Abstract
The LED display system comprises an array of LEDs and a driver circuit that employs a scrambled PWM generator. The scrambled PWM generator is configured to generate a plurality of PWM pulses. The PWM pulses are distributed into a corresponding number of refresh segments. The driver circuit is configured so that one or more of PWM pulses are extendable by a certain offset value so that the pulse width in the corresponding refresh segments is wide enough for the LED to emit light.
