ABSTRACT:
A display (or printing) device is dynamically capable of displaying an output numeral from a register in a time division manner. The display device is controlled by a control circuitry adapted to provide a blank time between display times of adjacent digit places in a group of display units so that the decrease of display brightness, the display flicker, an overlapped display and instantaneous display disturbance and so on may be prevented. The control circuitry further adapts to suppress insignificant zero which is not to be displayed by the group of display units.
