Abstract
A liquid crystal display includes a liquid crystal display panel, a data driving circuit, a gate driving circuit, a plurality of light sources, a light source control circuit configured to differently modulate a unit frame data depending on a display location of the unit frame data on the liquid crystal display panel and to control turn-on and turn-off operations of the light sources, a timing controller configured to divide a unit frame period into first and second sub-frame periods and to repeatedly supply the modulated unit frame data to the data driving circuit during the first and second sub-frame periods, and a light source driving circuit configured to turn off all the light sources during the first sub-frame period and turn on all the light sources at a turn-on time within the second sub-frame period.
