Circuit for compensating a display defect in a video
display device of the present invention includes a memory having position information on a plurality of regular patterned defective regions of a display panel, gray scale section information, a defect
level data on each of the regular patterned defective regions, and a plurality of compensation data on each of the defect
level data stored therein, a first compensation unit, upon reception of data to be displayed on the regular patterned defective regions, for determining defect
level data on the regular patterned defective regions of the data to be displayed, selecting a compensation
data set on the defect level data determined thus, and selecting a compensation data on the data to be displayed from the compensation data selected thus, for compensating the data to be displayed, and a second compensator for distributing the data compensated thus at the first compensation unit spatially and temporally by using
dither patterns for making fine compensation, thereby suppressing
size increase of the compensation data.
