In this design,STM32 series microprocessor is taken as the controller,uCGUI for graphical interface design and cyclic shift algorithm for making the black⁃and⁃white image meet the TFT⁃EFD(Electro⁃ Fluidic Display)data format to realize static EFD image data transmission. It can transmit various static EFD images according to the practical requirement. If needs later on,it can be upgraded to transmit data flow to support the dynamic display.%在此计以STM32系列处理器作为控制器，利用uCGUI进行图形界面设计，利用循环移位算法将黑白图像定制成符合TFT⁃EFD显示的数据格式，实现了静态EFD图像的数据传输，可以根据实际要求传输不同静态EFD图像，后期如果需要可以升级成传输数据流来支持动态显示。
