Abstract
A correction circuit includes a memory that stores a mobility correction value or a threshold voltage correction value for correcting luminance non-uniformity for every pixel, a memory read-out unit that reads out the mobility correction value or the threshold voltage correction value from the memory, a correlation table that produces a threshold voltage correction value or a mobility correction value from the other one of the mobility correction value and the threshold voltage correction value on the basis of a correlation between mobility and a threshold voltage, a mobility correction unit correcting an input signal for every pixel by using the mobility correction value supplied from the memory read-out unit or the correlation table, and a threshold voltage correction unit correcting the input signal that is corrected at the mobility correction unit, by using the threshold voltage correction value supplied from the memory read-out unit or the correlation table.
