Abstract:
In an image display apparatus using an FED or an organic EL element, image display that is high in illumination uniformity and high in image quality can be performed. A display element with a matrix structure which conducts linear sequential driving which determines the luminance by a current is used, a threshold voltage of a cathode line immediately before one select period has been terminated where a control electrode line is sequentially driven is measured by a threshold voltage measuring section, the measured threshold voltage is recorded for each of the pixels, and a driving signal at the time of selecting the pixel is corrected by using the value of the recorded threshold voltage, to thereby control electric charge that is emitted from a cathode.
