Burst dimming

Burst dimming

Burst dimming is a method to control dimming of cold cathode fluorescent lamps (CCFL) 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. [cite web|title=Electrical Engineering Glossary Definition for Burst Dimming - Maxim/Dallas|url=http://www.maxim-ic.com/glossary/index.cfm/Ac/V/ID/998/Tm/Burst-Dimming 070925 maxim-ic.com] This technique is sometimes used with TFT displays to control Backlighting. An alternative dimming method is to control lamp current.
