Title (EN) LIQUID CRYSTAL DISPLAY DEVICE AND DRIVE METHOD THEREFOR
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES ET SON PROCÉDÉ DE PILOTAGE
(ZH) 液晶显示器件及其驱动方法
Abstract:
(EN) A drive method for a liquid crystal display device, comprising: S110, displaying each picture by means of two image frames (frame_N-1, frame_N-2) in sequence, two adjacent sub-pixels on each image frame being different in driving voltage, and the first image frame (frame_N-1) and the second image frame (frame_N-2) of each sub-pixel being different in driving voltage; S120, determining a backlight brightness regulating signal of each backlight partition (M) according to driving signals of a first image frame area and a second image frame area corresponding to the backlight partition, as well as driving signals of first image frame areas and second image frame areas corresponding to backlight partitions (M) adjacent to the backlight partition (M) in first, second, third, and fourth directions, the backlight brightness regulating signals being grouped signals (AM_P1, AM_P2) and the quantity of groups of the signals being equal to the quantity of varieties of color sub-pixels (R, G, B sub-pixels); and S130, conducting independent brightness regulation on backlight sources of the color sub-pixels (R, G, B sub-pixels) within corresponding backlight partitions (M) of various image frames of the next picture according to the backlight brightness regulating signal of each backlight partition (M).
(FR) La présente invention concerne un procédé de pilotage pour dispositif d'affichage à cristaux liquides. Ledit procédé comprend les étapes consistant à : S110, afficher chaque image au moyen de deux trames d'image (trame_N-1, trame_N-2) dans cet ordre, deux sous-pixels adjacents sur chaque trame d'image ayant des tensions de pilotage différentes, la première trame d'image (trame_N-1) et la seconde trame d'image (trame_N-2) de chaque sous-pixel ayant des tensions de pilotage différentes; S120, déterminer un signal de régulation de luminosité de rétroéclairage de chaque partition de rétroéclairage (M) en fonction de signaux de pilotage d'une première zone de trame d'image et d'une seconde zone de trame d'image correspondant à la partition de rétroéclairage et de signaux de pilotage des premières zones de trames d'image et des secondes zones de trames d'image correspondant à des partitions de rétroéclairage (M) adjacentes à la partition de rétroéclairage (M) dans des première, deuxième, troisième et quatrième directions, les signaux de régulation de luminosité de rétroéclairage étant des signaux groupés (AM _ P1, AM_P2) et la quantité de groupes des signaux étant égale à la quantité de variétés de sous-pixels de couleurs (sous-pixels R, V, B); et S130, réaliser une régulation de luminosité indépendante sur des sources de rétroéclairage des sous-pixels de couleurs (sous-pixels R, V, B) dans des partitions de rétroéclairage correspondantes (M) de diverses trames d'image de la prochaine image en fonction du signal de régulation de luminosité de rétroéclairage de chaque partition de rétroéclairage (M).
(ZH) 一种液晶显示器件的驱动方法,包括:S110,将每一幅画面使用两帧图像(frame_N-1,frame_N-12)依序显示;每一帧图像上的相邻两个子像素的驱动电压为一高一低,且每一个子像素在第一帧图像(frame_N-1)中的驱动电压和在第二帧图像(frame_N-2)中的驱动电压为一高一低;S120,根据每个背光分区(M)对应的第一帧图像区域和第二帧图像区域及背光分区(M)第一方向、第二方向、第三方向、第四方向相邻的背光分区(M)对应的第一帧图像区域和第二帧图像区域的驱动电压确定每个背光分区(M)的背光亮度调节信号;背光亮度调节信号为成组信号(A M_P1,A M_P2)且组数与颜色子像素(R、G、B子像素)的种类数相同;以及S130,根据每个背光分区(M)的背光亮度调节信号对下一幅画面的各帧图像中的相应背光分区(M)内的各种颜色子像素(R、G、B子像素)的背光源进行独立的亮度调节。
