Patent

CA 2613672

A method of driving a liquid crystal device that comprises at least a pair of substrates and a liquid crystal material disposed between the pair of substrates. A voltage increase rate to be attained during the duration of a voltage pulse applied to the liquid crystal device is changed in order to continuously control the quantity of light transmitted by the liquid crystal device, whereby shades are displayed.

L'invention concerne un procédé de commande d'un dispositif d'affichage à cristaux liquides qui comprend au moins une paire substrats et un matériau de cristaux liquides disposé entre les deux substrats. Un taux d'augmentation de la tension devant être atteint pendant la durée de l'impulsion de tension appliquée au dispositif à cristaux liquides est modifiée afin de réguler de façon continue la quantité de lumière transmise par le dispositif à cristaux liquides, ce qui permet d'afficher les nuances.
