SELF-LUMINOUS DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a self-luminous display device that always obtains uniform light emission characteristics of all pixels on a screen by correcting initial luminance unevenness of each pixel and image persistence due to degradation in light emission characteristics of each pixel caused with the elapsed time.

SOLUTION: A video display part 7 includes a plurality of pixels each comprising a light emitting element whose brightness is controlled with a current amount, and a light emission control part which controls amounts of currents flowing to light emitting elements of the plurality of pixels for each pixel based upon reference video data. A luminance unevenness correcting means 3 corrects initial luminance unevenness of each pixel for the reference video data using a luminance unevenness correction coefficient therefor. An image persistence correcting means 8 inputs corrected video data subjected to the luminance unevenness correction by the luminance unevenness correction means, calculates input video data obtained by correcting the corrected video data for each pixel based upon luminance unevenness correction coefficients, and corrects image persistence of each pixel of the video display part.
