquid crystal panel part)
1
b
. A frame
2
is provided for holding the edges of the flat display module
1
and maintaining a required gap. A case
3
, having a front case
3
a
and a rear case
3
b
, is provided for holding the display module and the frame together, wherein a picture is reproduced utilizing a molecular motion of the liquid crystal (not shown) in the liquid crystal panel part
1
b.
A related art case assembly of the flat display will be explained, with reference to FIG.
2
.
The related art case assembly is provided with a burring part
13
a
on the front case
3
a
and a screw hole
13
b
in the rear case
3
b
corresponding to the burring part
13
a
. A through hole
2
a
in the frame
2
extends from the front case
3
a
to the rear case
3
b
and corresponds to the screw hole
13
b
. The front case
3
a
, the rear case
3
b
, and the frame
2
are fastened together by inserting and tightening a bolt
4
through the screw hole
13
b
, the through hole
2
a
, and the burring part
13
a
. The burring part
13
a
, which is formed when a part of the front case
3
a
is dented by the bolt
4
, protrudes from the front case
3
a
and has a cylindrical shape. The burring part is also threaded as a result of the pressure of the bolt
4
.
However, the related art flat display case assembly has the following problems.
First, the protrusion of the burring part
13
a
is limited by the thickness of the front case
3
a
. Accordingly, if the front case
3
a
is too thin, the burring part
13
a
will not protrude sufficiently to form a thread with which the bolt
4
can engage.
Furthermore, if the burring part
13
a
is too thin, then it may be susceptible to an external shock or vibration which causes the bolt
4
to disengage from the burring part
13
a
or wears down the thread of the burring part
13
a
, thereby providing insufficient fastening strength between the bolt
4
and the burring part
13
a.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a flat display case assembly that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a flat display case assembly of a front case and a rear case which accurately fastens a flat display module to a case.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a case assembly is provided in a flat display, including a flat display module for presenting a picture; a frame for holding edges of the flat display module; a front case and a rear case for holding the flat display module and the frame in place and fastening the flat display module and the frame together; a first fastening member provided on the front case; and a second fastening member provided on the rear case, wherein the first fastening member and the second fastening member are coupled together to fasten the front case and the rear case.
In another aspect, a case assembly is provided in a flat display, including a flat display module for presenting a picture; a frame for holding edges of the flat display module; a front case and a rear case for holding the flat display module and the frame in place and fastening the flat display module and the frame together; a bolt inserted in a fastening hole in the front case; a nut fixed to an inside surface of the rear case and corresponding to the fastening hole; and a through hole for inserting the bolt therethrough, and a recess for inserting the nut formed in the frame, thereby coupling the bolt and the nut together to fasten the front case and the rear case.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
