Photos: Lights going organic

Universal Display has developed prototypes of transparent OLED screens. The terms PHOLED, TOLED and FOLED stand for different OLED (organic light-emitting diode) properties. A PHOLED is a phosphorescent OLED and can convert up to 100 percent of the electricity, theoretically, into light. TOLEDs are transparent, while FOLEDs are flexible. All three properties can be integrated into a single OLED.
