本発明は大容量液晶表示素子駆動用回路の実装方法に関

あった時、基板からパッケージを離し、実装し直すには
非常に時間がかかった。In recent years, 200 dots x 640 dots, 400 x 640 dots, etc. x rx crystal display elements have come into practical use. Along with this, the number of drivers installed in liquid crystal display devices has also increased significantly, requiring a large mounting area. In addition, with large capacity liquid crystal display elements, driving duty
Therefore, from the viewpoint of appearance, a liquid crystal display device with a backlight is desired. Connection is difficult. Furthermore, in the conventional example, when a flat package IC mounted on a rigid board is defective, it takes a very long time to separate the package from the board and remount it.
そこで本発明はこのような問題点全解決するもので、そ

実装方法を提供するところにある。Therefore, the present invention is intended to solve all of these problems.The purpose of the present invention is to reduce the total mounting area of a driver for driving a liquid crystal display element, to easily replace a defective driver, and to further improve the performance of a transmissive liquid crystal display. The purpose is to provide a driver implementation method that can be used in devices.

It was folded into the inside of the liquid crystal display element 7 as shown in FIG.

、本発明でに約５ｆＩｍとなった。In the conventional driver mounting method, the substrate area was equal to or larger than that of a liquid crystal display element, but in the present invention, the area is less than 175 times that of a liquid crystal display element. Furthermore, regarding the thickness, the thickness of the conventional liquid crystal display device was about 10, but the thickness of the present invention is about 5 fIm.

によシ、これが解決できた。[Example 2] In Example 1, as shown in FIG. 3, the flexible substrate 1 was not bent as shown in FIG. 3, but was spread out as shown in FIG. By placing cold cathode tubes in the backlight, a good transmission type liquid crystal display device was realized. Conventionally, when a buffer flyer was disposed between the liquid crystal display element and the rigid substrate, it was extremely difficult to connect the liquid crystal display element and the rigid substrate, but this problem has been solved by the present invention.

できた。[Example 3] In Examples 1 and 2, when the liquid crystal display element 7 and the flexible substrate 1 were all connected, it was found that one of the drivers was defective, so the flexible substrate of that component was cut, A repair flexible board 8 shown in FIG. 4 was placed in the cut portion, and the lands 6 were connected with solder. In the conventional example, it took a very long time to replace a flat package IC, but in the present invention, it could be replaced in a short time.

装置の作成も容易になった。As described above, according to the present invention, the entire liquid crystal display device can be made extremely thin, small, and light, and furthermore, it has become easy to create a transmission type liquid crystal display device.
又、不良ＩＣの取シ変えも短時間でできるようになった
。In addition, it has become possible to replace defective ICs in a short time.
