Abstract

The effect of the level of transmission and surround luminance on image quality of transparent display is studied. The images on the OLED transparent display were simulated on LCD monitor by adding background scene to the original images. The psychophysical experiment was carried out on normal and simulated transparent displays under four levels of surround luminance (dark, dim, average and bright) and four different levels of transmission (17, 52, 70 and 87%). Four test images were selected for the psychophysical experiment. Fifteen subjects were participated in this experiment and they were asked to answer the degree of preference of each image for each condition with 7-point Likert-scale. As the result, it is found that the image quality of OLED transparent display deteriorates as the surround luminance increases and the transmittance increases but lowering the monitor gamma can be helpful to increase the image quality. This result suggests that image quality requirement for a transparent display is different from conventional opaque displays.
