Abstract
A light emitting diode (LED) circuit for preventing parasitic current flow through a first LED when the first LED is in an off state is described, where the parasitic current flow is a result of one or more parasitic capacitances, the LED circuit comprising the first LED, and a first current switch coupled to the first LED and arranged to enable a current flow through the first LED when the first current switch is in an on state, where the first current switch is arranged to discharge the one or more parasitic capacitances when the first current switch is in the on state.
