ABSTRACT:
A display device for indicating the value of a measured quantity includes a plurality of display elements, each representative of a primary value range. A driving circuit is responsive to a sensor output signal and activates individual ones of the display elements when the sensor output has a value representative of one of the primary value ranges of the measured quantity, and activates adjacent display elements simultaneously when the sensor output signal represents intermediate value ranges of the quantity.
