Abstract
A driving circuit for an electrowetting on dielectric (EWOD) pixel. The driving circuit includes a latch circuit for transmitting a source data pulse to a storage capacitor in response to an activation gate signal applied to the gate of the switch transistor and generating a latch voltage and an inversion circuit for outputting a driving voltage at either a first power voltage or a second power voltage based on the latch voltage generated by the latch circuit.
