Abstract
A procedure for the display of measured quantities as a bargraph with the help of a row of addressable display elements, whereby the display elements are interconnected on one side into contiguous groups and on the other side according to like position within each group. Either the on-groups, in which all display elements are to be excited, or the mixed group, in which only a part of the display elements are to be excited, are addressed in a rapid alteration imperceptible to the eye of the beholder. The amplitude of the driving voltage across display elements in the mixed group is zero during the strobe interval for the on-groups.
