Not only LED but also OLED (organic LED) is promising technology for lighting in the future, however, there are technical differences in the spectral characteristics and spatial distribution of luminous intensity between these two technologies. The purpose of this research aims to investigate whether subjects would prefer LED or OLED lighting and if they would feel or perform differently under LED or OLED white light, focusing only on the influence of the spectrum. To take into account cultural differences, the experiment was done both in France and Japan. As results of subjective experiments, 3000K seems to be the colour temperaturepreferred in France and in Japan for reading and playing. Psychological evaluation questionnaires and heart rate measurements indicate that there is no significant soothing effect coming from the white light produced by LED panels or OLED panels, at illuminance levels of 60 lux in the eye.
