DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat display device capable of separating a flat display unit such as a plasma display panel and a tuner box as a signal supply unit.

[0002]

2. Description of the Related Art A flat display device has a smaller depth and is lighter than a display device using a CRT (cathode ray tube) having a display portion of the same screen size, so that it is difficult to use a conventional CRT display device. Various usage patterns have been proposed. For example, in a narrow space, it has been proposed to place the device on a table using a stand or to hang it on a wall using a wall-mounted unit.

Here, as an example of a flat display device, a configuration of a plasma display panel device will be described with reference to FIG.

[0004] This plasma display panel (hereinafter, referred to as a plasma display panel)
The main parts of the device (referred to as “PDP”) are divided into a display unit 101 that displays an image according to an image signal, a tuner box 102 that receives and supplies an image signal, and a speaker unit 103 that outputs sound. The display unit 101 and the tuner box 102 are connected by a cable 114. Further, this PDP device is provided with a stand 105 prepared separately.
Alternatively, it is installed on a table or a wall surface by the wall hanging unit 106.

[0005] When used on a wall, it is particularly required that the device to be hung on the wall be small in depth and light in weight. Therefore, only the display unit 101 is installed on the wall surface. The tuner box 102 will be separated and installed at another place. Further, a television configured using a PDP requires an operation unit, which is provided in the tuner box 102 in consideration of operability. In consideration of a place where the tuner box 102 is installed, the cable 114 has a certain length (3 m to 3 m).
10m) is required.

When used as a tabletop, a stand 105 is used instead of the wall-mounted unit 106. Even in this case, the display unit 101 and the tuner box 102 are connected by the cable 114.

[0007]

As described above, the display unit 101 and the tuner box 102 must be connected by the cable 114 even when the desktop display is formed by using the stand 105. However, as described above, cable 1
Since the cable 14 needs a certain length (3 m to 10 m), handling the cable 114 is troublesome. In some cases, the tuner box 102 had to be stored or set aside at another location in accordance with the length of the cable 114.

The height of the stand 105 is set with reference to an ordinary desk. Therefore,
When the PDP device supported by the stand 105 is installed on the floor, the position of the screen is too low to make it difficult to see. Therefore, when it is installed on the floor, it has to be placed on another rack.

Considering the operability, it is preferable to arrange the operation panel section at a different position between the wall-mounted type and the stationary type. Therefore, it is conceivable to separately prepare a model for wall-mounting installation and a model for stationary installation. However, in the case of such a product configuration, a dedicated operation panel unit must be prepared for each model, which causes a problem that the cost is increased.

[0010] It is an object of the present invention to provide a flat display device which can cope with various use modes.

The other components are selectively used according to the usage. Therefore, hereinafter, the description will be made separately for each usage mode of tabletop placement, floor placement, and wall installation.

(1) Table Placement (See FIGS. 1 and 2) In this mode of use, the tuner box 2 and the display unit 1 are integrated using a stand 5 (FIG. 2).

The stand 5 is for mounting the display unit 1 and the tuner box 2 and supporting them. The stand 5 includes a substantially rectangular frame 8 having feet 8a and a base 7 to which the frame 8 is fixed.

On the front and rear sides of the frame 8, screw holes 8b are provided at predetermined positions. On the front side (the side on which the display unit 1 is mounted), hook metal plates 9, 10 for hanging the display unit 1 are screwed using the screw holes 8b. The hook portions 9a and 10a of the hook metal plates 9 and 10 have the same shape as that of the wall-mounting unit 6 (FIG. 6).
Can be engaged. On the other hand, the fixed sheet metal 1
2, the tuner box 2 is screwed and fixed in an upright state (a position in which the longitudinal direction of the tuner box 2 is directed up and down). The tuner box 2 is fixed by screws with the longitudinal direction being the vertical direction and the front end face facing downward. The fixing plate 12 is screwed to the screw hole 2f (see FIG. 3), and can be removed from the tuner box 2 as needed.

The display unit 1 and the tuner box 2 are connected by a cable 17. In this case, the cable 17 may be shorter than the cable 14 because the distance between the tuner box 2 and the display unit 1 is short. Also,
The tuner box 2 is not provided with a front panel 18 (FIG. 6) used for wall-mounted installation.

Left and right lower portions of the frame 8 are provided with legs 8a extending in the front-rear direction and having screw holes (not shown) at various places. On the other hand, the base 7 is provided with a screw hole 7a at a position corresponding to the screw hole of the foot 8a. The frame 8 can maintain a more stable state by fixing the feet 8a to the upper surface of the base 7 with screws.

A front panel 13 is mounted below the display unit 1 between the left and right speaker units 3.
Since the length of the front panel 13 in the left-right direction is matched with the distance between the left and right speaker units 3,
No gap is left between the speaker unit 3 and the front panel 13.

Further, a mounting portion having an engagement hole 13b is provided at the center of the front panel 13, and the operation panel portion 4 is mounted here. The attachment is performed by fitting the engagement claws 4c into the engagement holes 13b. The size and shape of the mounting portion are adjusted to the operation panel portion 4, so that unnecessary gaps and the like do not remain.

The operation panel 4 and the tuner box 2 are connected by a cable 20. Cable 20
Is passed through the opening 13a provided in the front panel 13, so that the cable 20 cannot be seen from outside the apparatus.

