Abstract
Methods and systems for driving an active matrix electrowetting on dielectric device including thin-film-transistors to increase the switching frequency of the propulsion electrodes beyond what is typical for line-by-line active matrix driving. By using a latching circuit, it is possible to selectively switch specific propulsion (pixel) electrodes between an 'on' and an 'off' state, wherein a propulsion electrode in an “on” state can be driven by a time varying drive voltage on the top electrode that is a much higher frequency than is typically possible with amorphous silicon thin-film-transistor arrays. The faster drive frequency improves the performance of electrowetting devices, especially when used with aqueous droplets having a high ionic strength.
