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.
