Abstract
A liquid crystal display (LCD) system includes an LCD device and an alternating current (AC) adapter. The LCD device includes a video processing module and a light emitting diode (LED) backlight module. The AC adapter includes a backlight driving module and an AC-to-DC (direct current) converting module. The backlight driving module generates a backlight driving signal, and outputs the backlight driving signal to drive the LED backlight module of the LCD device. The AC-to-DC converting module is adapted to convert an AC line voltage into first and second DC voltages, and outputs the first and second DC voltages to power the video processing module of the LCD device and the backlight driving module, respectively.
