The outdoor use of digital tools such as AR is anticipated, but there is a problem that the content is hard to see when a normal PC display is used. In this study, to clarify the reason for this, luminance, the contrast ratio, and the viewing angle of a display designed for outdoor use were measured according to each step of 16 luminance settings in a darkroom and outdoors. Two methods of obtaining stable data of display luminance were considered, namely construction of a pilot machine which can make artificial lighting with stable environment and a computer simulation.
