Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packing device for a plasma display panel (hereinafter referred to as a panel) in a plasma display device known as a thin, lightweight display device having a large screen.
[0002]
[Prior art]
In recent years, plasma display devices have attracted attention as display panels (thin display devices) with excellent visibility, and higher definition and larger screens are being promoted.
[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, AC-type and surface-discharge-type plasma display devices are mainly used.
[0004]
In such a plasma display device, a pair of transparent glass substrates are arranged to face each other so that a discharge space is formed therebetween, and a panel in which an electrode group is arranged on the glass substrate, a chassis member that holds the panel, A panel module is constituted by a display drive circuit block that is attached to the chassis member and applies a signal to the panel to perform display, and the panel module is covered with a casing to complete a finished product.
[0005]
[Problems to be solved by the invention]
Such a plasma display device has a feature that it is easy to realize a large screen as compared with other display devices such as a liquid crystal display device and a CRT, and a clear image can be obtained as compared with other large display devices. For this reason, it is attracting attention as an information display device in a place where many people gather, and as a video device that can enjoy powerful images at home.
[0006]
On the other hand, while this plasma display device is easy to realize a large screen, a large glass substrate is required as a glass substrate which is a main component of the panel, and an image is obtained by selectively plasma-discharging a plurality of discharge cells. Therefore, a lot of heat is generated during display driving. For this reason, in the plasma display device, it is required to consider countermeasures for matters that may not be considered in other display devices.
[0007]
By the way, in recent years, in this type of plasma display device, since it is necessary to prepare a large-scale facility for manufacturing the panel, it is purchased in the form of a panel module from the manufacturer that produces the panel, and the panel module In addition, other circuit blocks that are not mounted on the circuit board are incorporated, and the circuit blocks are put into a housing to complete a plasma display device. Moreover, since the panel is transported with a chassis made of aluminum or the like attached to the panel, and the glass is fixed to the chassis, there is no concern about the transportation and the like in terms of strength.
[0008]
However, when transporting a single panel without a chassis, the panel is made of glass, so it is very weak in strength without a chassis, and how can the flexible wiring board drawn out of the panel be used? Whether to pack was a big problem.
[0009]
This invention is made | formed in view of such a subject, and it aims at providing the packing apparatus which can prevent the damage at the time of transport of a panel.
[0010]

In order to solve the above-described problems, the present invention provides a packaging member having plate-like first and second trays for holding a panel by overlapping the panels so as to sandwich the panel, and four corners of the first and second trays. And a corner molded product that detachably couples the first and second trays and abuts against the corners of the panel to regulate the position of the panel.
[0011]
