Definitions

  • the present invention makes it possible to achieve grey scale operation, but it also permits a readable image to be displayed in significantly less time than is taught by prior art EPIDs. It should thus be apparent to those skilled in the art that the above-described techniques and associated apparatus lends itself to many alternate embodiments.
  • the display instead of operating the display in a keyboard mode, the display may be adapted to receive data from a typical telephone line or other transmission media using an analog to digital converter and digital signal pixel generator (not shown).
  • an analog to digital converter and digital signal pixel generator not shown.

Abstract

Affichage électrophorétique (10) assurant la production d'une image en mettant sous tension sélectivement des lignes de grille (16) et de cathode (14) dont chacune des intersections définit un pixel, et en faisant varier la polarisation entre les lignes de façon à amener les particules de pigment en suspension à migrer vers une anode (20) en s'éloignant des pixels alimentés. Des intersections sélectionnées de lignes de grille (16) et de cathode (14) représentant des pixels sont soumises à des séquences de tension pendant un intervalle fixe de temps ce qui produit une image. L'intervalle de temps choisi est inférieur au temps nécessaire pour que les pigments quittent les pixels et l'image est ravivée séquentiellement en resoumettant au moins une fois certains des pixels à des séquences de tension. Cela permet de produire une image lisible beaucoup plus rapidement et d'obtenir des pixels à noircissement incrémentiel puisque les pigments additionnels quittent les intersections sélectionnées pendant les intervalles subséquents de mise sous tension.
