Abstract

A digital display device which has a delay circuit for operating a segment on-off driver so that when the ambient temperature at the time of renewing display is lower than a predetermined value, an OFF signal is sent to an ON segment and then, after the lapse of a predetermined time, an ON signal is sent to an OFF segment. Consequently, the overlap time between the segment to which an OFF signal was newly transmitted and the segment to which an ON signal was newly transmitted, can be made very short or eliminated whereby the discriminatability is improved to prevent misunderstanding of the display.
