What They Say
An article has been published in the journal, Advance Materials, that explains how a group at NC State University and the University of Texas has developed a new device architecture for organic or perovskite LEDs that can create polarised and directional light directly from the device without external optical elements. The divergence angle of the emitted light is less than 3°. The current efficiency is 2.6 times higher than the reference planar device.
“Because the device we’ve demonstrated is simple to fabricate and can be easily scaled-up, our discovery of this strong directional and polarized light emission from OLEDs and perovskite LEDs has important applications for displays, lighting and other photonic applications,”
Frank So said in a release from NCSU.
What We Think
We are planning a deeper dive into this topic, but very directional light emission with good polarisation would help a lot with optics for applications such as AR and VR headsets. (BR)
