Abstract

A flat display unit having a plurality of display pixels provided at intersecting points of scanning electrodes and signal electrodes that are arranged in the form of a matrix. Among the scanning electrodes and the signal electrodes, at least the scanning electrodes are driven by separate drive circuits from the terminals on both sides of the electrodes. The invention further provides a method of driving the flat display unit.
