HUE PERCEPTION AND NEUTRALNESS OF A SMARTPHONE DISPLAY UNDER DIFFERENT SURROUND CONDITIONS

Abstract

Hue perception and Neutralness of a smartphone display were investigated under a total of 4 different surround conditions – 2 Correlated Colour Temperature (7700K and 3900K) and 2 surround lighting conditions (Average and Bright). In the psychophysical experiment, a total of 15 test display white settings were generated on the smartphone according to different surround conditions and ten participants were recruited. Both Hue perception and Neutralness experiment results showed that the display’s white point at 7700K should match the lighting setting to be perceived as neutral. On the other hand, the display must be set bluer than the lighting at 3900K condition. It also has dependence on the surround lighting condition especially at 3900K. When the display is seen as a surface colour in the Bright condition, the display white can be set more similar to the lighting setting than the Average.
