Title
(EN) METHODS FOR REDUCING EDGE EFFECTS IN ELECTRO-OPTIC DISPLAYS
(FR) PROCEDE DE REDUCTION D'EFFETS DE BORD DANS DES AFFICHEURS
Abstract
(EN) Edge effects in electro-optic displays are reduced by (a) ensuring that during rewriting of the display, the last period of non-zero voltage applied all pixels terminates at substantially the same time; and (b) scanning the display at a scan rate of at least 50 Hz.
(FR) Ont réduit les effets de bord dans des affiches rétro optiques qu'elles (a) en faisant en sorte que durant la réécriture de l'afficheur, la dernière période de tension non nulle appliquée à tous les pixels se termine sensiblement en même temps et,(b) en balayant les afficheurs à une vitesse de balayage d'au moins 50 Hz.
