摘要： A method of driving an active matrix electro-wetting on dielectric (AM-EWOD) device comprises (i) setting a reference electrode to a first reference voltage; (ii) writing a set of data to array element electrodes of array elements of the device; and (iii) either (a) maintaining the voltages written to the array element electrodes until a time t0 or (b) re-writing the set of data N−1 times (where N≧2). The reference electrode is then set to a second reference voltage different from the first reference voltage, and features (i) to (iii) are repeated. When the data are first written, there is a delay between the time when the voltage on the reference electrode is transitioned and the time when a given array element is next written with data. Feature (iii) allows the time for which the correct data values are held to be increased relative to the time for which incorrect data values may possibly be held, so that the time for which an element may be in an incorrect state can be made insignificant in terms of its effect on unwantedly perturbing droplet operations.

摘要： A method of driving an element of an active matrix electro-wetting on dielectric (AM-EWOD) device comprise applying a first alternating voltage to a reference electrode of the AM-EWOD device; and either (i) applying to the element electrode a second alternating voltage that has the same frequency as the first alternating voltage and that is out of phase with the first alternating voltage or (ii) holding the element electrode in a high impedance state. The effect of applying the second alternating voltage to the element electrode is to put the element in an actuated state in which the element is configured to actuate any liquid droplet present in the element, while the effect of holding the element electrode in the high impedance state is to put the element in a non-actuated state.
