Abstract

　光検出素子を画素内に有し、表示装置の動作中に光センサ信号を自動的に補正することが可能な表示装置を提供する。センサロウドライバ（５）は、画素領域（１）の光センサへ第１のパターンのセンサ駆動信号を供給することにより、光センサの受光量に応じた光センサ信号を信号処理回路（８）へ出力する第１の動作モードと、第２のパターンのセンサ駆動信号を供給することにより、光センサが黒レベルを検出した場合に相当する補正用の第１の光センサ信号レベルを取得する第２の動作モードと、第３のパターンのセンサ駆動信号を供給することにより、光センサが白レベルを検出した場合に相当する補正用の第２の光センサ信号レベルを取得する第３の動作モードとを有する。信号処理回路（８）は、前記第１および第２の光センサ信号レベルを用いて、第１の動作モード時の光センサ信号を補正する。
