ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application entitled SYSTEM FOR EXCHANGING LAMPS OF LCD earlier filed in the Korean Industrial Property Office on Nov. 2, 1999, and there duly assigned SerialNo. 48167/1999, a copy of which is annexed hereto.
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a system for exchanging a lamp of a liquid crystal display (LCD) apparatus, and in particular to a system for exchanging a lamp of a liquid crystal display apparatus which is capable of easily exchanging a lamp by improving the constructions of a liquid crystal display panel and a panel bracket.
2. Related Art
Generally, a liquid crystal display (LCD) monitor is directed to a display apparatus which is capable of displaying a certain character or symbol based on an optical characteristic by changing a molecular arrangement by applying a voltage to the liquid crystal display.
Since a size of a liquid crystal display monitor may be small, the liquid crystal display monitor can be adapted to a major electronic appliance such as a portable television, a portable computer, a video camera, and the like. A liquid crystal display monitor can be classified into an active type display and a passive type display based on whether a back light unit which generates light is installed or not. The active type display emits light without using the back light unit for thereby displaying a certain character or symbol. As the active type display unit, there are known a cathode ray tube, a light emitting device (LED), and others.
I have found that components of a liquid crystal display related to a lamp could be improved. Efforts have been made to improve and facilitate methods such as lamp insertion, lamp exchange, and lamp connection.
Exemplars of recent efforts in the art include the following five Japan patent publications: Hei 11-52368, Hei 6-273765, Hei 8-43816, Hei 9-5744, and Hei 8-211389.
While these recent efforts provide advantages, I note that they fail to adequately provide an improved efficient and convenient system for exchanging a lamp of a liquid crystal display.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a system for exchanging a lamp of a liquid crystal display which is capable of easily exchanging a lamp of a liquid crystal display.
It is a further object of the present invention to provide an improved system for exchanging a lamp of a liquid crystal display which enables a user to conveniently and efficiently exchange a lamp of a liquid crystal display.
To achieve the above objects and others, there is provided a system for exchanging a lamp of a liquid crystal display which includes a printed circuit board (PCB), a liquid crystal display panel electrically connected with the printed circuit board for thereby displaying a certain character or symbol and having at least one rectangular hole inwardly formed at a lateral surface of the same, a lamp detachably engaged to the rectangular hole of the liquid crystal display panel for emitting light on a screen of the liquid crystal display panel, a panel bracket for integrally fixing the liquid crystal display panel and the printed circuit board, and a cover tiltably engaged at a rim portion of the panel bracket and tilted in the forward and backward directions by a tilting member for thereby opening and closing the rectangular hole of the liquid crystal display panel when the liquid crystal display panel is integrally engaged to the panel bracket, whereby it is possible to easily exchange the lamp by tilting the cover in the forward and backward directions.
The panel bracket includes an opening at an intermediate portion of the same and is formed in a plate shape having rim portions, and a groove having a certain depth is formed in the upper rim portion, so that the cover is engaged to the groove.
The cover is formed in a L-shape, and the lower portion of the vertical portion of the same is tiltably hinged at the groove of the panel bracket by the tilting member, and the horizontal portion of the same opens and closes the upper surface of the liquid crystal display panel.
The tilting member includes an upper plate and a lower plate which are hinged, and the upper plate is engaged to the lower portion of the vertical portion, and the lower plate is engaged to the upper portion of the upper rim portion of the panel bracket.
An elastic plate having a certain elastic force is attached at a lateral portion of the head portion of the lamp, and when the lamp is inserted into the rectangular hole of the liquid crystal display panel, the elastic plate is pressed by an inner surface of the rectangular hole, so that the lamp is fixed to the liquid crystal display panel. The elastic plate is made of a rubber.
A slanted surface is formed on an inner surface of the rectangular hole, so that the head portion of the lamp is easily detachable from the rectangular hole.
To achieve these and other objects in accordance with the principles of the present invention, as embodied and broadly described, the present invention provides an apparatus, comprising: a printed circuit board; a liquid crystal display panel being electrically connected with said printed circuit board, displaying at least one symbol selected from among a plurality of symbols, having a side surface forming a hole; a lamp being removably inserted into the hole and detachably engaging a surface surrounding the hole, said lamp emitting light; a bracket being secured to said panel and said printed circuit board, said bracket having a top edge; and a cover being rotatably mounted to said bracket at said top edge of said bracket, being rotated in a forward direction away from the hole to a first position not covering the hole, being rotated in a backward direction toward the hole to a second position covering the hole, said cover being adjacent to the hole formed by said panel; said lamp being removed from the hole and inserted into the hole when said cover is rotated to said first position not covering the hole.
To achieve these and other objects in accordance with the principles of the present invention, as embodied and broadly described, the present invention provides an apparatus, comprising: a liquid crystal display panel displaying at least one symbol selected from among a plurality of symbols, having a side surface forming a hole; a lamp being removably inserted into the hole and detachably engaging a surface surrounding the hole, said lamp emitting light; a bracket being secured to said panel, said bracket having a top edge; and a cover being rotatably mounted to said bracket at said top edge of said bracket, being rotated in a forward direction away from the hole to a first position not covering the hole, being rotated in a backward direction toward the hole to a second position covering the hole, said cover being adjacent to the hole formed by said panel; said lamp being removed from the hole and inserted into the hole when said cover is rotated to said first position not covering the hole.
