Patent ID: 6900924

Claim:
An electrophoretic display, comprising: a display substrate and a rear substrate disposed with a predetermined spacing therebetween, an insulating liquid and a plurality of electrophoretic particles provided in the predetermined spacing, a first electrode disposed along said rear substrate for each pixel, a second electrode and a third electrode which are disposed at a boundary between adjacent pixels, voltage application means for applying voltages to said first to third electrodes, said voltage application means including reset means for collecting said electrophoretic particles at a peripheral portion of an associated pixel by applying a voltage for attracting said electrophoretic particles toward said second electrode, writing means for moving said electrophoretic particles collected by said reset means in a pixel area along said rear substrate by applying a voltage for attracting said electrophoretic particles toward said first electrode, and write limiting means for collecting a part of said electrophoretic particles at a peripheral portion of the associated pixel different from that with respect to said reset means by applying a voltage for attracting said electrophoretic particles toward said third electrode, and control means for controlling a gradation level by adjusting timing of application of the voltage for attracting said electrophoretic particles toward said first electrode by said writing means and the voltage for attracting said electrophoretic particles toward said third electrode by said write limiting means.
