The preferred display color temperature (Non-transparent vs. Transparent Display)

Abstract

The preferred color temperature of a non-transparent display and an OLED transparent display was investigated. 24-inch LCD monitor was used to simulate both types of displays shown under two-different background color temperature (3000K and 6500K) conditions. Twenty observers participated the psychophysical experiment in a dark room. They were asked to choose the most preferred display image among the images having 9 different color temperatures. The results showed that as the color temperature of the surround decreases, the preferred color temperature of the monitor also decreases. Also it is found that the preferred color temperature of the total white (the monitor white plus transmitted light) of OLED transparent display is similar with that of the nontransparent display.
