TECHNICAL FIELD OF THE INVENTION
The present invention relates to a packaging device for a plasma display panel (hereinafter referred to as a panel) in a plasma display device known as a large-screen, thin and lightweight display device.
[0002]
[Prior art]
2. Description of the Related Art In recent years, a plasma display device has attracted attention as a display panel (thin display device) having excellent visibility, and high definition and a large screen have been 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. At present, an AC-type and surface-discharge type plasma display device has become the mainstream due to its characteristics.
[0004]
In such a plasma display device, a panel in which a pair of transparent glass substrates are opposed to each other so that a discharge space is formed therebetween and an electrode group is arranged on the glass substrate, and a chassis member that holds the panel, A panel module is configured by a display drive circuit block attached to the chassis member and applying a signal to the panel to perform display, and the panel module is covered with a housing to complete the product.
[0005]
[Problems to be solved by the invention]
Such a plasma display device has a feature that a large screen is easily realized as compared with other display devices such as a liquid crystal display device and a CRT, and a clearer image is obtained as compared with other large display devices. For this reason, it has attracted attention as an information display device in a place where many people gather and as an image 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 formed by selectively discharging a plurality of discharge cells with plasma. , A large amount of heat is generated during display driving. For this reason, in the plasma display device, it is required to consider a countermeasure for a matter that does not need to 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 large-scale equipment for manufacturing a panel, it is purchased in a state of a panel module from a panel producing manufacturer, and the panel module is added to the panel module. In addition to incorporating other circuit blocks that are not mounted in a plasma display device, they are also put into a housing to complete a plasma display device. In addition, the panel is transported in a state where the chassis is made of aluminum or the like instead of a single panel. Since the glass is fixed to the chassis, there is no need to worry about the transportation and the strength.
[0008]
However, when trying to transport a single panel without a chassis, since the panel is made of glass, the strength is very weak without the chassis, and how the flexible wiring board pulled out of the panel is handled. The big issue was how to pack.
[0009]
The present invention has been made in view of such a problem, and an object of the present invention is to provide a packing device that can prevent damage during transportation of a panel.
[0010]
