In this paper we propose a method based on the properties of human spatial color perception for calibration of self-
luminous display with significant non-uniformity of the peak brightness. The method maximizes the perceived image
uniformity. Compensation of the image non-uniformity is based on minimizing the S-CIELAB distance between the target and
the displayed image. This optimization problem was solved using descent methods similar to those used in the training of
convolutional neural networks. The application of this method is promising for use in large format LED displays.
Key words:
photoemission display, display calibration, display non-uniformity compensation, human visual system model, S-CIELAB
