Aperture Ratio Improvement by Optimizing the Voltage Slope and Reverse Pulse in the Driving Waveform for Electrowetting Displays. [PDF]

Micromachines (Basel), 2019
Electrowetting display (EWD) performance is severely affected by ink distribution and charge trapping in pixel cells. Therefore, a multi structural driving waveform is proposed for improving the aperture ratio of EWDs.

Common mode output waveforms reduction for Matrix Converters drives [PDF]

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents an alternative Space Vector Modulation (SVM) implemented in Matrix Converters (MC) which improves and reduces the Common Mode (CM) voltage and current output waveforms. The strategy is based on replacing the MC zero vectors for the rotating ones, which reduces the CM voltage derivative and therefore the leakage CM current.

The design of an inkjet drive waveform using machine learning

Scientific Reports, 2022
AbstractA drive waveform, which needs to be optimized with ink’s fluid properties, is critical to reliable inkjet printing. A generally adopted rule of thumb for its design is mostly dependent on time-consuming and repetitive manual manipulation of its parameters.
