Abstract
【解決手段】複数の画素を含む液晶表示装置の駆動装置であって、第1及び第2基準階調電圧を生成する階調電圧生成部と、共通電圧を生成する共通電圧生成部と、前記第1及び第2基準階調電圧に基づいてデータ電圧を生成して前記画素に印加するデータ駆動部とを含み、前記階調電圧生成部は前記液晶表示装置の種類によって前記第1基準階調電圧の大きさを変化させる抵抗変換部を含む。
【選択図】図6
Description
しかし、現在使用されている階調電圧生成部はツイステッドネマチック方式の液晶分子を基準として階調電圧を生成するので、他の方式の液晶表示装置には使用できない。
以下、本発明の実施形態による液晶表示装置の駆動装置について図面を参照して詳細に説明する。
以下では特に言及しない限り、例えば図3、図4におけるように、主表示板部と副表示板部に共通する構成について説明する場合は、表示板部の図面符号として‘300’、ゲート駆動部の図面符号として‘400’、データ駆動部の図面符号として‘500’を各々使用する。
図4に示すように、液晶表示装置の画素(PX)は、下部表示板100、上部表示板200に各々搭載された画素電極191及び共通電極270と、その間の前記液晶層3(図示せず)を含み、画素電極191は行列状に配列されていて、薄膜トランジスタ(TFT)Qなどスイッチング素子に連結されて1行ずつ順次にデータ電圧Djの印加を受ける。共通電極270は表示板の全面にわたって形成されており、共通電圧の印加を受ける。画素電極191と共通電極270及びその間の前記液晶層3(図示せず)は回路的に見れば液晶キャパシタClcをなし、液晶キャパシタClcはこれに連結されたスイッチング素子Qと共に、画素PXを構成する。
再び図1を参照すると、表示信号線G1〜Gn、D1〜Dmは、表示板部300の周辺領域320M、又は320Sにおいて、各々FPC650、680が付着される箇所でそのピッチが変更されて、各々の信号線にパッド(図示せず)が形成され、表示板部300M、300SとFPC650、680は、これらパッドにおいて、電気的接続のための異方性導電膜(図示せず)を介して付着されている。
また、信号制御部600はゲート駆動部400及びデータ駆動部500を含むなどの機能ブロックの動作を制御する。
統合チップ700は、図2に示すように、前述した階調電圧生成部800、ゲート駆動部400M、400S、データ駆動部501、502及び信号制御部600以外に、オシレータ610、複数のメモリ621、622、623、624及び共通電圧生成部631、632(なお、後述の図3では、共通電圧生成部として、図面符号‘750’を使用する。)などを含む。オシレータ610は各種の駆動信号の動作に必要な基準クロックを提供し、メモリ621〜624は外部からの映像信号を記憶し、共通電圧生成部631、632は共通電圧Vcomを生成して主表示板部300M及び副表示板部300Sに各々供給し、その他の駆動回路の動作に必要な電源をさらに生成する。
図6(A)(B)いずれにしても、スイッチング素子SWの導通・遮断により、図7に示したグラフのように、階調による電圧の推移形状を変えることができる。
