  • LED backlight system
    Patent number: 8907884
    Abstract: A method and system for modifying the pulse width modulation frequency for controlling the backlit illumination intensity of a liquid crystal display. The modified pulse width modulation frequency may be selected to reduce distortion in the display while allowing for a wide range of dimming settings for the display. A pulse width modulation signal may be also be phase shifted such that a string of light sources may be sequentially activated to generate a effective frequency greater than that of the frequency of the pulse width modulation signal.
    Type: Grant
