摘要:
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.
摘要:
A driving circuit for a luminescent display tube having a plurality of segment anodes arranged in a predetermined direction and each provided with a luminescent material layer, the segment anodes being divided into a plurality of groups each having the same number of the segment anodes, the corresponding segment anodes of the respective groups being connected in common, and a plurality of control grids provided separately for the respective groups, comprising a scanning pulse generating circuit section for generating scanning pulses for successively driving the segment anodes connected in common, and a control circuit section adapted to receive the scanning pulses from the scanning pulse generating circuit section and input numeric signals and adapted to give driving signals to the control grids according to the input numeric signals.
