Abstract

PROBLEM TO BE SOLVED: To hold a plasma display panel(PDP) without using any screw, and to easily take out the single PDP body by removing an interposing force by providing a PDP interposing part integrally formed like an E shape, and equipped with a structural body for interposing and holding the PDP. SOLUTION: A PDP 1 is provided with a discharge light emitting part 14 having a pixel electrode 13 on whose periphery a rib 16 is arranged in a space interposed between two glass plates 11 and 12. The discharge light emitting part 14 is formed as a cell structure into which mixed gas is sealed, and when any outer pressure is added, the cells are likely to be destroyed. Thus, it is necessary to hold the PDP in a non-display region where any cell is not present, especially, in a sealed frit part 17 where the two glass plates 11 and 12 are adhered to each other. Thus, the PDP can be interposed without using any screw by a PDP interposing part 21 integrally formed like an E shape, and equipped with a structural body for adjusting an interposing force.

Subsequently, the wedge 3 formed in a D-shape is
The main frame 2 is fitted into a PDP holding force adjusting portion 22 opposite to the PDP holding portion 21, and the flange portion 31 is rotated around a shaft portion 32 having an elliptical cross section as a center of rotation, so that the wedge 3 is attached to the PDP holding force. An operation of increasing the interval between the adjustment units 22 can be provided. On the contrary, as shown in FIG. 4, the PDP holding portion 2 of the main frame 2
The holding force can be variably adjusted by narrowing the interval between the tips of the two.

As described above, according to the first embodiment, the following effects can be obtained. First, the first effect is
That is, the PDP 1 can be held without using screws for fastening. The reason is that the PDP 1 is held only by the force sandwiched by the upper and lower PDP sandwiching portions 21.

A second effect is that the PDP 1 is sandwiched and held by the plasma display panel holder,
By removing the holding force, the PDP 1 can be easily removed. The reason is PDP1
Is sandwiched between the PDP sandwiching portions 21 that form a pair,
At the tip of the U-shaped PDP holding force adjustment unit 22 formed on the opposite side of the base of the holding unit 21 as a boundary, a force that reduces the gap acts, preventing the narrowing at the tip of the PDP holding force adjustment unit 22. This is because the force for holding the PDP 1 is increased by sandwiching the wedge 3 to be held.

A third effect is that when the PDP 1 is separated from the plasma display panel holder, only the components constituting the PDP 1 are used alone, so that separation and disposal are facilitated.

A fourth effect is that the number of components can be reduced. The reason is that a cover member, a mount member, and the like are integrated in place of the conventional plasma display panel holder which is configured by a cover member and a mount member.

(Second Embodiment) FIG. 5 shows a second embodiment of the present invention.
FIG. 3 is a structural cross-sectional view for explaining a plasma display panel holder according to the embodiment. The same portions as those already described in the first embodiment are denoted by the same reference numerals, and duplicate description will be omitted. FIG.
In the plasma display panel holder according to the present embodiment, the main frame connecting joint mounting portion 23 integrally formed on the side surface for connecting and connecting the main frames 2 mounted on the four sides of the PDP 1 is attached to the main frame. A structure is provided for fitting into the fitting flange portion 41 formed on the connection joint 4. Thereby, it is possible to prevent the main frame 2 from falling off the PDP 1 and to prevent the mounting position from shifting.

(Third Embodiment) FIG. 6 shows a third embodiment of the present invention.
FIG. 3 is a structural cross-sectional view for explaining a plasma display panel holder according to the embodiment. The same portions as those already described in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted. Referring to FIG. 6, a plasma display panel holder according to the present embodiment has a main frame connecting joint body integrally formed on a side surface of main frame 2 for connecting and connecting main frames 2 mounted on four sides of PDP 1. A structure is provided in which the portion 23 is fitted into a fitting flange portion 41 formed on the main frame coupling joint 4 to which a circuit mounting structure 61 capable of mounting circuit components can be attached. Thereby, there is an effect that the display module of the PDP 1 can be easily configured.

It should be noted that the present invention is not limited to the above embodiments, and it is clear that the embodiments can be appropriately modified within the scope of the technical idea of the present invention. Further, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to numbers, positions, shapes, and the like suitable for carrying out the present invention. In each drawing, the same components are denoted by the same reference numerals.

[0022]

Since the present invention is configured as described above, the following effects can be obtained. A first effect is that the plasma display panel can be held without using screws for fastening. The reason is that the plasma display panel is held only by the force sandwiched between the upper and lower pairs of plasma display panel sandwiching portions. A second effect is that the plasma display panel can be easily removed by holding and holding the plasma display panel with the plasma display panel holder, and removing the holding force. The reason is that when the plasma display panel is sandwiched between the upper and lower pairs of plasma display panel sandwiching portions, a U-shaped plasma display panel sandwiching force adjusting portion formed on the opposite side from the root portion of the plasma display panel sandwiching portion. This is because the force for narrowing the gap acts on the tip of the plasma display panel, and the force for holding the plasma display panel is increased by inserting the wedge for preventing the narrowing into the tip of the plasma display panel holding force adjustment unit. A third effect is that when the plasma display panel is separated from the plasma display panel holder, only the components constituting the plasma display panel are used alone, so that separation and disposal are facilitated. And the fourth
Is that the number of components can be reduced. The reason is that instead of the conventional plasma display panel holder that was configured with a cover member and a mount member,
This is because the cover member, the mount member, and the like are integrated.
