ABSTRACT:
A multi-tone display matrix display device including a matrix display panel having a matrix having plural X and Y direction signal lines lying at right angles to each other, intersecting points on the matrix being pixels of an image, an X direction driving section for sequentially scanning X direction signal lines to provide image signals, a Y direction driving section for driving the Y direction signal lines in synchronism with the scanning of the X direction signal lines to sequentially provide select signals to the Y direction signal lines, an A-D converter section for converting an analog signal into a digital signal, a voltage generating section for generating signals at plural voltage levels, and a selector section for selecting an output signal from the voltage generating section based on the output from A-D converter section and providing to output to the X direction driving section as an image signal.
