Angular-dependent color shift is one of the features that should be properly evaluated for OLED panels as their performance. In order to develop an index for this evaluation, we have tried to propose a metric to evaluate this color shift in conjunction with the human perception for continuous color shift. We conducted psychophysical experiments to rate the perceived magnitude of continuous chromatic change. The subjects observed a stimulus whose chromaticity was changed according to the orientation of the tablet which they could freely manipulate. This was intended to mimic the performance of an OLED panel. Three luminance levels and eight different trajectories of color shifts were tested. Our results indicate that the sensitivity for the perception of the continuous color shift decreased as the luminance level increased. On the contrary, the sensitivity increased as the color temperature increased.
