Claim 15:
16. A non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate at least one processor to:
control a brightness of frames displayed at a display panel via pulse width modulation (PWM) of a brightness control signal provided to the display panel;
measure a frame start delay associated with a deviation in a duty cycle of a first PWM period of the brightness control signal relative to a default duty cycle resulting from a delay in rendering of a frame, the frame start delay comprising a duration by which the first PWM period is extended compared to a duration of a default PWM period having the default duty cycle; and
adjust a duty cycle of at least a second PWM period following the first PWM period to compensate for the measured frame start delay.
