Inhibiting Oil Splitting and Backflow in Electrowetting Displays by Designing a Power Function Driving Waveform [PDF]
Electronics (Switzerland), 2022 Electrowetting display (EWD) is one of the latest and most promising reflective displays. However, some defects are easily caused in a driving process. For example, the aperture ratio of pixels can be reduced due to oil splitting, and the grayscale cannot be stabilized due to charge trapping. These defects can be effectively solved by designing driving
