Claim 9:
10. A display driver circuit for controlling a display panel having a plurality of light-emission diode (LED) strings, the display driver circuit comprising:
a plurality of current regulators, each configured to control one of the plurality of LED strings; and
a control circuit, coupled to the plurality of current regulators, configured to generate a plurality of pulse width modulation (PWM) signals and output each of the plurality of PWM signals to a respective current regulator among the plurality of current regulators;
wherein a first PWM signal and a second PWM signal among the plurality of PWM signals have different duty cycles for generating substantially identical brightness on corresponding LED strings among the plurality of LED strings in the same frame period.
