A system and a method for driving light emitters of a liquid crystal display (LCD) backlight
module is disclosed. The system drives the light emitters by supplying a constant current and
a pulse width modulated current to an individual light emitter, the pulse width modulated
current being determined in accordance with an optical output of the light emitter.
Accordingly, the system can provide a desired amount of current to the light emitters, and
individually control the optical output of the light emitters.
