コレステリック液晶表示装置は、上述のような現象を利用して画像情報の表示を行う(例えば、特許文献1参照。)。
1.全画面表示をした場合の表示パネルの面内ムラ
図5は、従来技術の課題(その1)を説明するための図である。
また、通常、コモン側の走査線で選択電圧を印加するが(図5の(A)参照)、走査の序盤に走査線が選択した箇所(ラインA)と、終盤に走査線が選択した箇所(ラインD)では若干の色の差(画面内のムラ)ができてしまう(図5の(B)参照)。
2.部分書き換え表示をした場合の色差
図6は、従来技術の課題(その2)を説明するための図である。
すなわち、本発明の一態様によれば、本発明の不揮発性液晶表示装置は、走査信号線群と前記走査線信号群に交差するデータ信号線群と前記信号線群が交差する位置に配された複数の画素回路とを含み、液晶層として不揮発性液晶化合物を含有する液晶表示パネルと、前記走査信号線群を順に駆動する走査信号線駆動手段と、前記走査信号線駆動手段に選択電圧と非選択電圧を供給する制御手段を備える。そして、前記制御手段が、前記走査信号線群を構成する全ての走査信号線のそれぞれに対して、前記選択電圧を供給する前および後の所定期間に前記非選択電圧を供給することを特徴とする。
また、本発明の一態様によれば、本発明の表示方法は、走査信号線群と、前記走査線信号群に交差するデータ信号線群と、前記信号線群が交差する位置に配された複数の画素回路とを含み、液晶層として不揮発性液晶化合物を含有する液晶表示パネルと、前記走査信号線群を順に駆動する走査信号線駆動手段と、前記走査信号線駆動手段に選択電圧と非選択電圧を供給する制御手段とを備えた不揮発性液晶表示装置の表示方法であって、前記制御手段が、前記走査信号線群を構成する全ての走査信号線のそれぞれに対して、前記選択電圧を供給する前および後の所定期間に前記非選択電圧を供給することを特徴とする。
図1は、本発明を適用した第1の実施の形態を説明するための図である。
本発明が適用される不揮発性液晶表示装置は、走査信号線群と前記走査線信号群に交差するデータ信号線群とこれらの信号線群が交差する位置に配された複数の画素回路とを含み、液晶層としてコレステリック液晶等の不揮発性液晶化合物を含有する液晶表示パネルを有する。そして、前記走査信号線群が順に駆動されることにより、前記液晶表示パネルが画像を表示することができる。
