Patent ID: 7834825

Claim:
An organic EL display apparatus including in each display pixel an organic EL element and a drive transistor that supplies the organic EL element with a drive current that depends on brightness data and having the display pixels arranged in a matrix form, the organic EL display apparatus comprising: a correction gain storage unit for storing display pixel positions and a correction gain for correcting the slope of the brightness-data-based drive current of the drive transistors in the display pixels; and a correction unit for correcting pixel-by-pixel brightness data depending on the pixel position using the correction gain stored in the correction gain storage unit into brightness data for the pixel to generate corrected brightness data, wherein each of the display pixels is displayed by driving its drive transistor in response to the data generated by the correction gain storage unit and the correction unit and supplying the corresponding organic EL element with the drive current; and a correction offset storage unit for storing a display pixel position and a correction offset for correcting an offset for brightness data of the drive transistor in the display pixel for an area having a given plurality of display pixels, wherein the correction unit corrects pixel-by-pixel brightness data depending on the pixel position using the correction gain stored in the correction gain storage unit and the correction offset stored in the correction offset storage unit into brightness data for the pixel to generate corrected brightness data.
