BACKGROUND OF THE INVENTION
The present invention relates to a packaging device for an accessory of a plasma display device, which is known as a thin, lightweight display device having a large screen.
[0002]
[Prior art]
Conventionally, this type of plasma display performs color display by generating ultraviolet rays by gas discharge and exciting phosphors with this ultraviolet rays to emit light. And the display cell divided by the partition on the board | substrate is provided, and it has the structure by which the fluorescent substance layer is formed in this.
[0003]
This plasma display device is roughly classified into an AC type and a DC type in terms of driving, and there are two types of discharge types, a surface discharge type and a counter discharge type. Therefore, at present, the mainstream of plasma display devices is a surface discharge type of a three-electrode structure, and the structure has a pair of display electrodes adjacent in parallel on one substrate, and on the other substrate. It has an address electrode arranged in a direction intersecting with the display electrode, a partition wall, and a phosphor layer. The phosphor layer can be made relatively thick and is suitable for color display using a phosphor.
[0004]
Such a plasma display device can display at a higher speed than a liquid crystal panel, has a wide viewing angle, is easy to enlarge, and is self-luminous so that the display quality is high. Recently, the flat panel display has attracted particular attention and is used for various purposes as a display device in a place where many people gather and a display device for enjoying a large screen image at home.
[0005]
First, the structure of the plasma display panel in the plasma display device will be described with reference to FIG. As shown in FIG. 4, on a transparent front substrate 1 such as a glass substrate, a plurality of stripe-shaped display electrodes 2 paired with a scan electrode and a sustain electrode are formed, and covers the electrode group. Thus, the dielectric layer 3 is formed, and the protective film 4 is formed on the dielectric layer 3.
[0006]
Further, a plurality of rows of stripes covered with an overcoat layer 6 are formed on the rear substrate 5 opposite to the front substrate 1 so as to intersect the display electrodes 2 of the scan electrodes and the sustain electrodes. Address electrodes 7 are formed. On the overcoat layer 6 between the address electrodes 7, a plurality of barrier ribs 8 are arranged in parallel with the address electrodes 7, and a phosphor layer 9 is provided on the side surface between the barrier ribs 8 and on the surface of the overcoat layer 6. Yes.
[0007]
The substrate 1 and the substrate 5 are arranged to face each other with a minute discharge space so that the display electrode 2 and the address electrode 7 of the scan electrode and the sustain electrode are almost orthogonal, and the periphery is sealed, In the discharge space, one or a mixed gas of helium, neon, argon, and xenon is sealed as a discharge gas. Further, the discharge space is divided into a plurality of sections by partition walls 8 to provide a plurality of discharge cells where the intersections of the display electrodes 2 and the address electrodes 7 are located, and each of the discharge cells has red, green and blue colors. The phosphor layers 9 are sequentially arranged one by one so that
[0008]
FIG. 5 shows an electrode arrangement of the plasma display panel. As shown in FIG. 5, the scan electrode, the sustain electrode, and the address electrode have a matrix configuration of M rows × N columns, and M rows are arranged in the row direction. Scan electrodes SCN1 to SCNM and sustain electrodes SUS1 to SUSM are arranged, and N columns of address electrodes D1 to DN are arranged in the column direction.
[0009]
In the plasma display panel having such an electrode configuration, an address pulse is applied between the address electrode and the scan electrode by applying a write pulse between the address electrode and the scan electrode, and after selecting the discharge cell, the scan electrode By applying a periodic sustain pulse that is alternately inverted between the sustain electrode and the sustain electrode, a sustain discharge is performed between the scan electrode and the sustain electrode, and a predetermined display is performed.
[0010]
FIG. 6 shows an example of the overall configuration of a plasma display device incorporating the panel having the structure described above. In the figure, a housing for housing the panel 10 is composed of a front frame 11 and a metal back cover 12, and an opening of the front frame 11 is made of glass or the like that also serves as an optical filter and panel 10 protection. A cover 13 is arranged. Further, the front cover 13 is subjected to, for example, silver vapor deposition in order to suppress unnecessary radiation of electromagnetic waves. Further, the back cover 12 is provided with a plurality of ventilation holes 12a for releasing heat generated in the panel 10 and the like to the outside.
[0011]
The panel 10 is held by adhering to the front surface of a chassis member 14 made of aluminum or the like via a heat conductive sheet 15, and a plurality of circuits for driving the panel 10 to be displayed on the back side of the chassis member 14. A block 16 is attached to form a display unit. The heat conductive sheet 15 is for efficiently transferring the heat generated in the panel 10 to the chassis member 14 to radiate heat. Further, the circuit block 16 includes an electric circuit for performing display driving of the panel 10 and its control, and the electrode lead-out portion led out to the edge portion of the panel 10 extends beyond the four edge portions of the chassis member 14. They are electrically connected by a plurality of extending flexible wiring boards (not shown).
[0012]
Further, a boss portion 14a for attaching the circuit block 16 or fixing the back cover 12 is protruded from the rear surface of the chassis member 14 by integral molding using die casting or the like. The chassis member 14 may be configured by fixing a fixing pin to an aluminum flat plate.
[0013]
