ABSTRACT:
To correct brightness by measuring with accuracy and high speed variation of the brightness between pixels of an organic EL display. A first correction data memory stores a first correction data Dhy in a row direction, and a second correction data memory stores second correction data Dhx in a column direction. A first operation circuit generates a pixel correction data DH based on the first correction data Dhy and the second correction data Dhx. The pixel correction data DH is stored into a pixel correction data memory. Input gray scale data Din is corrected by the pixel correction data DH to output as output gray scale data Dout.
