Description
また、前記アナログ処理部は、前記入力データのうち、前記デジタル処理部により処理される上位ビットをマスクして下位ビットのみをアナログ変換する。
また、前記入力データは、上位ビットと下位ビットで別々に転送され、上位ビットの転送時に前記デジタル処理部により上位ビットのみが処理され、下位ビットの転送時に前記アナログ処理部により下位ビットのみが処理される。
さらに、デジタル画素およびアナログ画素は、それぞれ列方向に並んで配置され、デジタル画素の列に沿って前記デジタルデータラインが配置され、アナログ画素の列に沿って前記アナログデータラインが配置される。
また、下位4ビットのアナログ書き込みは、制御回路16が映像変化を検出しなければ、通常のリフレッシュレートより低く設定してもよい。通常60Hzであれば30Hzに周波数を低く設定することでさらに低消費電力化することができる。
