ホスト制御部30は、表示データに更新があったときに、1画面分の更新表示データを表示駆動部(20)へ転送する。ホスト制御部30は、画面更新検知部31と、ホスト側記憶部32と、ホスト側TG(タイミングジェネレータ)33とを備えている。ホスト制御部30は、例えば基板上に形成された制御回路で構成されている。具体的には、ホスト制御部30は、例えばCPU(Central Processing Unit)であってもよく、GPU(Graphics Processing Unite)であってもよく、CPUおよびGPUを含む装置であってもよい。
表示駆動部20は、ホスト制御部30からの指示に基づいて表示部10を駆動する。表示駆動部20は、例えば、表示部10のガラス基板にCOG(Chip on Glass)実装された、いわゆるCOGドライバであってもよく、表示部10のフレキシブル基板にCOF(Chip on Flexible)実装された、いわゆるCOFドライバであってもよい。また、表示駆動部20は、表示部10のプラスチック基板にCOP(Chip on Plastic)実装された、いわゆるCOPドライバであってもよい。表示駆動部20は、表示側記憶部21(メモリ)と、表示側TG22(発光制御部)と、ソースドライバ23とを備える。
図2は、表示装置1において動画を表示するときのタイミングチャートである。図2は、いずれも静止画である画像A、画像B、画像Cおよび画像Dが、この順番で表示部10に表示される例を示す。図2に示す例では、画像Aについては、6フレームにかけて表示部10に表示される例を示す。

バイアス決定部34によるバイアス電圧の大きさの決定処理は、上述の決定処理の内容に限られず、様々な変形例が考えられる。
表示装置1、1A、1Cの制御ブロック(特に、ホスト制御部30および表示駆動部20、20A)は、集積回路(ICチップ)等に形成された論理回路(ハードウェア)によって実現してもよいし、ソフトウェアによって実現してもよい。
本発明の態様1に係る表示装置1、1A、1Bは、自発光素子が配列された画面を備えた表示部と、前記画面に、表示データに基づく表示を行わせるように、前記表示部を駆動する表示駆動部と、前記表示データに更新があったとき、1画面分の更新表示データを前記表示駆動部へ転送するホスト制御部と、を備え、前記表示駆動部は、前記自発光素子を発光させる発光制御部と、1画面分の前記更新表示データを記憶するメモリとを備え、前記表示駆動部によって、前記更新表示データに基づいた前記表示部の駆動を終了する駆動終了時刻から所定の時間経過後に、前記メモリに記憶された前記更新表示データを読み出し、読み出した更新表示データを用いて、前記画面を駆動し、前記ホスト制御部から前記表示駆動部への前記更新表示データの更新無しのタイミングで、前記自発光素子を1回以上駆動させる。
本発明は上述した各実施形態に限定されるものではなく、請求項に示した範囲で種々の変更が可能であり、異なる実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。さらに、各実施形態にそれぞれ開示された技術的手段を組み合わせることにより、新しい技術的特徴を形成することができる。
