To provide a vehicle-purpose display device that reduces the number of wiring connections.SOLUTION: A vehicle-purpose display device comprises: a plurality of display lamps 6 that expresses vehicle information by turning on or off a light source 26; a shift register 21 that inputs a signal by serial communication, and drives to control the display lamp 6 corresponding to the signal; a display instrument 1 that displays by an image; a plot computation circuit 22 that generates the image; and a power source circuit 2b that generates a driving voltage to the display instrument 1 or plot computation circuit 22. The shift register 21 is connected to an enable terminal of the power source circuit 2b, and when a start-up command is included in the signal, outputs an actuation signal enabling an operation start of the power source 2b.SELECTED DRAWING: Figure 3

    【課題】 配線接続数を低減した車両用表示装置を提供する。【解決手段】 車両情報を光源26の点灯または消灯によって表現する複数の表示灯6と、シリアル通信にて信号を入力し、この信号に対応する表示灯6を駆動制御するシフトレジスタ21と、画像にて表示する表示器1と、前記画像を生成する描画演算回路22と、表示器1または描画演算回路22への駆動電圧を生成する電源回路2bと、を備え、シフトレジスタ21は、電源回路2bのイネーブル端子に接続し、前記信号に起動命令を含む場合、電源回路2bを作動開始させる駆動信号を出力する。【選択図】図3
