Patent ID: 8164564

Claim:
A liquid crystal display, comprising: a liquid crystal display panel; a light emitting diode device comprising a plurality of partitioned areas, each of the partitioned areas being driven independently of adjacent partitioned areas; a plurality of light guide parts, the light guide parts for guiding light generated from corresponding ones of the partitioned areas of the light emitting diode device toward the liquid crystal display panel; an image calculating part for dividing the liquid crystal display panel into a plurality of regions and calculating brightness of each of the regions by using image data, the regions being arranged along a transverse direction and a longitudinal direction of the liquid crystal display panel; an inverter for providing power to each of the partitioned areas of the light emitting diode device; and an inverter controller for controlling the inverter to provide power to each of the partitioned areas of the light emitting diode device according to the calculated brightness of corresponding regions of the liquid crystal display panel; wherein the provided power to each of the partitioned areas of the light emitting diode device by the inverter has a different level from each other according to the calculated brightness of each of the regions; and wherein the light emitting diode corresponding to the region having a high brightness provides a light of the high brightness, and the light emitting diode corresponding to the region having a low brightness provides a light of the low brightness.
