发明名称 Electrophoresis display device and electronic equipments using the same
摘要 An object of the present invention is to provide an active matrix type electrophoresis display device whose number of the times of writings is further smaller. In an electrophoresis display device which performs the display of picture using a n-bit digital picture signal, the respective pixels are divided into a plurality of sub-pixels, the respective sub-pixels have a 1-bit memory circuit. Since an electrophoresis element is stable in once written state, upon the display of static picture, the picture is retained by the digital picture signal retained in a memory circuit, therefore, a periodic refresh operation which is conventionally considered to be required are capable of being omitted.
