Description
前記所定の電圧は、前記第2データブロックにデータ信号を印加するとき前記第2データブロックの1番目のデータラインに供給されるデータ信号と同一である
また、両方向駆動の際にも駆動方向によって現在画素ブロックと最も隣接した次画素ブロックのデータラインがプリチャージされるようにすることで各画素ブロックのエッジ部に位置する画素電極の電圧変動を最小化することができるようになる。
従って、画素ブロック間の信号干渉によるブロック境界線不良を防止することができるようになる。
以下、本発明による液晶パネルのデータ駆動方法及び装置を実施するための最良の形態の具体例を、図面を参照しながらより詳細に説明する。
12、42 画素電極
20、40 画像表示部
22、28 NAND
24、26、29 インバータ
70 プリチャージ制御部
80 プリチャージ部
SRm、SRm+1 シフトレジスタ
SBm、SBm+1 サンプリングスイッチ部
PBm、PBm+1 画素ブロック
DS 方向選択信号
SWb 逆方向サンプリングスイッチ
SWf 順方向サンプリングスイッチ
