Abstract
Description
表示装置は、第NMUXが第1MUX、第2MUX及び第3MUXを含み、第1フレーム中の第1H期間において、第1MUX、第2MUX及び第3MUXのターンオンが第1パターンを有し、第1フレーム中の第1パターンは第3MUXのターンオン期間が最も長く、第3MUXのターンオン期間はスキャン信号のサンプリング期間とオーバーラップするが、第3MUXのターンオン開始時点はスキャン信号のサンプリング期間の開始時点よりも先行することができる。
表示装置1は様々な形態で実現できる。例えば、表示装置1は長方形の板状に実現できる。しかし、本実施形態は、これに限定されず、表示装置1は、正方形、円形、楕円形、多角形などの様々な形状を有することができ、角部の一部が曲面からなるか或いは少なくとも一領域の厚さが変わる形状を有することができる。また、表示装置1は、全体又は一部が可撓性(flexibility)を有することができる。
ここで、第NMUXを基準として説明すると、以下の通りである。Nが3であると仮定すると、第NMUXは、第1MUX、第2MUX及び第3MUXを含む。第1フレーム中の第1H期間では、第1パターンを有し、第1パターンは、第3MUXのターンオン期間が第1MUX及び第2MUXのターンオン期間と異なる。例えば、第3MUXのターンオン期間が相対的にさらに長いことができる。第3MUXのターンオン開始時点がサンプリング信号の開始時点よりも先行しなければならないのは、上述したのと同じである。すなわち、3つのMUXのうちいずれか一つのMUXのターンオン期間が最も長いことができ、最も長いMUXのターンオン期間が最も後行することができる。また、最も長いターンオン期間を有するMUXのターンオン期間はサンプリング期間とオーバーラップすることができ、このとき、MUXのターンオン期間の開始時点はサンプリング期間の開始時点よりも先行することができる。
