Patent ID: 8564506

Claim:
A correction circuit, comprising: a memory configured to store one of a mobility correction value and a threshold voltage correction value that are used for correcting luminance non-uniformity for every pixel, the luminance non-uniformity being caused by variations in mobility of a carrier in a channel region and a threshold voltage of a driving transistor included in a pixel circuit of a pixel constituting a display panel and being a correction object; a memory read-out unit configured to read out one of the mobility correction value and the threshold voltage correction value that are stored in the memory; a correlation table configured to produce one of a threshold voltage correction value and a mobility correction value from the other one of the mobility correction value and the threshold voltage correction value that are read out by the memory read-out unit, on the basis of a correlation between the mobility and the threshold voltage; a mobility correction means for correcting an input signal for every pixel by using the mobility correction value supplied from one of the memory read-out unit and the correlation table; and a threshold voltage correction means for correcting the input signal for every pixel, the input signal being corrected at the mobility correction means, by using the threshold voltage correction value supplied from one of the memory read-out unit and the correlation table.
