[0001]

The present invention relates to a liquid crystal display panel,
The present invention relates to an electrical component inspection socket used for inspecting the display quality of a display panel such as an electroluminescence panel and a plasma display panel, or for inspecting an electrical component such as an operation check of a semiconductor integrated circuit (IC).

[0002]

2. Description of the Related Art Generally, various display panels such as an electric component, for example, a liquid crystal display panel, an electroluminescence panel, and a plasma display panel have a large number of electrodes on a substrate. Therefore, in the manufacturing process of the display panel, the display panel before connection of the peripheral circuit such as the driving IC tab is inspected for a display defect portion, a display quality, and the like. When inspecting the display or performance of this type of display panel, an electrical component inspection socket having a contact member called a display panel inspection socket for supplying driving power to the display panel is used. I have.

As an example of this type of socket for electrical component inspection, a contact member having a predetermined pattern of contact terminals formed on one surface of a film substrate made of an insulating material is disposed on a plate. A large number of electrode terminals on the substrate of the electric component and the contact terminals of the contact member are required by sandwiching the electric component mounted on the contact member of the plate with a clamp member having a substantially U-shaped cross section. The clamper is configured so as to be individually contacted one-to-one with the contact pressure, and the clamp member is slidable between a position for pressing the back side of the electric component and a position for detachably opening the electric component. A so-called type has been proposed.

As another example of an electrical component inspection socket, an electrical component inspection socket using two plates has been proposed. This is because two plates sandwiching the electric component are fastened by a fastener, so that the contact terminals of the contact member provided on one of the plates and a large number of electrode terminals on the substrate of the electric component at the time of inspection are one. It is referred to as a plate type configured to be individually contacted at a required contact pressure in a one-to-one relationship.

[0005]

In recent years, the cost of various products has been required to be reduced, and the socket for electrical component inspection has also been required to be reduced in cost.

However, in the above-mentioned conventional socket for inspecting electric components, for example, the entirety of the so-called black-and-white solid lighting, which turns on / off all pixels of the liquid crystal display section of the liquid crystal display panel as electric components. When performing the inspection, a device having a contact member formed with contact terminals that individually contact one to one with a large number of electrode terminals of the liquid crystal display panel is used. Each time the accuracy changes, a contact member having a contact terminal conforming thereto is required. For this reason,
There was a problem that the cost of the contact member was increased, and as a result, the cost of the socket for inspecting electrical components was increased.
Furthermore, with the recent increase in the precision of the electrode terminals of electrical components, there has been a demand for higher precision of the contact terminals, and such higher precision of the contact terminals has also increased the cost of the contact members. In addition, there has been a problem that the cost of the socket for inspecting electrical components is increased.

As a socket for inspecting an electric component which can cope with such a problem, a contact terminal for making contact with a large number of electrode terminals of the electric component is formed by a conductive rubber member extending along the arrangement direction of the electrode terminals. Although a contact member is conceivable, such a contact member can reduce the cost of the contact member and reduce the cost of the socket for electrical component inspection, but corresponds to the increase in the precision of the electrode terminals of the electrical component. There was a problem that it was not possible.

That is, a conventional electric component, for example, a liquid crystal display panel 1 as a display panel shown in FIG.
A substantially rectangular liquid crystal display unit 3 is formed so as to protrude from one surface 2a of a substrate 2 formed in a substantially rectangular plane by an insulating material such as glass. On one side 2a of the substrate 2, a large number of electrode terminals 4 are divided into blocks for each drive module along the side of the liquid crystal display section 3, and are arranged in parallel with each other. In this liquid crystal display panel 1, a long side located on the lower side of the substrate 2 shown in the lower part of FIG.
The plurality of electrode terminals 4 are arranged and formed on two sides of a short side located on the left side of FIG.

As shown in FIG. 17, for example, the majority of the electrode terminals 4 in the central part in the arrangement direction of the electrode terminals 4 in the left-right direction of FIG. First signal input terminal 4a used for inputting a signal connected to an individual electrode (not shown) of liquid crystal display panel 1
And these first signal input terminals 4a provide
A first input section 4A is formed.

In addition, the first electrode terminal of the plurality of electrode terminals 4
A plurality of, for example, three electrode terminals 4 adjacent to the left and right ends in FIG. 17 of the first signal input terminal 4a constituting the input section 4A are non-signal input terminals 4b to which signal input is impossible. The non-signal input terminal 4b forms a non-input section 4B.

Further, among the many electrode terminals 4, FIG.
The electrode terminals 4 located at the left and right ends in the arrangement direction of the electrode terminals 4 shown in the left and right direction and adjacent to the left and right ends of the non-signal input terminal 4b constituting the non-input portion 4B in FIG. The second signal input terminal 4c is connected to a common electrode (not shown) or the like.
Constitutes the second input unit 4C. Note that a signal different from the signal input to the first input unit 4A is input to the second input unit 4C.

When a contact member having a contact terminal made of conductive rubber is used for the configuration of the electrode terminal 4 of the liquid crystal display panel 1 as such an electric component, the electrode divided into blocks for each drive module is used. After configuring the wiring so that the second input portions 4C of the terminals 4 are combined into one location, at the time of inspection, only the first input portions 4A of the electrode terminals 4 are provided with contact terminals made of conductive rubber. It will be set as the structure made to contact.

However, in such a configuration, the first signal input terminal 4a of the large number of electrode terminals 4
In some cases, it is not possible to form a contact terminal that comes into contact only with the first input unit 4 </ b> A configured as described above. That is, the conductive rubber may be compressed and elastically deformed in the contact state at the time of inspection, and the length of the contact terminal made of the conductive rubber becomes shorter than the length of the first signal input terminal 4a in the arrangement direction. The contact terminal does not contact a part of the first signal input terminal 4a, or conversely, the length of the contact terminal is longer than the length of the first signal input terminal 4a in the arrangement direction. There is a problem that the 1 input unit 4A and the non-signal input unit 4B are short-circuited.

Therefore, if the contact terminals are made only of conductive rubber, a high-precision terminal cannot be obtained, and it is not possible to cope with a high-precision electrode terminal 4 of the liquid crystal display panel 1. Was. In the case of using a contact member having a contact terminal made of such conductive rubber, the second input portions 4C of a large number of electrode terminals 4 divided into blocks for each drive module are combined into one location. There is a problem that such a wiring configuration is actually extremely difficult.

The present invention has been made in view of the above points, and an object of the present invention is to provide an inexpensive socket for inspecting electric components, which can cope with higher precision of electrode terminals of electric components. .
