Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, which is thinly constructed by using a PDP (plasma display panel) or the like for a display body, and can be mounted on a table, suspended from a ceiling, or mounted on a wall. For what makes it easy.

[0002]

2. Description of the Related Art In a display device using a panel-shaped display body such as a PDP, the depth of the display body is thinner than that of a cathode ray picture tube having the same screen size. It has an advantage that the range of choice of the installation method is wider than that of the conventional one using the cathode ray picture tube, such as mounting on a table, hanging from the ceiling, or installing on a wall surface. However, there are many circuit components that generate heat in the circuit mounted on the device, and there is a problem with a method of discharging heat generated internally when the device is downsized and miniaturized. Further, since the selection range of the installation method has widened due to the thinning of the device, it is desirable to be able to cope with various installation methods without changing the frame member as much as possible in order to utilize this feature.

[0003]

In view of the above points, the present invention is apt to release heat generated inside the apparatus, and
It is an object of the present invention to provide a product that can be easily installed on a table, suspended from a ceiling, or installed on a wall.

[0004]

In order to solve the above-mentioned problems, the present invention solves the above-mentioned problems by providing a panel-shaped display body, a frame-shaped frame for mounting the display body on the front side, and the display body mounted on the frame. The display device includes a front panel that covers the front surface and a rear panel that is attached to the back surface of the frame, and at least the frame is made of metal, and heat radiation fins are provided on the outer periphery of the frame.

[0005]

With the above construction, in the display device according to the present invention, the frame is formed into a frame shape by die casting using a metal having good heat conductivity such as aluminum to give rigidity. A display body composed of PDP or the like is attached to the front surface of this frame, and a front panel is attached to the front surface of the display body. By mounting the table mounting tool on the mounting part at the bottom of the frame, it becomes a table mounting type, and by attaching the ceiling suspension to the mounting part on the back of the frame, it becomes a ceiling suspension type.
Alternatively, it can be used as a wall mount type by attaching a wall mount.

It is composed of a main body and a control circuit of the PDP main body attached to the back surface of the PDP main body. The frame 2 is formed in a frame shape by aluminum die casting or the like, and the heat radiation fins 3 are integrally formed on the outer periphery to increase the heat radiation area. A PDP mounting portion and a rear cover mounting portion are provided inside the frame 2, and the fastening members are used to fasten the PDP 1 to the PDP mounting portion and the rear cover 5 to the rear cover mounting portion, respectively. The front panel 4 is mounted so as to be fitted into the edge portion on the front surface side of the frame 2. A screw hole is provided on the bottom surface of the frame 2 so that the table mounting tool can be attached. Further, a screw hole is provided on the back edge of the frame 2, etc., and the ceiling hanging tool or the wall mounting tool can be attached by this screw hole. To do so.

Reference numeral 11 in FIG. 2 is a signal unit, and the other reference numerals are the same as those in FIG. Signal unit 11
Is composed of a processing circuit for a signal supplied to the PDP 1 for displaying an image, a power supply circuit, and the like. As shown in the side view of FIG. 3, the PDP 1 is fastened to the PDP mounting portion 21 provided inside the frame 2 using the fastening member 23, and the rear panel 5 is the rear panel mounting portion 22 provided inside the frame 2.

Reference numeral 33 in (C) is a wall surface fixture, which is attached to the screw hole at the rear edge of the frame 2 by a fastening member so that the apparatus can be installed on the wall surface.

In the above description, an example in which the PDP is used as the display body has been described, but an LCD (liquid crystal display element) may be used.

[0012]

As described above, according to the display device of the present invention, since the frame is formed by die casting using a metal such as aluminum, it has rigidity, and the frame is mounted on the table mount and the ceiling suspension. It is possible to easily support various installation methods by attaching lower tools or wall mounting tools. Further, since the frame has rigidity, the front panel does not need to have rigidity, which provides the advantage that the degree of freedom in design is expanded and various applications can be easily accommodated. Also, since the frame is made of aluminum and has good heat conduction, it is easy to dissipate heat even if a signal unit that generates a relatively large amount of heat is mounted inside the frame, and it is possible to suppress the internal temperature rise. It becomes possible to integrate the device by means of, and it becomes easy to deal with various installation methods as described above.
