Backlight assembly

摘要

A backlight assembly includes a light source unit, at least one block driving unit, a controller unit and a noise removing circuit. The light source unit includes a plurality of dimming blocks generating light. The block driving unit drives the dimming blocks. The controller unit controls the block driving unit. The noise removing circuit is connected to the block driving unit and the controller unit to prevent noise from being applied to a reset terminal of the block driving unit.

1. A backlight assembly comprising:
a light source unit comprising a plurality of dimming blocks; at least one block driving unit driving the dimming blocks; a controller unit controlling the block driving unit; and a noise removing circuit connected to the block driving unit and the controller unit to remove noise from a reset terminal of the block driving unit, wherein the controller unit:
transmits a data signal, for controlling the dimming blocks, to a data terminal of the block driving unit;transmits a clock signal, which synchronizes the data signal, to a clock terminal of the block driving unit;transmits a reset signal, for resetting the block driving unit, to the reset terminal of the block driving unit; andtransmits a shutdown signal, which determines whether the block driving unit operates, to a shutdown terminal of the block driving unit,wherein each dimming block includes at least one light-emitting diode, wherein a first signal line connects the controller unit to the reset terminal for transmission of the reset signal, and wherein a second other signal line provides an output of the noise removing unit to the reset terminal.
