Title

(EN) ELECTRO-OPTIC DISPLAYS

(FR) AFFICHEURS ÉLECTRO-OPTIQUES

Abstract

(EN)

A method for driving an electro-optic display, the display having at least one display pixel coupled to a storage capacitor, the method include applying a waveform sequence to the at least one display pixel and connecting the storage capacitor to a first bias voltage, and maintaining a last frame voltage level on the display pixel after the completion of the applied waveform.

(FR)

L'invention concerne un procédé de commande d'un dispositif d'affichage électro-optique, le dispositif d'affichage comprenant au moins un pixel d'affichage couplé à un condensateur de mémoire, le procédé consistant à appliquer une séquence de forme d'onde au ou aux pixels d'affichage et à connecter le condensateur de mémoire à une première tension de polarisation, et à maintenir un dernier niveau de tension de trame sur le pixel d'affichage après l'achèvement de la forme d'onde appliquée.
