Abstract
A method of 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 grouping gate lines and simultaneously driving those gate lines as a gate block, a frame update can be completed much faster and, as a consequence, the overall drive frequency at the propulsion electrodes can be increased substantially. The faster drive frequency improves the performance of electrowetting devices, especially when used with aqueous droplets having a high ionic strength.
