Technology of the direct bonded signage display that we developed can easily convert a glass space to digital signage by spot construction. For evaluating its outdoor visibility, we built an artificial ambient illumination environment of 10000 lux, and evaluation methods for bright conditions considering contrast sensitivity function. We found improved contrast ratio of 1.2 times and visibility of gradation difference.
