Abstract
【解決手段】 異なる最適駆動電圧の液晶をメインパネルとサブパネルで使い、表示したいパネルにはその最適駆動電圧を出力する。表示したくない側のパネルには、最適駆動電圧より高いか低い駆動電圧が印加されるため、全画面単一色の表示となり、表示したくないパネルの表示内容は認識できない。

Claims (5)
- 第一の表示パネルと、前記第一の表示パネルとは最適駆動電圧の異なる第二の表示パネルと、前記第一の表示パネルと前記第二の表示パネルに駆動信号を並列に供給するドライバICと、を備え、
前記ドライバICは、前記第一の表示パネルの最適駆動電圧を持つ第一の駆動信号と前記第二の表示パネルの最適駆動電圧を持つ第二の駆動信号とを切り替えて出力するとともに、前記第一の駆動信号を出力したとき、前記第二の表示パネルは全画面が単一色表示となることを特徴とする表示装置。 - 前記第二の表示パネルの最適駆動電圧は前記第一の表示パネルの最適駆動電圧よりも低く、かつ、前記第二の表示パネルの表示モードがノーマリ―ホワイト・モードであることを特徴とする請求項1に記載の表示装置。
- 前記第二の表示パネルの最適駆動電圧は前記第一の表示パネルの最適駆動電圧よりも高く、かつ、前記第二の表示パネルの表示モードがノーマリーブラック・モードであることを特徴とする請求項1に記載の表示装置。
- 前記第一の表示パネルと前記第二の表示パネルは異なる画素数であり、前記第一の駆動信号と前記第二の駆動信号は駆動デューティーと駆動バイアス比が異なることを特徴とする請求項1〜3のいずれか一項に記載の表示装置。
- 請求項1〜4のいずれか一項に記載の表示装置を表示画面として用いたことを特徴とする電子機器。
