Title
(EN) LIQUID CRYSTAL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES

Abstract
(EN)
A liquid crystal display device, comprising: a plurality of sub-pixels (11, 12, 13) arranged in an array, wherein each of the sub-pixels (11, 12, 13) is an eight-domain structure; the polarities of data signals of two adjacent columns of sub-pixels (11, 12, 13) are opposite in a frame of picture, and the polarities of data signals of the same sub-pixel (11, 12, 13) are opposite in two adjacent frames of picture; and each two adjacent sub-pixels (11, 12, 13) in a row direction form a sub-pixel group, all of the sub-pixels (11, 12, 13) in one sub-pixel group (40) of two adjacent sub-pixel groups (40) display the brightness of a first display grayscale corresponding thereto, and the sub-pixels (11, 12, 13) in the other sub-pixel group (40) of the two adjacent sub-pixel groups display the brightness of a second display grayscale corresponding thereto. By carrying out color cast compensation on the data signals of the sub-pixels (11, 12, 13) in an eight-domain structure, a chrominance angle of the visibility of a liquid crystal display device can be improved, and the watching experience of the liquid crystal display device can be improved.

Selon l'invention, un dispositif d'affichage à cristaux liquides, comprend : une pluralité de sous-pixels (11, 12, 13) disposés dans un réseau, chacun des sous-pixels (11, 12, 13) consistant en une structure à huit domaines ; les polarités de signaux de données de deux colonnes adjacentes de sous-pixels (11, 12, 13) sont opposées dans une trame d'image, et les polarités des signaux de données du même sous-pixel (11, 12, 13) sont opposées dans deux trames adjacentes d'image ; et chacun de deux sous-pixels adjacents (11, 12, 13) dans une direction de rangée forment un groupe de sous-pixels, tous les sous-pixels (11, 12, 13) dans un groupe de sous-pixels (40) de deux groupes de sous-pixels adjacents (40) affichent la luminosité d'une première échelle de gris d'affichage correspondant à cette dernière, et les sous-pixels (11, 12, 13) dans l'autre sous-groupe de sous-pixels (40) des deux groupes de sous-pixels adjacents affichent la luminosité d'une seconde échelle de gris d'affichage correspondant à cette dernière. Par réalisation d'une compensation de diffusion de couleur sur les signaux de données des sous-pixels (11, 12, 13) dans une structure à huit domaines, un angle de chrominance de la visibilité d'un dispositif d'affichage à cristaux liquides peut être amélioré, et l'expérience de visualisation du dispositif d'affichage à cristaux liquides peut être améliorée.
