Abstract
(EN) In order to reduce crosstalk and achieve favorable image display quality when displaying a three-dimensional image on a plasma display panel, disclosed is a method―that is for driving a plasma display device and that displays an image on a plasma display panel by alternately repeating a right-eye field that displays a right-eye image signal and a left-eye field that displays a left-eye image signal―wherein, in a first field and a second field that are chronologically in succession, in discharge cells of which the gradient value displayed in the second field, which arises later in time, is less than or equal to a preset comparison value, when displaying a gradient that is greater than or equal to a predetermined threshold in the first field, which arises earlier in time, image data are set that forbid a write operation at the final subfield to arise of the first field.
(FR) Afin de réduire la diaphonie et d'obtenir une meilleure qualité d'affichage d'image lors de l'affichage d'une image tridimensionnelle sur un panneau d'affichage plasma, l'invention propose un procédé d'actionnement de dispositif d'affichage plasma, qui consiste à afficher une image sur un panneau d'affichage plasma en répétant de manière alternative un champ d'œil droit qui affiche un signal d'image d'œil droit et un champ d'œil gauche qui affiche un signal d'image d'œil gauche. Selon ce procédé, dans un premier champ et un second champ qui se suivent chronologiquement et dans les cellules de décharge desquels la valeur de gradient affichée dans le second champ, qui survient plus tard, est inférieure ou égale à une valeur de comparaison prédéterminée, lorsque l'on affiche un gradient qui est supérieur ou égal à un seuil prédéterminé dans le premier champ, qui survient plus tôt, des données d'image sont établies de manière à interdire une opération d'écriture au sous-champ final pour la venue du premier champ.
