Abstract
(EN)
A display driving method and a display driving device for driving a stereoscopic display device are provided. The display driving method comprises: respectively calculating color component of each sub-pixel in a plurality of the first pixel units and color component of each sub-pixel in a plurality of the second pixel units; and determining a sampling region of each sub-pixel, and determining a display brightness of the sub-pixel in accordance with the color components of sub-pixels, which is the same color as the sub-pixel and in pixel units covered by the sampling region of the sub-pixel wherein the sampling region is a rhombic sampling region, and four vertexes of the rhombic sampling region are respectively midpoints of four lines in row and column directions connecting four central points of four sub-pixels, which are the same type as the sub-pixel, adjacent to the sub-pixel, in two columns adjacent to the sub-pixel.

L'invention concerne un procédé de commande d'affichage et un appareil de commande d'affichage utilisant ledit procédé de commande d'affichage pour commander un appareil d'affichage 3D, ledit procédé de commande d'affichage consistant à : calculer respectivement la composante de couleur des sous-pixels dans une pluralité de premières unités de pixels et la composante de couleur des sous-pixels dans une pluralité de secondes unités de pixels ; déterminer une zone d'échantillonnage de chaque sous-pixel et, d'après la composante de couleur identique à la couleur dudit sous-pixel dans les unités de pixels couvertes par la zone d'échantillonnage correspondant audit sous-pixel, déterminer la luminance dudit sous-pixel, la zone d'échantillonnage étant une zone d'échantillonnage rhombique, et les quatre points de la zone d'échantillonnage rhombique étant les milieux des lignes de connexion centrales de quatre sous-pixels identiques à proximité dudit sous-pixel et positionnés dans les colonnes adjacentes audit sous-pixel.
