Furthermore, in such a configuration, the photon energies of both the incident ambient light and the portion of OLED emission not getting outside of the device can be recycled into useful electrical power via the photovoltaic action, instead of being wasted as in other reported contrast-enhancement techniques. These features, we believe, shall make this present technique attractive for high-contrast display applications and portable/mobile electronics that are highly power-aware. © Copyright 2008 Society for Information Display.Energy recycling; High contrast; OLED; Solar cell[SDGs]SDG7Electromagnetic waves; Helmet mounted displays; Light reflection; Organic light emitting diodes (OLED); Photovoltaic cells; Recycling; Solar cells; Solar equipment; Ambient light; Display applications; EL efficiencies; Electrical powers; Electronics; Energy recycling; Enhancement techniques; High contrast; OLED; Organic light-emitting devices; Photon energies; Photovoltaic; Power-aware; Solar energyjournal article10.1889/1.29388712-s2.0-54149118939WOS:000256457600006
