Abstract:
1. A driving method for local dimming of a Liquid Crystal Display (LCD) device, comprising: assigning a first block index to each of a plurality of blocks into which backlight unit is divided; detecting a connection order of the plurality of blocks in the backlight unit, arranging the first block indexes according to the connection order of the plurality of blocks, and storing first block index ordering information that specifies the arranged first block indexes; retrieving the stored first block index ordering information; generating second block index information that specifies second block indexes corresponding to the first block indexes of the backlight unit; determining a local dimming value for each block by analyzing input data on a block basis according to the second block index information; rearranging the local dimming values arranged based on the second block index information according to the first block index ordering information; and driving the plurality of blocks respectively using the rearranged local dimming values of the plurality of blocks.
