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 19):
The operation method according to  claim 17 , wherein the step of generating the pulse width modulation signal comprises:\n generating, by a period defining circuit, a first enablement signal and a second enablement signal according to a timing of the multiplied sync signal, wherein the third sub-period is defined by the first enablement signal, and the fourth sub-period is defined by the second enablement signal; generating a first pulse width modulation signal in the third sub-period according to the first enablement signal and determining a duty ratio of the first pulse width modulation signal in the third sub-period according to a duty ratio parameter by a first pulse width modulation signal generating circuit; generating a second pulse width modulation signal in the fourth sub-period according to the second enablement signal and determining a duty ratio of the second pulse width modulation signal in the fourth sub-period according to the duty ratio parameter by a second pulse width modulation signal generating circuit, wherein a frequency of the second pulse width modulation signal is different from a frequency of the first pulse width modulation signal; and superimposing, by a superimposing circuit, the first pulse width modulation signal and the second pulse width modulation signal to obtain the pulse width modulation signal.
