Impedance analysis of oil conductivity and pixel non-uniformity in electrowetting displays

Results in Physics, 2020
The electrical conductivity of the oil film is a key property of electrowetting displays (EWD) and its evolution probably correlates to the device lifetime. In this report, we fabricate an EWD device and measure its electrical impedance spectrum.