The back side portion of the device in this use mode,
That is, the tuner box 2, the frame 8 and the like are
5 covered. The rear housing 15 has a space sufficient to accommodate the frame 8 and the like. The rear housing 15 is mounted so that the opening is closed by the display unit 1 from the back side of the PDP device. When the rear housing 15 is mounted, the frame 8 and the like are covered by the rear housing 15 and cannot be seen from the outside.

At the approximate center of the rear side of the rear housing 15, a rear door 16 that can be opened and closed is provided. This rear door 16
Is usually closed to protect the tuner box 2 from dust. However, when it is necessary to access the tuner box 2 (for example, when connecting a cable), the user opens the rear door 16 to perform the operation.
Since it is not necessary to remove the entire rear housing 15, the workability is excellent.

In this mode of use, the display unit 1, the tuner box 2 and the like are integrated, so that the apparatus can be easily moved. Further, since the tuner box 2 is supported upright, the occupied space on the table is small. Further, since the display unit 1 and the tuner box 2 are located on opposite sides of the stand 5 with the stand 5 therebetween, the stability is high even from the viewpoint of weight balance.

If this PDP device is used at the time of sale (or at the time of shipment), since the connection of cables and the like has already been made, the purchaser can immediately confirm the operation after purchase. it can.

(2) Floor Placement (See FIGS. 4 and 5) In this mode of use, a box type base 19 is used instead of the above-described base 7 (FIG. 2). Other points are the same as those in the case of the desktop installation.

The base 19 is raised to some extent in consideration of installation on the floor. Therefore, the visibility does not deteriorate even when the PDP device is installed on the floor. In addition, the shape is a substantially quadrangular prism shape in consideration of stability. However, the upper portion 19a is extended rearward in accordance with the length of the foot 8a of the frame 8. In addition, the base portion 19b extends in the front, rear, left, and right directions to further enhance stability.

In this mode of use, since the display unit 1 is located at a higher position from the installation surface of the base 19 (that is, the floor), the visibility is excellent even when the display unit 1 is placed on the floor.

The shape and height of the base 19 are not limited to these. Any configuration may be used as long as there is a height and a sufficient stability to obtain the optimum visibility according to the installation position.

(3) Wall-Mounting Installation (See FIG. 6) In this mode of use, the display unit 1 is installed on a wall surface using the slit 11 on the back surface of the display unit 1 and the wall-mounting unit 6. The tuner box 2 is installed separately from the display unit 1. In this use mode, the rear housing 15, the stand 5, and the like are not used.

The wall-mounting unit 6 has a substantially rectangular plate-shaped support plate portion 6a provided with screw holes 6c at various places, and a support plate portion 6a.
and a hook 6b extending upward when the wall hanging unit 6 is fixed to a vertical wall surface.

Installation on a wall is performed as follows. That is, the wall hanging unit 6 is fixed to the wall surface in advance. This fixing is performed by screwing using a screw hole. Then, the slit 11 on the back of the display unit 1 is hung on the hook 6b.

On the other hand, the front panel 18 and the operation panel section 4 are mounted on the front end face of the tuner box 2 (see FIG. 6). In this mounting, the engaging claws (not shown) provided on the rear side of the front panel 18 are fitted into the engaging holes 2d, while the engaging claws 4c (see FIG. 2) of the operation panel portion 4 are fitted into the engaging holes 2e. This is done by fitting. The electrical connection between the tuner box 2 and the operation panel unit 4 is made by a cable 20 as in other usage modes. The cable 20 is housed in the front panel 18 and cannot be seen from the outside. Since the front panel 18 and the like have the same outer shape as the tuner box 2, the tuner box 2, the front panel 18, and the operation panel unit 4 have a strong sense of unity when mounted on the tuner box 2.

The tuner box 2 is installed with the mounted front panel 18 and the like facing the operator. In this case, the tuner box 2 is installed at a desired position distant from the display unit 1 to some extent as described above. The connection with the display unit 1 is made by a cable 14. The cable 14 is previously elongated in consideration of such an installation mode.

In this mode of use, since only the display unit 1 is installed on the wall surface, the withstand load required for the wall hanging unit 6 can be reduced. Similarly, the load applied to the wall surface to be installed is small. Further, since the tuner box 2 can be installed near the viewer, the operability is excellent.

The PDP device according to the above-described embodiment is excellent in visibility and operability in any of various use modes (desktop placement, floor placement, wall mounting).

In the above-described embodiment, the height is changed by replacing the base 7 with the base 19.
In addition, the height can be adjusted by stacking and mounting a desired number of stages.

The “display section” in the claims corresponds to the display section 1 in the above-described embodiment. The “signal supply unit” corresponds to the tuner box 2. “Stand” corresponds to the stand 5. The “support portion” and the “support member” correspond to the frame 8. The “base part” and the “base member” are the base 7 and the base 19
Is equivalent to The “installation surface” corresponds to the tabletop and floor. The “operation panel unit” corresponds to the operation panel unit 4.
The “display device” corresponds to the display unit 1 and the front panel 13. The “mounting unit” corresponds to a lower portion of the display unit 1 (the center of the front panel 13) and a front end surface of the tuner box 2.

[0049]

As described above, according to the present invention, it is possible to provide a flat display device suitable for use in any of a wall-mounted installation, a desktop installation, and a floor installation. Specifically, it is as follows.

The space required for installation on a table or floor can be reduced, and the balance is good and the stability is high.

Further, since the height position can be changed, appropriate visibility can be obtained.
