Claims (1)
- 複数の画素セルが配列された表示装置を駆動する駆動回路において、該駆動回路は、
入力データと複数のガンマ補正電圧とに基づいて画素セルを選択する複数のデコーダと、
該複数のデコーダにそれぞれ接続され、該複数のデコーダの出力をそれぞれ増幅する複数の出力アンプと、
前記複数のデコーダに前記複数のガンマ補正電圧を供給する抵抗アレイと、
前記複数のデコーダと前記複数の出力アンプとの間に接続され、前記複数のガンマ補正電圧のうちいずれかの電圧を、前記複数のデコーダの出力に応じてそれぞれ選択する複数のスイッチ群とを含み、
前記複数のスイッチ群は、前記入力データの切り替わり時に、前記選択したガンマ補正電圧を前記出力アンプの入力に直接印加し、
さらに、該駆動回路は、
前記複数のデコーダに供給される前記複数のガンマ補正電圧をそれぞれ切り離す複数の第1のスイッチと、
前記複数のデコーダの出力と前記複数の出力アンプの入力とをそれぞれ切り離す複数の第2のスイッチとを含み、
前記複数の第1および第2のスイッチは、前記入力データの切り替わり時に接続を解除し、
さらに、該駆動回路は、
前記複数の出力アンプの出力と前記複数のデコーダの出力との間にそれぞれ接続され、前記複数の出力アンプの出力を前記複数のデコーダの出力にそれぞれ接続する複数の第3のスイッチを含み、
該第3のスイッチは、前記入力データの切り替わり時に前記複数の出力アンプの出力を充放電することを特徴とする駆動回路。
