ABSTRACT:
A method for synchronizing a light source control signal with modulation of a display includes the steps of receiving a video signal including a synchronization signal (e.g., a Vsync signal) and using the synchronization signal to generate a light source control signals at high and low values. The light source control signal is pulsed between its high and low values between subsequent synchronization signals to cause a light source to produce light pulses at the same time over each frame of the display. Optionally, the low and/or high time periods are adjustable. A novel display driver is also disclosed and includes an input terminal for receiving the synchronization signal, a light source driver for generating the light source control signal in response to the synchronization signal, and an output terminal for providing the light source control signal to a light source control unit.
