Reports from Korea suggest that Meta (Facebook) is in talks with both Samsung Display and LG Display, regarding the supply of OLED microdisplays and microLED microdisplays for its future AR and VR glasses.

According to the reports, dozens of executives from Meta have met with executives from LG Display and Samsung Display, and the discussions are still ongoing. According to other reports, Meta plans to use OLED displays in its upcoming VR glasses, and MicroLEDs in AR glasses that will hit the market at around 2026.

In December 2021, LG Display unveiled its OLED.EX (Evolution and eXperience) technology, that are based on deuterium-enhanced compounds to increase brightness by up to 30%. The company now announced that it has completed upgrading all of its WOLED TV production lines (in Korea and China) to EX technology, and all new panels will use the new materials.

LG Display says to develop the OLED.EX technology, it has converted the hydrogen elements present in organic light emitting elements into stable deuterium. LGD extracts the deuterium compounds from water, and after stabilization, the compounds allow the OLED devices to be brighter - and also last longer.

Researchers from Korea's KAIST institute developed a fabric-based wearable patch that uses a blue OLED device to treat jaundice in newborns.

The researchers say that phototherapy is the most widely used treatment for neonatal jaundice, as it is a safe and effective to transform the bilirubin that is accumulated in the body and release it. When the bilirubin concentration is too high, the doctors treat newborns with blue light in an incubator. The new device can be used to treat high levels of bilirubin, without the need for an incubator.
