Abstract
A backlight assembly outputs scan signals having a scanning frequency synchronized with a frame frequency to sequentially drive light emitting blocks providing a light to a display panel. A dimming step of each light emitting block corresponds to one of a plurality of dimming steps in response to local dimming data. A dimming clock having a value obtained by dividing a value obtained by multiplying the scanning frequency and the number is dimming steps by a duty ratio of each scan signal is generated. The dimming step of each light emitting block is counted using the dimming clock, and the counted values are combined with the scan signals to generate dimming signals having a dimming duty ratio corresponding to the dimming step of the light emitting blocks.
