Abstract:
1. A backlight assembly comprising: a plurality of linear light sources each having a high-voltage end and a low-voltage end, arranged in parallel behind a display screen, the plurality of linear light sources being divided into a first group and a second group, the linear light sources belonging to the first group being oriented in a first direction, the linear light sources belonging to the second group being oriented in a second direction opposite to the first direction; a first inverter substrate having a plurality of first inverter circuits formed therein corresponding to the plurality of the linear light sources of the first group and configured for driving the linear light sources belonging to the first group in response to control signals from a first control signal input port associated therewith the first inverter substrate; a second inverter substrate having a plurality of second inverter circuits formed therein corresponding to the plurality of the linear light sources of the second group and configured for driving the linear light sources belonging to the second group in response to control signals from a second control signal input port associated therewith the second inverter substrate, the first and second inverter substrates being arranged on respectively opposite sides of the linear light sources, a first return substrate corresponding to the first inverter substrate and connected to the adjacent low-voltage ends of the plurality of linear light sources; and a second return substrates corresponding to the second inverter substrate and connected to the adjacent low-voltage ends of the plurality of linear light sources, wherein the first and second inverter substrates and the first and second return substrates are commonly grounded through a bus line.
