1. A driving system, for use in a displaying device capable of gradation display, comprising:

  • a pseudo bit-depth extension block for increasing visible gradation levels by (i) adding a noise pattern to upper-8-bits of input m-bit data (m being an integer not less than

         9), and (ii) outputting as output data upper-n-bit (n being an integer not less than 8 and less than m) of data obtained by adding the noise pattern to the upper-8 bits of the input m-bit data;

    an overshoot-driving block for performing overshoot-driving in display operation, an amount of the noise pattern being not more than 1 in 8-bit data, and the overshoot-driving block for performing calculation on 8-bit basis.
