Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display cabinet such as a television receiver and a display monitor using a liquid crystal panel.

[0002]

2. Description of the Related Art FIGS. 6 and 7 show the structure of a conventional display cabinet, in which 1 is a front cabinet having a window 2, and 3 is a screen attached to the back of the front cabinet 1. Liquid crystal panel, which you can see from 2
Reference numeral 4 is a fluorescent lamp that illuminates the liquid crystal panel 3, 5 is a reflector that efficiently collects the light of the fluorescent lamp 4 into the liquid crystal panel 3, 6 is a diffuser plate that uniformly diffuses the light incident on the liquid crystal panel 3, and 7 is a printed board , 8 are rear cabinets that cover the rear surface of the front cabinet 1.

In the conventional example thus constructed, the liquid crystal panel 3, the fluorescent lamp 4, the reflector 5, the diffuser plate 6 and the printed board 7 are shown in FIG. 7 between the front cabinet 1 and the rear cabinet 8. The liquid crystal panel 3 controls the transmission of light emitted from the fluorescent lamp 4 and displays an image on the front surface of the liquid crystal panel 3.

[0004]

By the way, the conventional design of a cabinet for a display has been changed by attaching decorations to the front cabinet 1 or the rear cabinet 8 by post-processing, printing or painting.
Although the number of parts and the number of processes increase and the manufacturing cost increases, there is a problem that a new design cannot be created.

The present invention has been made to solve such a problem, and an object thereof is to provide a cabinet for a display capable of creating a novel design without increasing the number of parts or the number of steps. is there.

[0006]

According to the present invention, light from a light source is uniformly diffused by a diffusion plate, and all or part of an outer peripheral edge portion of the diffusion plate for irradiating a liquid crystal panel is exposed to the surroundings. The display cabinet is designed to illuminate the surrounding area.

In addition, the inner end surface of the brim, which is formed by bending all or part of the outer peripheral edge of the diffuser plate into a hook shape, has two surfaces facing each other covered with a reflective film. By arranging the outer end faces of the light guide plate, which emits the light incident from the outer end faces, so as to face each other, the light is emitted brighter.

[0008]

According to the present invention, it is possible to create a novel design in which the outer periphery of the cabinet is illuminated and the viewer's eyes are attracted without increasing the number of parts and the number of steps.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show the structure of an embodiment of the present invention. In FIGS. 1 to 3, the same reference numerals as those in FIG. 6 denote the same parts, and 9 denotes a main body. 9a is a diffusing plate in which a flange 9b is formed by bending the entire outer peripheral edge portion into a hook shape.

In the present embodiment thus constructed,
The liquid crystal panel 3 is housed between the front cabinet 1 and the diffuser plate 9, and the fluorescent lamp 4, the reflector 5 and the printed board 7 are housed between the diffuser plate 9 and the rear cabinet 8 respectively, and the diffuser plate is also housed. The collar 9b of 9 is sandwiched between the front cabinet 1 and the rear cabinet 8 so that the outer end surface of the collar 9b is exposed from between the front cabinet 1 and the rear cabinet 8. Therefore, most of the light emitted from the fluorescent lamp 4 is uniformly diffused in the main body 9a of the diffusion plate 9 and radiated to the liquid crystal panel 3, but a part of the light incident on the diffusion plate 9 is emitted from the main body 9a. It is guided to the collar 9b and radiated to the outside from the outer end surface of the collar 9b. That is, when the fluorescent lamp 4 is turned on,
The joint portion between the front cabinet 1 and the rear cabinet 8 shines, and the eyes of the viewer can be attracted.

4 and 5 show the structure of another embodiment of the present invention. In FIGS. 4 and 5, the same reference numerals as those in FIG. 1 denote the same parts, and 10 is the same. A reflective film is formed by vapor-depositing aluminum on the upper and lower surfaces of the frame of the liquid crystal panel 3 which is open at the portion facing the screen portion in the figure.
It is a light guide plate covered with 11.

In the present embodiment thus constructed,
The liquid crystal panel 3 is housed between the front cabinet 1 and the diffuser plate 9, and the light guide plate 10, the fluorescent lamp 4, the reflector 5 and the printed board 7 are housed between the diffuser plate 9 and the rear cabinet 8, respectively. At the same time, the collar 9b of the diffuser plate 9 is sandwiched between the front cabinet 1 and the rear cabinet 8 to form the collar 9b.
Outer end faces of front cabinet 1 and rear cabinet 8
And the outer end surface of the light guide plate 10 is installed at a position facing the inner end surface of the collar 9b of the diffusion plate 9.

Therefore, most of the light emitted from the fluorescent lamp 4 is uniformly diffused in the main body 9a of the diffusion plate 9 and radiated to the liquid crystal panel 3, but a part of the light incident on the diffusion plate 9 is generated. It is guided to the collar 9b from the main body 9a and is radiated to the outside from the outer end surface of the collar 9b. At the same time, the light incident on the inner end surface of the light guide plate 10 is guided while being repeatedly reflected between the upper and lower reflection films 11 and is emitted from the outer end surface of the light guide plate 10, but this light is on the outer side of the light guide plate 10. The light enters the inner end surface of the collar 9b of the diffusion plate 9 facing the end surface and is radiated to the outside from the outer end surface of the collar 9b. That is, when the fluorescent lamp 4 is turned on, the joint portion between the front cabinet 1 and the rear cabinet 8 shines brighter than in the embodiment shown in FIGS. 1 to 3, and the eyes of the viewer can be more attracted.

In the description of the present invention, the main body 9a of the diffuser plate 9 has been described as an example in which the entire periphery of the outer peripheral edge of the main body 9a is bent into a hook shape to form the collar 9b. The entire circumference of the outer peripheral edge portion may be sandwiched between the front cabinet 1 and the rear cabinet 8 as it is, or the main body 9 of the diffusion plate 9 may be attached.
A flange 9b formed by bending a part of the outer peripheral edge of a or a part of the outer peripheral edge of the main body 9a of the diffusion plate 9 into a hook shape is attached between the front cabinet 1 and the rear cabinet 8. May be.

[0016]

As described above, according to the present invention,
This has the effect of creating a novel design in which the outer periphery of the cabinet is illuminated and the viewer's eyes are drawn, without increasing the number of parts or processes.
