Abstract

The liquid crystal display (LCD) apparatus capable of easily exchanging the lamp is disclosed in the present invention. The liquid crystal display apparatus according to the present invention 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.

Claims

1. 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.

2. The apparatus of claim 1, said apparatus corresponding to a liquid crystal display panel apparatus.

3. The apparatus of claim 1, said lamp being removably inserted into the hole formed by said panel corresponding to a plurality of lamps being removably inserted into a respective plurality of holes formed by said panel.

4. The apparatus of claim 1, said bracket integrally securing said panel with said printed circuit board.

5. The apparatus of claim 1, further comprising:

a tilting unit rotatably coupling said cover to said bracket; and

said cover having a front side and a top side, said tilting unit being secured to said front side of said cover and being secured to said top edge of said bracket.

6. The apparatus of claim 5, said tilting unit further comprising:

an upper plate being secured to said front side of said cover; and

a lower plate being secured to said top edge of said bracket, said upper plate being hingedly coupled to said lower plate.

7. The apparatus of claim 1, said lamp further comprising:

an elastic unit having an elastic force, said elastic unit securing said lamp to said panel when said lamp is inserted into the hole.

8. The apparatus of claim 1, said lamp further comprising:

an elastic unit having an elastic force, said elastic unit being pressed by said surface of said panel surrounding the hole when said lamp is inserted into the hole.

9. The apparatus of claim 8, said lamp including a head portion being attached to said elastic unit.

10. 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;
