ORGANIC LIGHT-EMITTING DIODE (OLED) WITH RESONANT STRUCTURE

Existing light emitting devices suffer from efficiency problems, such as incomplete light extraction from active layers. This inability to direct light from the diode results in an 180˚ active range of light emission and power losses.

The OLED with Resonant Structure utilizes two mirrors to increase the radiative efficiency of OLEDs by 80-100 percent. The first mirror is a partially reflective, metallic patch grating resonator that reduces lateral propagation of radiative emissions’ diffusion. The second mirror is a transparent electrode of the OLED, which communicates with the optically active material. Together, these mirrors almost double the output power of the LED.
