Abstract
A circuit for producing a numerical signal representative of the value of the physical parameter which is to be displayed and which can assume a given number of values. The signal is applied to a decoder for controlling the display cell. The decoder is so arranged as to render visible a single display element for certain values of the numerical signal and two adjacent elements for other values. The cell therefore comprises a small number of display elements than there are different values to be displayed.
