ABSTRACT:
A luminescent analog-display device having a plurality of segment anodes adapted to emit light when bombarded with electrons and divided into a plurality of groups, control electrodes provided independently of one another for the respective groups, a section for generating first and second timing pulses out of phase with each other, sections for giving a driving signal in response to the first timing pulse to the segment anodes corresponding in number to the numerical value of the least significant digit of the numerical information to be displayed and for giving a driving signal to all the segment anodes in response to the second timing pulse, and sections for giving a driving signal in response to the first timing pulse to the control electrode corresponding to the group for representing the numerical value of the least significant digit of the numerical information and also for giving a driving signal in response to the second timing pulse to the control electrodes associated with the groups corresponding to the numerical value of the higher-column significant digits of the numerical information.
