Electrowetting has shown its power in manipulating microfluidics. Of particular interest is a bistable electrowetting system, which enables versatile low power consumption applications. A combined design of electrode and wettability patterning, which includes a unique three‐electrode structure and wettability barrier, was proposed and introduced into as a new electrofluidic display (EFD) architecture. This architecture should be manufacturable in a fairly straightforward way within LCD cell‐making technology. For this architecture, an electrohydrodynamic two phase flow simulation was carried out using the COMSOL Multiphysics simulation software. The results show that this new EFD architecture could achieve a bistable display property. Compared with conventional EFD, the electro‐optical performance (the aspect ratio and response time) of this design has also been greatly improved.
