Perception of the Color Change of Temporally Modulated Stimuli

摘要

Organic electroluminescent lighting (OLED) is expected to become one of the next generation lighting devices. However, an OLED panel changes its chromaticity depending on the view angle. In order to index, or quantitatively evaluate, the performance of the OLED panel properly, it is essential to evaluate this property. By simulating this chromatic change with temporally modulated stimuli presented on the monitor, we conducted an experiment to evaluate the perceived magnitude of this chromatic change. In our preliminary experiments, we obtained the results that the subjects perceived the color change to be larger as the change of a* direction increased.
