摘要： In a display circuit for actuating a display having plural liquid crystal segments or luminescent diodes, an improved comparator is provided for determining the number of the display segments to be energized and activated in accordance with an analogue input voltage. The analogue input voltage is applied to one terminal of a resistance having plural resistors connected in series, the other terminal of which is grounded. The comparator is composed of an integrated circuit of MOS type which has plural logical circuits. Each of one input terminals of the logical circuits is connected to a corresponding one of junctions of the resistors connected in series. Each logical circuit of the comparator provides "1" output signal when the voltage at the corresponding junction exceeds a threshold value thereof. An actuator, which is constructed with exclusive OR gates or transistors, energizes the liquid crystal segments or the luminescent diodes in response to the "1" output signals from the comparator.

摘要： 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.
