Abstract
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.

A backlight module, comprising:
- a backlight control circuit;
- and
- a plurality of light-emitting elements coupled in series and coupled to the backlight control circuit,
- wherein, 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;
- and
- each of the light-emitting elements transmits the packet to a next light-emitting element.
An operation method of a backlight module, comprising:
- transmitting a packet;
- comparing an address of the packet with an individual address of each of a plurality of light-emitting elements of the backlight module by the light-emitting elements of the backlight module, wherein the light-emitting elements are coupled in series;
- when the address of the packet matches the individual address of a target light-emitting element of the light-emitting elements, emitting light by the target light-emitting element according to a light-emitting data of the packet;
- and
- transmitting the packet to a next light-emitting element by each of the light-emitting elements.
