Abstract:
A circuit arrangement for controlling a backlight source and an operation method are provided. The circuit arrangement includes a generator. The generator receives a sync signal and generates a pulse width modulation signal synchronous with the sync signal to control the backlight source. The sync signal indicates a frequency of a video including a series of image frames. The sync signal includes a sync period corresponding to a frame of the video. The pulse width modulation signal includes a first waveform pattern in a first sub-period of the sync period and a second waveform pattern in a second sub-period of the sync period. Each of the first waveform pattern and the second waveform pattern includes at least one active pulse. The first waveform pattern is substantially identical to the second waveform pattern.

Claim (Index 6):
The circuit arrangement according to  claim 2 , wherein the pulse width modulation control circuit comprises:\n a frequency checking circuit, configured to receive the sync signal from the video processing circuit and check the frequency of the sync signal, wherein the frequency checking circuit multiplies the frequency of the sync signal to generate the multiplied sync signal when the frequency of the sync signal is lower than the threshold frequency, and the frequency checking circuit serves the sync signal as the multiplied sync signal when the frequency of the sync signal is higher than the threshold frequency; and a pulse width modulation signal generating circuit, coupled to the frequency checking circuit to receive the multiplied sync signal, and configured to generate the pulse width modulation signal to the backlight driving circuit according to the multiplied sync signal and determine a duty ratio of the pulse width modulation signal according to a duty ratio parameter.
