Abstract

L'invention concerne un dispositif d'affichage à cristaux liquides comprenant des pixels ayant des première et seconde électrodes de pixels auxiliaires, des premières lignes de câblage de capacité auxiliaire pour former des capacités auxiliaires conjointement avec les premières électrodes de pixels auxiliaires, et des secondes lignes de câblage de capacité auxiliaire pour former des capacités auxiliaires conjointement avec les secondes électrodes de pixels auxiliaires. Les premières et secondes lignes de câblage de capacité auxiliaire sont commandées pour avoir leurs polarités individuelles inversées de façon périodique. Les premières inversions de polarité des premières lignes de câblage de capacité auxiliaire et les premières inversions de polarité des secondes lignes de câblage de capacité auxiliaire après les extrémités de balayage des lignes de signal de ligne de balayage sont inversées l'une par rapport à l'autre. Pendant la période de temps (ou la période d'insertion de fréquence du noir), pendant laquelle à la fois les premières et secondes lignes de câblage de capacité auxiliaire ne sont pas inversées en polarité, jusqu'au prochain balayage, les potentiels correspondant à l'affichage noir sont écrits plusieurs fois dans les premières et secondes électrodes de pixels auxiliaires à partir des lignes de signal de données. Ainsi, dans le cas où l'insertion de noir est effectuée dans le dispositif d'affichage à cristaux liquides de type divisé en pixels pour commander les potentiels des lignes de câblage de capacité auxiliaire, il est possible de supprimer l'occurrence de stries transversales.
