Abstract
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.
Claims7
An apparatus comprising:
- a matrix display device with X electrodes and Y electrodes arranged in point-like displays at selected crossing points of the X and Y electrodes;
- and a display device driving system comprising timing signal generating means for controlling the X electrode scanning signals, display signal converter means receptive of a portion of the display information addressed by said timing signal generating means for converting the display information into a portion of the signals for display, a driving circuit for the Y electrodes, memory means for storing the portion of the signals for display for applying to the driving circuit for the Y electrodes, and means controlled by said timing signal generating means for inhibiting the drive to the Y electrodes while information to be stored is being stored in the memory means.
A driving system for a matrix display device having X electrodes and Y electrodes, the system comprising:
- an X-electrode driving circuit;
- an actuatable Y-electrode driving circuit;
- means for applying display data to the Y-electrode driving circuit comprising a single memory for storing the display data and having the outputs thereof connected to the inputs of the Y-electrode driving circuit, and a multiplexer for feeding the display data into the memory;
- and timing signal generating means for effecting the loading of data into the memory during a predetermined transfer time and inhibiting the Y-electrode driving circuit during said transfer time and for effecting the driving of the Y-electrodes by the Y-electrode driving circuit and the simultaneous scanning of the X electrodes by the X-electrode driving circuit after the transfer time.
