A Flexible OLED is a surface-emitting light source that is thin, lightweight, and flexible. In spite of unique characteristics, there have been challenges in market development. In order to broaden the market, it is necessary to make clear the TRUE VALUE that only Flexible OLED can provide. At the origin of the TRUE VALUE is the Core value, which is "uniform surface-emitting light in extremely thin installation spaces". The Core value is made stronger by combining the three Boosters which is "Weight reduction", "Twilight control", and "Heatless touch".Ń This TRUE VALUE can be visualized in a triangular diagram.Core value is at the center and surrounded by Boosters. The number of Boosters will be increased with technology. The world of product design will largely change according to next Booster "Invisible magic" established by transparency technologies.
