Advances in Solid-state Lighting Promise Higher Energy Efficiency and Greater Design Flexibility

Considering the growing importance of energy savings and environment friendliness, solid-state lighting is emerging a highly competent and viable alternative to existing lighting technologies. While light emitting diodes (LEDs) promise numerous advantages such as higher energy efficiency, longer life and reliability, as well as low temperature performance, customer requirements for innovative solutions that provide better control over the color, shape, and intensity of light is driving the demand for organic light emitting diodes (OLEDs) as light sources.
In respect to OLEDs, industry participants need to overcome key challenges such as outcoupling and sensitivity issues in order to increase the light output. Since increasing light output is dependent on the device technology and the chemistry of materials involved, the challenge lies in making the lifetime of the generated photon’s last nano or microseconds.
