    • In an image display device including: an electrophoretic display element having a memory property and a display/update controlling unit which outputs the first control signal and the data signal to the data line driving circuit, and the second control signal to the scanning line driving circuit, based on given image data, during the image updating period of time, and cuts off power supply to the data line driving circuit and the scanning line driving circuit, during an image holding period of time, the display/update controlling unit, during the image updating period of time, inputs sequentially a plurality of pieces of compressed image block data having a data configuration which one screen of the image data is divided into a plurality of blocks, and compressed for each block, expands the compressed image block data of a preceding screen and the compressed image block data of a corresponding updating screen sequentially inputted, and outputs the data signal for screen update to the data line driving circuit, based on the expanded image block data of the preceding screen and the expanded image block data of the corresponding updating screen.
    • 一种图像显示装置,包括:具有存储特性的电泳显示元件和显示/更新控制单元,其将第一控制信号和数据信号输出到数据线驱动电路,第二控制信号输出到扫描线驱动电路 基于给定的图像数据,在图像更新期间,在图像保持期间,在数据线驱动电路和扫描线驱动电路的切断电源期间,在显示/更新控制单元期间, 图像更新时间段,顺序地输入具有数据配置的多个压缩图像块数据,该图像数据的一个屏幕被划分为多个块,并且对于每个块进行压缩,将压缩的图像块数据扩展 顺序地输入相应的更新画面的压缩图像块数据,并输出用于屏幕更新的数据信号到da ta线驱动电路,基于前一屏幕的扩展图像块数据和相应更新屏幕的扩展图像块数据。
