Abstract
According to the present invention, the driving timing for each segment in a segment type digital display unit can be controlled independently on the basis of either one or both of the lighting history of each segment stored in a memory section and a detected temperature from a temperature detector mounted near segments. Therefore, the discriminatability particularly at low temperatures can be improved with little influence of the temperature and lighting history of segments.
