LG Display demonstrates a prototype WOLED display with a microlens MLA array

As we reported last week, LG Display is developing OLED TV panels that utilize a microlens array to increase the light output. LGD unveiled its first prototype display at SID Displayweek 2022.

LGD is showing a 77" 8K panel that features what the company refers to as Meta-lit Lens Array, or MLA technology. The MLA layer increases light output by more than 20%, and the panel achieves a brightness of 2,000 nits. LGD says that the viewing angles is also increased using the MLA technology.

KIST researchers develop a non-destructive method to inspect OLED emitters using terahertz waves

Researchers from the Korea Institute of Science and Technology (KIST) suggest a new method to inspect OLED emitter materials, using terahertz wave spectroscopy.

The researchers say that this method can be used to analyze the transmission characteristics of the OLEDs, without any damage to the materials. This is unlike current fluorescence test methods that harm the OLEDs because of the ultraviolet rays which changes the characteristics.

SolOLED secures $250,000 to develop novel TADF emitters

UK-based SolOLED secured 200,000 GBP (almost $250,000 USD) in new funding from Scottish Enterprise to commercialize its novel OLED TADF emitter materials. SolOLED is launching a collaborative research project with CENSIS to commercialize the materials.

SolOLED was established in 2021 in the UK, to develop a family of novel solution-based TADF OLED emitter, based on technology that originated from the University of St. Andrews.

Updates on Royole's current financial situation

Last month we updated that Royole is in financial problems, and that it needs a new injection of cash in order to continue its operation. A new update from China suggests that some employees did not get paid for over 5 months. This has changed in the past week, and Royole is now paying the salaries.

But Royole's financial woes are likely not over. According to this new report, from 2017 to 2020, the company's revenues amounted to only $77 million, while its loss reached almost $500 million. The report also detailed Royole production: 7,748 units in 2018, 314,000 units in 2019 and 48,600 in the first half of 2020. Actual shipments were much lower.

LG Display could adopt a microLens array in its OLED TV panels to boost brightness and efficiency

Reports from Korea suggest that LG Display is looking into adopting a microLens array in its large OLED TV panel architecture. The microlens layer could boost brightness by up to 20%, which will also increase efficiency (if brightness is kept as before).

According to the report, the project is at an advanced stage, and panels with the microLens array could be introduced by the end of this year. LGD will apply the technology to its OLED.EX panels, so brightness could reach up to 1,200 nits. LGD considers this technology as it faces competition in large-area OLED production, from Samsung's QD-OLED panels, for the first time.
