The effect of ambient lighting on the preferred color temperature of television

Abstract

In this study, the preferred correlated color temperature (CCT) of the television was evaluated according to the CCT change of lighting. In the experiment, the laboratory was set up by considering five ambient lighting CCT conditions between 2500K and 6300K. In each environment, the CCT of the TV was changed from 4000K to 11500K, and an experiment was conducted to select the most preferred TV CCT. In general, it was preferred when the CCT of the TV was changed considering the CCT of the ambient light, compared to the viewing environment in which the TV was watched in one environment regardless of the CCT of the ambient light. If the CCT of the light decreases, the CCT of the display should also be lowered. Especially in low-color lighting environments, such as incandescent lights, when the TV's CCT is lowered, the white part of the image appears to be 'real' white and the images were more preferred.
