An IDC Analyst estimates that Apple will start low-volume Micro-LED production in its plant in Taoyuan, Taiwan, by the end of 2017. Mass production will begin in 2018 with an aim to use these displays in future smart watch devices.

Apple acquired Micro-LED developer LuxVue in May 2014 and has not updated on the technology since, so this is all speculation at this stage. In 2016 Oculus acquired InfiniLED, another Micro-LED startup. Sony is also developing Micro-LED displays.

Researchers from the Technical University in Dresden have developed a method to produce polymer TADF emitting molecules. Up until now most TADF materials are based on small molecules or chromophores linked to a polymer network.

This research focused on actual polymer TADF, and using a controlled extension of the conjugation of the monomers HOMO wavefunction, the researchers were able to to increase thephotoluminescence quantum yield from about 3% to about 71%. The reseachers say that this is an encouraging first step towards polymer TADF emitters.

LG Electronics started shipping its OLEDE7 mid-range 2017 OLED TVs. The E7 costs $4,999 for the 55" model and $5,999 for the 65" model. The 65" model is already available at Amazon.com.

The OLEDE7 series is an update to the OLEDE6 series from 2016. These OLED TVs feature 4K resolution, HDR support (four different standards), WebOS 3.5, Dolby Atmos sound and an on-glass design.

Researchers from the University of Cambridge, the University of East Anglia and the University of Eastern Finland developed soluble carbene-metal-amides light emitting materials that were found to be very efficient and reach an internal quantum efficiency of nearly 100% at high brightness.

The new materials look like propellers and the rotation of the molecules changes the light emitting efficiency. Those materials are made from copper or gold, but the researchers aim to find similarly-shaped materials that are free from rare elements.
