Claims (1)
- 複数の画素がマトリックス状に配置された表示パネルと、外部から表示データを入力するコントロール回路と、前記表示データに応じた階調電圧を前記画素へ印加する信号線駆動回路と、前記階調電圧を印加すべき画素を選択する走査線駆動回路とを備えた表示装置において、
前記コントロール回路は、タイミング制御回路と、各々2走査線分の表示データを格納する2つのラインメモリA及びBと、2つの演算回路A及びBと、前記2つの演算回路A及びBから出力される表示データの何れかを選択する選択回路を有し、
前記タイミング制御回路の制御信号出力により前記2つのラインメモリA及びBに格納された1水平走査期間前の表示データと現水平走査期間の表示データを2倍の速度で読み出して前記2つの演算回路A及びBで1水平走査期間を前半と後半の期間の表示データを生成し、
前記2つの演算回路A及びBは、前記前半の期間の表示データを1水平走査期間前の表示データと現水平走査期間の表示データと、前記信号線駆動回路の内部負荷及び表示パネルの書き込みを行う画素までの負荷との3つの値によって決定し、前記後半の期間の表示データを現水平走査期間の表示データとし、
前記信号線駆動回路は、1水平走査期間内における前記後半の期間で前記表示データに応じた階調電圧を前記各画素へ印加する前に、前記1水平走査期間前の表示データと現水平走査期間の表示データと、前記信号線駆動回路の内部負荷及び表示パネルの書込みを行う画素までの負荷との3つの値によって決定される前記表示データに対応する電圧を当該画素に印加するものであることを特徴とした表示装置。
