Description

  The present invention relates to a method for packing a display panel module in a display device such as a plasma display device known as a thin, lightweight display device having a large screen.

  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.

  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.

  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 board 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.

  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.

  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.

  By the way, in recent years, in this kind of plasma display device, since it is necessary to prepare a large-scale facility for manufacturing the panel, it is purchased in the state of the panel module from the manufacturer that produces the panel, and is mounted on the panel module. Other drive circuit boards that are not installed are assembled 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.

  On the other hand, as shown in Patent Document 1, it is also considered to transport the panel as a single item, but since the panel is made of glass, it is very weak in the absence of a chassis, and from the panel. It was a big subject of how to pack the drawn-out flexible wiring board.
