Patent ID: 8339711

Claim:
An electrowetting on dielectric (EWOD) device, comprising: 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 driver circuit, wherein each array element driver circuit includes: a top substrate electrode and a first drive electrode between which the one or more droplets may be positioned, the top substrate electrode being formed on a top substrate, and the first drive electrode being formed on a lower substrate; and circuitry configured to selectively provide drive voltages to the first drive electrode to move the one or more droplets among the plurality of array elements, and wherein at least one of the plurality of array elements includes: a heater element also formed on the lower substrate and configured to heat the one or more droplets when positioned between the top substrate electrode and the first drive electrode of the at least one array element; and circuitry configured to control the heater element.
