Abstract

PROBLEM TO BE SOLVED: To reduce a weight and to prevent the cracking of glass by strong vibration or dropping or the like by forming notched parts at plural points of a chassis which is stuck to the rear surface of a PDP panel, is mounted with a circuit board, etc., thereto and is used for mounting the PDP panel to a casing, etc. SOLUTION: The chassis 2 is notched to a square shape at the plural points exclusive of sash bars and is formed to a grid form or is formed to a cross sash bar form by notching the plural points to a band shape. The chassis is otherwise formed to a vertical sash bar form. The plural points are otherwise formed to a diagonal grid form by notching the plural points to a rhombic shape or triangular shape. The chassis 2 is provided with the many notched portions to reduce the area of the PDP panel in contact with the glass 1, by which the degree at which the weight of the chassis 2 is the load of the glass 1 is lowered even when there is the strong vibration or drop in the case of the PDP panel of a large bore. The cracking of the glass 1 may thus be lessened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a PDP (plasma display) panel structure, and more particularly, to a shape of a chassis which is adhered to a rear surface of a PDP panel.

[0002]

2. Description of the Related Art A PDP panel is formed by laminating two sheets of flat glass with an electrode or the like interposed therebetween, attaching an aluminum chassis (about 1.5 mm) to the back surface, and attaching the PDP panel to a housing or the like via the chassis. Is mounted, and the board on which the drive circuit and the like are arranged is mounted on the chassis. The chassis is attached to the back of the glass with a double-sided adhesive sheet, but since the chassis is in close contact with the entire surface of the glass, the weight of the chassis becomes a load on the glass due to strong vibration or dropping etc. Cracks.

[0003]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention has a structure in which a chassis is cut off at a plurality of locations to reduce the weight and the area adhered to the glass surface of a PDP panel, and to reduce strong vibration or vibration. The purpose is to prevent the glass from breaking when dropped.

[0004]

In order to achieve the above object, a PDP panel structure according to the present invention is provided on a chassis for attaching a circuit board and the like and attaching the PDP panel to a housing and the like, which is attached to the back of the PDP panel. Notches are formed at a plurality of places, and are formed so as not to be in contact with the entire surface of the PDP panel.

For this reason, a plurality of portions of the chassis are cut into a rectangular shape to form a lattice.

Alternatively, a plurality of portions are cut into a strip shape to form a vertical bar or a horizontal bar.

Alternatively, a plurality of portions are cut into diamonds or triangles to form an oblique lattice.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 shows a PDP according to the present invention.
FIG. 2 is an exploded perspective view of a main part of one embodiment of a panel structure, and FIGS. 3 and 4 are plan views of main parts of an embodiment of a chassis.

In FIG. 1, reference numeral 1 denotes a glass portion of a PDP panel in which two sheets of flat glass are bonded with an electrode or the like therebetween.
Is a chassis made of aluminum, which is adhered to the back of the glass part 1 of the PDP panel with a double-sided adhesive sheet, 3 is a circuit board on which a drive circuit of the PDP panel is arranged, and 4 is a circuit board 3 with a gap from the chassis 2 It is a spacer for mounting. As shown in FIG. 2, the chassis 2 is formed by cutting out a plurality of portions in a square shape and leaving a cross section, and forming a lattice shape, or as shown in FIG. 3, by cutting out a plurality of portions in a band shape. It is formed in a horizontal bar shape or a vertical bar shape. Alternatively, as shown in FIG. 4, a plurality of portions are cut into rhombuses or triangles to form an oblique lattice shape. As described above, by providing a large number of cut portions in the chassis 2 to reduce the area of the PDP panel in contact with the glass 1, even in the case of a large-diameter PDP panel, strong vibration or dropping occurs,
Of the glass 1 becomes a load of the glass 1 and the breaking of the glass 1 can be reduced.

[0010]

As described above, according to the present invention, P
According to the DP panel structure, since a large number of cutouts are formed in the chassis attached to the back surface of the PDP panel, the load on the glass of the PDP panel is reduced, and even when strong vibration or dropping occurs, the PDP panel is not damaged. Glass breakage can be reduced.
