Claim 6:
7. A system comprising:
a frame rendering subsystem configured to render a sequence of frames at a variable rate; and
a display control subsystem coupled to the frame rendering subsystem and coupleable to a display panel, the display control subsystem configured to:
provide a brightness control signal to the display panel, the brightness control signal configured to control a brightness of frames displayed at a display panel via pulse width modulation (PWM) of the brightness control signal;
select, for display of frames at the display panel, a target frame rate that is between a minimum frame rate and maximum frame rate and which is an integer divisor of a PWM frequency of the brightness control signal so that a corresponding frame period for the target frame rate is an integer multiple of a PWM period of the brightness control signal; and
transmit frames to the display panel for display based on the target frame rate such that a frame period of each frame is aligned with a corresponding PWM cycle of the brightness control signal.
