Patent ID: 7812808

Claim:
A liquid crystal display, comprising: a liquid crystal panel assembly having a plurality of scanning regions that each include a plurality of pixels; a plurality of light source units supplying light to the plurality of scanning regions, respectively; a data driver that selects gray voltages for a frame of image signals and applies the selected gray voltages to the plurality of pixels as data signals; and a light source controller that controls the turning on and off of light sources of the light source units, a signal controller dividing a frame into a plurality of fields, the light source controller turning off the light sources during a field adjacent to a different frame in the plurality of fields, wherein the light source units supply light to the scanning regions whenever an operation of applying the selected gray voltages to the scanning regions is finished, and during a time when a light source unit supplies light to a corresponding scanning region, at least one scanning region different from said corresponding scanning region is applied with data signals.
