Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a liquid crystal display panel,
The present invention relates to a display panel inspection socket suitable for inspection of lighting conditions and display quality of various display panels such as an electroluminescence panel and a plasma display panel.

[0002]

2. Description of the Related Art Generally, a display panel such as an electroluminescence panel or a liquid crystal display panel has a large number of electrode terminals on a substrate. For this reason, in the manufacturing process of the display panel, inspection for a display defect portion, display quality, and the like is performed before connection with a peripheral circuit such as a driving IC tab. When inspecting the display or performance of such a display panel, a display panel inspection socket is used to electrically connect the electrode terminals of the display panel to an external drive circuit.

[0003] Such a conventional display panel inspection socket has, for example, a pair of plates, and on one of the plates, a substantially square panel mounting portion for arranging the display panel. A contact film having a contact terminal pattern for making electrical contact with each electrode terminal of the display panel arranged on each side of the panel mounting portion is fixed by fixing means. ing. The number of the contact films is determined according to the positions and the number of the electrode terminals of the display panel. For example, a plurality of contact films are often arranged on one side. At this time, the pitch between adjacent contact films had to be adjusted to match the pitch of each contact terminal, and a careful operation was required.

When the position of the contact film is determined and fixed on the plate, the contact film is not usually removed until the contact film is damaged. Thereafter, the electrode terminals of the display panel are adjusted so as to be in contact with the contact terminals of the contact film, and then the other plate is overlapped and both plates are fastened by fastening means. As the fastening means, for example, a slide plate having a leaf spring that slides along the plate surface or a fastening screw is used. The slide plate has a leaf spring and is slidably mounted on the upper surface of the other plate (upper plate). A hook member provided on one plate (lower plate) and a leaf spring portion Are engaged to fasten the pair of plates. That is, after the other plate (upper plate) is overlaid on one plate (lower plate), the slide plate attached to the upper surface of the other plate is slid and moved through the through hole of the other plate. Then, a pair of plates is fastened by engaging a leaf spring of a slide plate with a tip end of a hook member provided on one plate facing the upper surface of the other plate. The contact terminal of the contact film is brought into contact with a required contact pressure (see JP-A-11-95680).

In the case of using the fastening screw,
The contact terminals of the contact film and the electrode terminals of the display panel are brought into contact with a required contact pressure by tightening fastening screws at predetermined positions of the respective plates.

[0006]

However, in conventional display panel inspection sockets, a plurality of contact films may be fixed on the plate corresponding to the electrode terminals formed on one side of the display panel. However, because it was difficult to fine-tune the pitch between adjacent contact films, if one of the contact films was damaged, even if only the damaged contact film was replaced, the original contact film was restored. It is almost impossible to arrange them in a positional relationship, and in fact, repair by replacing only such damaged contact films is practically impossible.

Further, since the gap between the adjacent contact films is as small as about 1 mm, the intermediate position between the two cannot be pressed by a fixing screw or the like. for that reason,
The contact film cannot be firmly fixed on the plate, and the fixing position is shifted, so that the pitch of the contact terminals may be shifted.

Further, in the conventional display panel inspection socket, when the position adjustment for bringing the electrode terminals of the display panel into contact with the contact terminals of the contact film is performed, the display panel is moved by moving the display panel. Since there was no mechanism for finely adjusting the position, the position could not be easily determined. In particular, when inspecting a small display panel, the position adjustment is difficult and inconvenient.

Furthermore, in a conventional display panel inspection socket using a slide plate as the plate fastening means, a slide plate having substantially the same size as a pair of plates is slid from a release position to a pressing position. However, there is a problem that the socket system becomes large and the operability is poor.

On the other hand, in a display panel inspection socket using a compression screw as a fastening means for the plate, it is easy to obtain a uniform pressing force if the number of fastening screws is large, but it is troublesome to operate the fastening screws. And the workability is reduced. In addition, if the number of fastening screws is small, the plate to be fastened tends to bend, and the pressing force due to the fastening becomes uneven. And
If the thickness of the plate is increased to prevent the plate from bending, the weight of the socket increases, and the workability of inspecting the display panel is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is possible to securely fix a contact film and to easily replace and align the contact film. An object of the present invention is to provide a display panel inspection socket capable of improving the operability by simplifying an alignment structure and further improving the operability by simplifying and miniaturizing a fastening structure of a pair of plates.

And a panel position adjusting member attached to the panel positioning plate. By adopting such a configuration, by operating the panel position adjusting member, each panel side support elastic member moves the display panel in the front-rear and left-right directions while opposing the pressing force of the panel side pressing plate. The electrode terminal of the display panel can be easily and reliably brought into contact with the contact terminal of the contact film.

According to a fifth aspect of the present invention, in the fourth aspect, the stopper plate for preventing the panel side-surface pressing plate from moving toward the display panel is swingable and its support shaft is used as a fulcrum. A pressing release maintaining projection is provided at a position where the panel side pressing plate can be engaged with the stopper plate, and the pressing force against the display panel is released. If so, the pressing release maintaining protrusion is engaged with the stopper plate to prevent the panel side surface pressing plate from moving to the display panel side, and when applying a pressing force to the display panel. Then, the stopper plate is rocked against the urging force to release the engagement with the pressing release maintaining projection and the panel side pressing plate is moved to the display panel side. It lies in the fact that you have configured. By adopting such a configuration, when the display panel is attached or detached, the panel-side pressing plate may be moved so that the press-release maintaining projection is engaged with the stopper plate, and the display panel is again mounted. When the display panel is pressed and held, it is sufficient to move the panel side pressing plate so as to release the engagement between the pressing release maintaining projection and the stopper plate. be able to.
