Furthermore, recently, liquid crystal display panels have become larger in size, their uses have been expanded, and their demand has been rapidly increasing. As liquid crystal displays and panels become larger, the number of terminals connected to the drive circuit board increases, and conductive rubber connectors also need to be made longer. Therefore, when attaching a large liquid crystal display panel to the drive circuit board, it is done using an outer frame that fixes the liquid crystal display panel.
Since the outer frame is brought into direct contact with the surface of the liquid crystal display panel, if the outer frame is deformed such as warping, the contact area between the outer frame and the surface of the liquid crystal display panel becomes uneven.

おいても重大な欠点があった。In particular, when the conductive rubber connector is made long, the crimping force per unit area of the conductive rubber connector at the contact part may be significantly uneven, or there may be a partial disconnection in the electrical connection between the liquid crystal display panel and the drive circuit board. There were serious drawbacks such as the occurrence of Furthermore, when attaching a large liquid crystal display panel to a drive circuit board, with conventional conductive rubber connectors, pressure is applied to the conductive rubber connector even when the conductive rubber connector is pressed onto the liquid crystal display panel by the outer frame. There were also serious drawbacks in terms of reliability, such as the dispersion of the bonding force, weakening of the pressure bonding force, and weakening of durability against vibrations and shocks.

When attaching the liquid crystal display panel 3 to the drive circuit board 4, conductive rubber connectors are first inserted into the terminal portions of the liquid crystal display panel 3. In this state, the conductive rubber connector adheres to the terminal section due to the adhesiveness of the rubber on the back surface of the terminal section. Next, the liquid crystal display panel 3 fitted with the conductive rubber connector is placed in a position correctly corresponding to the connection terminals on the drive circuit board 4 and fixed to the drive circuit board 4 by the outer frame 5.

、蛇行などの変形、転倒が生じない。That is, when using the conductive rubber connector of the present invention, since the conductive rubber connector is installed on the drive circuit board 4 after integrating the liquid crystal display panel 3, the liquid crystal display panel 3 and the drive circuit board 4 of the conductive rubber connector are There will be no misalignment, no deformation such as meandering, and no overturning.

が解消される。In addition, when fixing the liquid crystal display panel to the drive circuit board 4 using the outer frame 5 after installing the liquid crystal display panel in a position that correctly corresponds to the connection terminals on the drive circuit board 4, the outer frame 5 made of a hard material may be used to connect the terminals of the liquid crystal display panel 3. In order to crimp the flexible conductive rubber connector fitted into the outer frame 5, the crimp force per unit area of the conductive rubber connector remains constant even if the outer frame 5 is deformed such as warping, and the liquid crystal display due to the deformation of the outer frame 5 remains constant. Partial disconnection occurs in the electrical connection between the display panel 3 and the drive circuit board 4◆

回路基板４との電気的接続は、より一層容易になる。As a second embodiment, the conductive rubber connector shown in FIG. 2, in which the upper part of the U-shaped conductive rubber connector is semicircular, is inserted into the terminal part of the liquid crystal display panel 3, and the conductive rubber connector and the liquid crystal display panel 3 are assembled. After being integrated, it is attached to the drive circuit board 4 and fixed with the outer frame 5. When the conductive rubber connector shown in FIG. 2 is used, since the upper part of the U-shaped conductive rubber connector is semicircular, the central part of the cross section of the conductive rubber connector is more strongly crimped. Therefore, since the conductive part 2 of the conductive rubber connector is located at the center of the cross section of the conductive rubber connector, the conductive part 2 is more strongly crimped, that is, the compression ratio of the conductive part 2 is equal to that of the non-conductive rubber 1 Therefore, the electrical connection between the liquid crystal display panel 3 and the drive circuit board 4 using the conductive rubber connector becomes even easier.

。The liquid crystal display panel 3 is sandwiched between conductive rubber connectors, and when securing it with the outer frame 5, only the conductive rubber connector is inserted into the outer frame 5.
The drive circuit board 4 is sandwiched between the drive circuit board 4 and the drive circuit board 4. Therefore, even if vibrations and shocks are applied to the outer frame 5 and the drive circuit board 4 from the outside, the vibrations and shocks are absorbed by the conductive rubber connectors that sandwich the terminal portions of the liquid crystal display panel 3. Therefore, displacement of the liquid crystal display panel 3 due to vibration or impact can be prevented. Therefore, reliability against mechanical shocks such as vibrations and impacts is significantly improved. Although the present invention has been described above as an embodiment of a device using a large-sized liquid crystal display panel, it is clear that the same effects as the present invention can be achieved in a device using a small-sized liquid crystal display panel.
