Burst dimming is a method to control dimming of cold cathode fluorescent lamps (CCFLs) and LEDs by using pulse width modulation (PWM) at approximately 100-300 Hz which is supposed to be above the noticeable flicker limit for the human eye. [1] This technique is sometimes used with TFT displays to control backlighting. An alternative dimming method is to control lamp current.
