PROBLEM TO BE SOLVED: To provide a method for driving a video electro-optic display.SOLUTION: Video displays using relatively low frame rates of 10 to 20 frames per second but having acceptable video quality are described. The displays may use bistable media, and may be driven such that the medium, when driven, changes its optical properties continuously during the driving of each frame. The displays may use an electro-optic medium such that the frame period is from 50 to 200 per cent of the switching time of the electro-optic medium at the driving voltage used. 【課題】ビデオ電気光学ディスプレイを駆動する方法の提供。【解決手段】毎秒１０フレームから毎秒２０フレームの比較的低いフレームレートを用いるが、許容し得るビデオの質を有するビデオディスプレイが説明される。ディスプレイは、双安定性媒体を用い得、駆動されるとき、各フレームの駆動中に媒体が媒体の光学特性を連続的に変化させるように駆動され得る。ディスプレイは、用いられる駆動電圧においてフレーム期間が電気光学媒体の切り換え時間の５０パーセントから２００パーセントであるような電気光学媒体を用い得る。【選択図】図２
