摘要：
An exemplary backlight modulation circuit includes a backlight source, a backlight driving circuit, a rough modulation key, a fine modulation key, a scaler, and an illumination modulation signal processing circuit. The backlight driving circuit is configured for driving the backlight source. The rough modulation key and the fine modulation key are configured for generating a rough triggering signal and a fine triggering signal. The scaler is configured for receiving the rough triggering signal and the fine triggering signal, and generating an illumination modulation signal. The illumination modulation signal processing circuit is configured for receiving the illumination modulation signal, and processing the illumination modulation signal to generate one of a rough modulation controlling signal to modulate illumination of the backlight source in a large range and a fine modulation controlling signal to modulate the illumination of the backlight source in a small range.
