Patent ID: 8531388

Claim:
A liquid crystal display, comprising: a liquid crystal display panel including data lines and gate lines; a data driving circuit configured to drive the data lines; a gate driving circuit configured to drive the gate lines; a plurality of light sources configured to provide light to the liquid crystal display panel; 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 plurality of light sources; a timing controller configured to divide a unit frame period into a first sub-frame period and a second sub-frame period 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 plurality of light sources during the first sub-frame period and turn on all the plurality of light sources at a turn-on time within the second sub-frame period, wherein the light source control circuit includes a data modulation unit configured to divide the liquid crystal display panel in a plurality of blocks along a longitudinal direction and increase the modulation width of the unit frame data as a distance between the display location of the unit frame data on the liquid crystal display panel and a middle block of the plurality of blocks increases.
