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 2):
The circuit arrangement according to  claim 1 , wherein the generator comprises:\n a pulse width modulation control circuit, configured to receive the sync signal from a video processing circuit, wherein the pulse width modulation control circuit checks a frequency of the sync signal, the pulse width modulation control circuit multiplies the frequency of the sync signal to generate a multiplied sync signal when the frequency of the sync signal is lower than a threshold frequency, the pulse width modulation control circuit serves the sync signal as the multiplied sync signal when the frequency of the sync signal is higher than the threshold frequency, and the pulse width modulation control circuit generates the pulse width modulation signal according to the multiplied sync signal; and a backlight driving circuit, coupled to the pulse width modulation control circuit to receive the pulse width modulation signal, and configured to drive the backlight source of a display panel according to the pulse width modulation signal.
