A driving system for matrix display device having X electrodes and Y electrodes for displaying at selected crossing points of the electrodes is provided with a timing signal generator for controlling the X electrode scanning signals, a display signal converter receptive of a portion of display information addressed by a signal from the time signal generator for converting the display information into a portion of the signals for display. A memory device stores the portion of the signals for display and applies the same to the driving circuit for the Y electrodes. The drive to the Y electrodes is inhibited while information to be stored is being stored in the memory.
