1. A display device comprising:

  • an A/D converter for converting an analog signal into a first digital signal;

    a signal processor for converting said first digital signal to a numerical value of N-radix notation where N≧

    3 and outputting a second signal based on the numerical value of N-radix notation;

    a shift register connected to said signal processor;

    a plurality of first signal lines connected to said shift register wherein a plurality of pulses are applied to corresponding one of said first signal lines based on said second signal;

    a plurality of second signal lines extending across said plurality of first signal lines to define a plurality of pixels; and

    a thin film transistor provided in one of said plurality of pixels,wherein a width and a height of the plurality of pulses are determined based on the second signal.
