ABSTRACT:
A display apparatus receives analogue signals representing the detected values of the number of revolutions per minute of an automobile's engine, the residual fuel, the automobile's speed, the temperature at the various portions of the automobile and the like. An analogue signal desired for display is selected from those analogue signals by means of a switching device. The selected signal is applied to a common terminal. A plurality of light emitting diodes are connected between the common terminal and the terminals of a voltage-dividing device consisting of a plurality of resistors thereby to display the detected values.
