Abstract:
(EN) A liquid crystal pixel circuit, a driving method therefor and a liquid crystal display panel. The liquid crystal pixel circuit comprising a plurality of pixel units (100) arranged in a matrix, and every pixel unit (100) is coupled to a corresponding data line (D(n)) and a corresponding gate line (G(n), G(n+1)). Every pixel unit (100) comprises a first switch assembly (310), a second switch assembly (320) and a charge sharing switch (330), which are distributed in a main pixel area and a sub-pixel area (110, 120) and electrically coupled to the data line (D(n)) and the grid line (G(n), G(n+1)); wherein the control terminal (313) of the first switch assembly (310) and the control terminal (323) of the second switch assembly (320) in the (n+1)th row of pixel units (100) and the control terminal (333) of the charge sharing switch (330) in the nth row of pixel units (100) are electrically coupled to the (n+1)th gate line (G(n+1)). The driving method is used for driving a liquid crystal pixel circuit.
(FR) La présente invention concerne un circuit de pixel à cristaux liquides et son procédé de commande, et un panneau d’affichage à cristaux liquides. Le circuit de pixel à cristaux liquides comprend une pluralité d’unités de pixels (100) agencées dans une matrice, et chaque unité de pixel (100) est couplée à une ligne de données correspondante (D(n)) et à une ligne de grille correspondante (G(n), G(n+1)). Chaque unité de pixel (100) comprend un premier ensemble de commutateur (310), un deuxième ensemble de commutateur (320) et un commutateur de partage de charge (330), qui sont répartis dans une zone de pixel principal et une zone de sous-pixel (110, 120) et électriquement couplés à la ligne de données (D(n)) et à la ligne de grille (G(n), G(n+1)) ; la borne de commande (313) du premier ensemble de commutateur (310) et la borne de commande (323) du deuxième ensemble de commutateur (320) dans la (n+1)ième ligne d’unités de pixels (100) et la borne de commande (333) du commutateur de partage de charge (330) dans la nième rangée d’unités de pixel (100) étant électriquement couplées à la (n+1)ième ligne de grille (G(n+1)). Le procédé de commande est utilisé pour commander un circuit de pixel à cristaux liquides.
(ZH) 一种液晶像素电路及其驱动方法与液晶显示面板,液晶像素电路包括多个以矩阵方式排列的像素单元(100),每一像素单元(100)耦接相应的数据线(D(n))与栅极线(G(n), G(n+1));每一像素单元(100)包括分布在主、子像素区域(110, 120),并与数据线(D(n))与栅极线(G(n), G(n+1))电性耦接的第一开关组件(310)、第二开关组件(320)与电荷分享开关(330);其中,第n+1行像素单元(100)的第一开关组件(310)的控制端(313)、第二开关组件(320)的控制端(323)与第n行像素单元(100)的电荷分享开关(330)的控制端(333)电性耦接至第n+1条栅极线(G(n+1));驱动方法用以驱动液晶像素电路。
