Abstract: In this paper, a novel method of creating monodisperse microdroplets for electrophoretic display microcapsules application is introduced. The microcapsules fabricated by common agitation are lack of uniformity, which result in difficulty in driving waveform design. In this report, we fabricated the narrow distributed microdroplets of EPD materials using two types of microchannel with the outer phase of 15% gelatin and Arabic gum solution and the inner phase of tetrachloroethylene. Controlling the flow rate ratio of the inner to outer phase at 2:1 (small channel) and 10:6 (big channel), we could obtain monodisperse microdroplets with diameter of 47 ?m and 315 ?m, respectively. At the same, the size of the microdroplet could be precisely controlled by the fluidic flow rates. The size distribution of the microdroplets fabricated by microfluidic channels was (450.28) m which was highly improved comparing to the droplets created by agitation with the size of （5218.81) m. This implies that the microfluidics is a reliable technology which would be a feasible way to improve the quality and performance of the electrophoretic displays.
