  • Method for synchronizing a display horizontal synchronization signal with an external horizontal synchronization signal
    Patent number: 9236031
    Abstract: Adjust a vertical blanking interval of a display horizontal synchronization signal, according to a difference between an external horizontal synchronization signal and the display horizontal synchronization signal, for synchronizing the display horizontal synchronization signal to the external horizontal synchronization signal. This only requires one or two frames to synchronize the display horizontal synchronization signal to the external horizontal synchronization signal, and will not cause the user to perceive display pauses or flickers.
