Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel configured to display an image; a backlight unit configured to include: wherein the liquid crystal panel is divided and arranged into a plurality of blocks to be illuminated over a full frame period with light guided by the optical sheet on the same layer of the backlight unit, wherein the full frame period comprises a plurality of time intervals each correspond to a time duration taken to illuminate the plurality of blocks, the plurality of blocks each being illuminated a plurality of times equal to a number of the plurality of time intervals during the full frame period, an input unit configured to receive data corresponding to the image; a brightness analyzer configured to analyze the data from the input unit in blocks, and to derive logic signals from the analyzed brightness data corresponding to the image data of each block, depending on a specific algorithm; a lamp control signal generator configured to derive lamp control signals from the logic signals controlling a turning-on/off time of each of the plurality of first and the second light sources from the logic signals; and a lamp driver configured to drive each of the plurality of the first and the second light sources with the lamp control signals from the lamp control signal generator, wherein the brightness analyzer provides the logic signals according to logic values stored in a register, wherein the register includes the plurality of the first channels and the plurality of the second channels corresponding to the plurality of the first light sources and the plurality of the second light sources, wherein the logic values are selected from one of a specific logic value or a basis logic value,
