摘要: A method and system is disclosed for modifying the pulse width modulation signal frequency controlling backlight illumination intensity of a liquid crystal display. The modified selected to eliminate visible light dark bands in display image. brightness may be also adjusted by duty cycle signal. selected, either automatically or user, matched with insure that will anti-phased across plurality contiguous frame refresh periods.
