A backlight driving circuit includes a light driving unit, which includes a constant current unit, and a light source operated by the constant current unit. The light driving unit further includes a feedback control unit and a detection circuit. The detection circuit detects the light source and outputs at least a voltage feedback signal to the feedback control unit. The feedback control unit obtains a prestored power parameter corresponding to the voltage feedback signal and outputs an adjusting signal to the constant current unit to adjust the constant current of the light source.

Backlight driving circuit

An exemplary liquid crystal display includes a liquid crystal panel and a backlight module facing the liquid crystal panel. The backlight module includes a light guide plate, a light source and an accommodating frame accommodating the liquid crystal panel, the light guide plate and the light source. The accommodating frame includes a plurality of side walls. The side walls define an absorbing portion and a reflecting portion thereat. The absorbing portion is adjacent to the liquid crystal panel and is configured for absorbing light beams leaking from a periphery of the liquid crystal panel. The reflecting portion is adjacent to the light guide plate and is configured for reflecting light beams leaking from at least one peripheral portion of the light guide plate.
