Abstract
An active matrix electrowetting on dielectric (AM-EWOD) device which includes a plurality of array elements configured to manipulate one or more droplets of fluid on an array, each of the array elements including a corresponding array element circuit. Each array element circuit includes a top substrate electrode and a drive electrode between which the one or more droplets may be positioned; circuitry configured to write data to the corresponding array element by selectively applying to the drive electrode either: (i) a time-varying voltage waveform Vof amplitude Vand period t; or (ii) a time-varying voltage waveform V, the logical inverse of V, and applying to the top substrate electrode the time-varying voltage waveform V+V, where Vrepresents an offset voltage signal which may have AC and/or DC components and may equal zero.
