Abstract
Disclosed is a subpixel circuit 310 comprising: a first switching device 311 responsive to a digital periodic signal VP to provide a digital control signal VC relating to a digital data signal VD, the digital periodic signal VP defining 2N+1 time slots within each frame cycle, where N is a predetermined integer. The digital data signal VD has a predetermined value at a predetermined one of the 2N+1 time slots; and the subpixel circuit 310 further comprises a second switching device 312 responsive to the control signal Vc to drive an associated light emitting element 320.
