    Abstract: A backlight control device for use in an electronic device includes a motion detecting unit, a sound matching unit and a controller. The motion detecting unit is configured to detect motion of a lid section of the electronic device to generate motion data. The sound matching unit is configured to match a soundprint derived from a sound sample that is captured by a sound capture unit, to one or more sound patterns stored within in a sound pattern database to generate a lid state indication signal if the motion data indicates the motion of the lid section corresponds to a predetermined state. The controller is configured to control a backlight module of a display device of the electronic device according to the lid state indication signal.
