て一体化したことを特徴とするものである。 In this invention, one or more display dots are provided on the front side of a strip-shaped control and drive printed wiring board, while thin control and drive electronic components are attached to the back side and arranged on a base sheet. This control and drive printed wiring board is arranged in a row or part of a row of display dots, and a front sheet is arranged on the front side of the base sheet, and a rear sheet is placed on the back side of the base sheet. be.

〔実施例〕〔Example〕

以下、本考案を図示の実施例に基づいて詳細に
説明する。 Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

ケツト）８を設けている。 1 to 3 show an embodiment of the present invention, in which a plurality of LEDs 2 are attached to a small printed wiring board 1 to serve as display dots. The display dot is
They are arranged in a matrix on the base sheet 3. In that case, it is not attached to a part of one column (or one row), but a strip-shaped printed wiring board 4 is placed instead, display dots (one or more) made up of a plurality of LEDs 5 are provided on the front side, and a control dot is provided on the back side. and drive electronic components 6 are attached. This electronic component 6
It uses flat package ICs and resistors to make it thin. Further, a lead wire 7 is connected to the printed wiring board 4, and a connector (socket) 8 is provided at the tip of the lead wire 7.
