Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packaging device for accessories of a plasma display device, which is known as a large screen, thin, and lightweight display device.
[0002]
[Prior art]
Conventionally, this type of plasma display generates an ultraviolet ray by gas discharge and excites a phosphor with the ultraviolet ray to emit light, thereby performing color display. Then, a display cell partitioned by a partition is provided on the substrate, and a phosphor layer is formed on the display cell.
[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. At present, the mainstream of plasma display devices is a surface discharge type having a three-electrode structure, which has a pair of display electrodes adjacent to each other in parallel on one substrate, and a structure on the other substrate. It has address electrodes arranged in a direction intersecting the display electrodes, partition walls, and a phosphor layer. The phosphor layer can be made relatively thick, and is suitable for color display using phosphors.
[0004]
Such a plasma display device is capable of high-speed display as compared with a liquid crystal panel, has a wide viewing angle, is easy to increase in size, and has a high display quality because it is a self-luminous type. Recently, flat panel displays have attracted particular attention, and have been used for various purposes as display devices at places where many people gather and display devices for enjoying large-screen images 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. 3, a plurality of rows of stripe-shaped display electrodes 2 formed of pairs of scan electrodes and sustain electrodes are formed on a transparent front substrate 1 such as a glass substrate, and cover the electrode group. A dielectric layer 3 is formed as described above, and a protective film 4 is formed on the dielectric layer 3.
[0006]
A plurality of rows of stripes covered with an overcoat layer 6 are provided on a rear substrate 5 opposed to the front substrate 1 so as to intersect with the display electrodes 2 of scan electrodes and sustain electrodes. Address electrodes 7 are formed. A plurality of partitions 8 are arranged on the overcoat layer 6 between the address electrodes 7 in parallel with the address electrodes 7, and the phosphor layers 9 are provided on the side surfaces between the partitions 8 and on the surface of the overcoat layer 6. I have.
[0007]
The substrate 1 and the substrate 5 are opposed to each other with a minute discharge space therebetween so that the display electrode 2 of the scan electrode and the sustain electrode and the address electrode 7 are substantially orthogonal to each other, and the periphery thereof is sealed. In the discharge space, one or a mixed gas of helium, neon, argon, and xenon is sealed as a discharge gas. The discharge space is partitioned into a plurality of partitions by partition walls 8, so that a plurality of discharge cells are provided at intersections between the display electrodes 2 and the address electrodes 7, and each of the discharge cells has a red, green, and blue color. The phosphor layers 9 are sequentially arranged for each color such that
[0008]
FIG. 4 shows an electrode arrangement of the plasma display panel. As shown in FIG. 4, the scan electrodes, sustain electrodes, and address electrodes have a matrix configuration of M rows × N columns, and M rows × N columns 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 discharge is performed between the address electrode and the scan electrode by applying a write pulse between the address electrode and the scan electrode, and after selecting a discharge cell, the scan electrode A sustain discharge is performed between the scan electrode and the sustain electrode by applying a periodic sustain pulse that is alternately inverted between the scan electrode and the sustain electrode, thereby performing a predetermined display.
[0010]
FIG. 5 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 accommodating a panel 10 is composed of a front frame 11 and a metal back cover 12, and an opening of the front frame 11 has a front surface made of glass or the like which also serves as an optical filter and protects the panel 10. A cover 13 is provided. The front cover 13 is coated with, for example, silver 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 bonding a 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 display of the panel 10 are provided on the rear side of the chassis member 14. A block 16 is attached, which constitutes a display unit. The heat conductive sheet 15 is for efficiently transmitting the heat generated in the panel 10 to the chassis member 14 and radiating the heat. Further, the circuit block 16 includes an electric circuit for performing display driving of the panel 10 and controlling the same, and the electrode drawing portion drawn to the edge portion of the panel 10 extends beyond the four edge portions of the chassis member 14. It is electrically connected by a plurality of extending flexible wiring boards (not shown).
[0012]
A boss 14a for attaching the circuit block 16 and fixing the back cover 12 is formed on 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]
