The present invention provides a multiplexed matrix alternating current electroluminescent display, comprising an array of matrix addressed capacitively switchable electroluminescent pixels, with each capacitively switchable electroluminescent pixel including an electroluminescent pixel and a circuit element connected in electrical series with the electroluminesent pixel. The circuit element is switchable between an electrically insulating capacitive state and an electrically conducting state depending upon a voltage applied across the capacitively switchable electroluminescent pixel. The matrix multiplexed electroluminescent (EL) display with the low capacitance switching device in electrical series with the electroluminescent pixels reduces column displacement currents, thereby reducing power consumption. Refresh times can also be reduced so that the size and resolution of passive matrix electroluminescent displays can be increased.

La présente invention concerne un affichage électroluminescent multiplexé à multiplexage matriciel, à courant alternatif, comprenant un réseau de pixels électroluminescents à commutation capacitive, adressés en matrice, chacun desdits pixels comprenant un pixel électroluminescent et un élément de circuit connecté électriquement en série au pixel électroluminescent. L'élément de circuit peut être commuté entre un état capacitif électriquement isolant et un état électriquement conducteur selon la tension appliquée au pixel électroluminescent à commutation capacitive. L'affichage électroluminescent à multiplexage matriciel avec dispositif de commutation basse capacitance en série avec les pixels électroluminescents permet de réduire les courants de déplacement de colonne et donc la consommation d'énergie. Il est également possible de réduire les temps de rafraîchissement, ce qui permet d'accroître la taille et la résolution d'écrans électroluminescents à matrice passive.
