Abstract

A backlight apparatus includes a circuit board, a control board, and a connection cable connecting the above components. A first light source driver and a second light source driver are disposed on the circuit board and are electrically connected to a plurality of first light sources and a plurality of second light sources respectively. A connector is disposed on the circuit board. The first and second light source drivers are individually electrically coupled in series to the connector. The control board outputs electrical power, a first data stream, and a second data stream. The first light source driver controls the plurality of first light sources to light individually according to the first data stream. The second light source driver controls the plurality of second light sources to light individually according to the second data stream. Thereby, the circuit board can control the operation of the light sources individually.
