Abstract: Recently, transparent displays have drawn much attention as next-generation displays. However, transparent displays suffer from poor visibility because background images are always seen along with the displayed image because of this transparent window area. This visibility problem can be solved by placing a light shutter at the backside of a transparent display. By switching the light shutter, we can block or transmit the background image through a the transparent display. The operational principle of a light shutter can be classified into two types: light scattering and light absorption. For the practical application of the light shutter to a transparent display, a single-layered light shutter, wherein haze and transmittance can be simultaneously controlled, is desirable. In this study, we demonstrate a dye-doped liquid crystal light shutter device that simultaneously uses light scattering and light absorption effects in a single-layered structure.
