Abstract:
1. A method for setting a compensation region for an irregular defect region, comprising the steps of: detecting an irregular display defect; setting a horizontal width of the irregular defect region detected thus; generating a plurality of guide lines which divide the irregular defect region in a horizontal direction along the horizontal width set thus, automatically; setting upper and lower side boundary lines to the irregular defect region at every interval of the plurality of the guide lines to generate a plurality of main compensation regions defined by the plurality of guide lines and the upper and lower side boundary lines; and generating a plurality of upper, lower, left, and right supplementary compensation regions at upper, lower, left, and right sides of the plurality of main compensation regions, which maintain a gap of each of the plurality of the guide lines, automatically, wherein a width of each supplementary compensation region is the same as a width of each main compensation region, and wherein the widths of the main compensation region and the supplementary compensation region is set to multiples of a size of a dithering pattern, the dithering pattern used for compensation of brightness in a compensation circuit.
