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.

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.

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.

Nintendo disclosed that it shipped over 5.8 million Nintendo Switch OLED devices, since launching the new gaming console in October 2021.

The Nintendo Switch OLED model is an upgrade to the original Switch with a 7-inch 1280x720 OLED display (produced by Samsung Display). The Nintendo Switch OLED model is now shipping globally for $349.99.

Yesterday we reported on LGD's SID Displayweek exhibition displays, and today the company shared a video with us that shows some of these displays in action:

First you'll see LG's latest 8.03-inch 2480x2200 foldable OLED displays, that can fold both inwards and outwards. The second display is LG's largest WOLED panel, the 97-inch OLED.EX.

Samsung Display unveils new OLED displays at SID Displayweek 2022. First up is the Flex G flexible display, which folds inwards twice, and the Flex S, that can fold both inwards and outwards.

Samsung is also new rollable displays - a 6.7" slidable display that can expand and a larger 12.4" slidable OLED that can expand from both ends. When close, the display is 8.1" in size.

LG Display has unveiled a new foldable OLED panel, that can fold 360-degrees - both inwards and outwards. The panel is 8.03" in size with a resolution of 2480x2200, and has been tested for over 200,000 folding cycles. LGD says it developed a special folding structure to minimize creasing.

LG is also showing other technologies and panels - a 17" folding display for laptops, a 97-inch OLED.EX TV panel, a bendable 42-inch gaming display and its 55" touch-enabled transparent OLEDs.

Canada-based OTI Lumionics started shipping its 2nd-gen ConducTorr Cathode Patterning Materials (CPM) by the end of 2020 to customers, which are used to create OLED displays with under-the-display camera and face unlock technologies.

OTI Lumionics now announced that it signed an agreement with EVM OLED mask maker Dai Nippon Printing. Dai Nippon will optimize its EVM masks for the deposition of OTI's CPM materials.

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.

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.
