Burst dimming

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 76.6.165.252 (talk) at 13:13, 15 August 2012 (It is used for LED backlights too). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

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.
