A backlight module is provided. The backlight module includes a backlight control circuit and a plurality of multiple light-emitting elements coupled in series and coupled to the backlight control circuit. The backlight control circuit transmits a packet. Each of the light-emitting elements compares an address of the packet with an individual address of each of the light-emitting elements. When the address of the packet matches the individual address of a target light-emitting element of the light-emitting elements, the target light-emitting element emits light according to a light-emitting data of the packet. Each of the light-emitting elements transmits the packet to a next light-emitting element.
