Title (EN) LIQUID CRYSTAL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(JA) 液晶表示装置
Abstract:
(EN) An active matrix substrate for a liquid crystal display device comprises: a plurality of pixels; a plurality of source lines; a plurality of gate lines; and a plurality of drive circuits that scan the gate lines. A counter substrate for the liquid crystal display device comprises color filters of a plurality of colors. Two source lines (SLn, SLn+1/SLn+2, SLn+3) that have applied thereto data voltage having mutually opposite polarity are provided in every three columns of pixels and the data voltage polarity is inverted at each frame. A first gate line (GLn–1), a second gate line (GLn), and a third gate line (GLn+1) are provided for every two rows of pixels. The second gate line (GLn) has one pixel (G) connected thereto and other colored pixels (R, B) sandwiching the pixel (G) are connected to either the first gate line (GLn–1) or the third gate line (GLn+1). Data voltage of opposite polarity is applied to the other pixels (R) (B). The second gate line (GLn) is scanned first out of the first gate line (GLn–1), the second gate line (GLn), and the third gate line (GLn+1).
(FR) Selon l’invention, un substrat de matrice active pour un dispositif d'affichage à cristaux liquides comprend : une pluralité de pixels ; une pluralité de lignes de source ; une pluralité de lignes de grille ; et une pluralité de circuits de commande qui balaient les lignes de grille. Un contre-substrat pour le dispositif d'affichage à cristaux liquides comprend des filtres colorés d'une pluralité de couleurs. Deux lignes de source (SLn, SLn +1/SLn +2, SLn +3) auxquelles est appliquée une tension de données ayant une polarité mutuellement opposée sont prévues dans une colonne de pixels sur trois et la polarité de tension de données est inversée dans chaque trame. Une première ligne de grille (GLn-1), une deuxième ligne de grille (GLn) et une troisième ligne de grille (GLn+1) sont prévues pour une rangée de pixels sur deux. Un pixel (G) est connecté à la deuxième ligne de grille (GLn) tandis que les autres pixels colorés (R, B) prenant en sandwich le pixel (G) sont connectés à la première ligne de grille (GLn-1) ou à la troisième ligne de grille (GLn+1). Une tension de données de polarité opposée est appliquée aux autres pixels (R). La deuxième ligne de grille (GLn) est balayée en première parmi la première ligne de grille (GLn-1), la deuxième ligne de grille (GLn) et la troisième ligne de grille (GLn+1).
(JA) 液晶表示装置のアクティブマトリクス基板は、複数の画素、複数のソース線、複数のゲート線、ゲート線を走査する複数の駆動回路を備える。液晶表示装置の対向基板は複数の色のカラーフィルタを備える。3列の画素ごとに、互いに逆極性のデータ電圧が印加される2本のソース線(SLn,SLn+1/SLn+2,SLn+3)が設けられ、データ電圧の極性はフレーム毎に反転される。2行の画素毎に、第1のゲート線(GLn-1)、第2のゲート線(GLn)、第3のゲート線(GLn+1)が設けられる。第2のゲート線(GLn)は一の画素(G)が接続され、画素(G)を挟む他の色の画素(R、B)は、第1のゲート線(GLn-1)又は第3のゲート線(GLn+1)と接続される。他の画素(R)(B)は逆極性のデータ電圧が印加される。第1のゲート線(GLn-1)、第2のゲート線(GLn)、第3のゲート線(GLn+1)のうち第2のゲート線(GLn)が最初に走査される。
