    • A method of driving an electrophoretic display device displays an image during an image frame divided into a plurality of sub-frames. Sub-frame periods of the plurality of sub-frames are determined based on a predetermined resolution of the image. The plurality of sub-frames have sub-frame periods that differ from one another. A plurality of unit pixels are initialized by applying a common voltage to a common electrode and by applying a first voltage to a plurality of pixel electrodes. Each pixel electrode corresponds to a respective one of the plurality of unit pixels. Gray levels of the plurality of unit pixels are controlled by selectively applying one of the common voltage and a second voltage to each pixel electrode during each sub-frame.
    • 驱动电泳显示装置的方法在划分成多个子帧的图像帧期间显示图像。 基于图像的预定分辨率来确定多个子帧的子帧周期。 多个子帧具有彼此不同的子帧周期。 通过向公共电极施加公共电压并且通过向多个像素电极施加第一电压来初始化多个单位像素。 每个像素电极对应于多个单位像素中的相应一个。 通过在每个子帧期间选择性地将一个公共电压和第二电压施加到每个像素电极来控制多个单位像素的灰度级。
