China-based Valiant announced plans to spin-off its OLED production subsidiary, Yantai Gem Chemicals. 

Yantai Gem Chemicals was established in 2005, and it produces intermediate materials for OLED panels (and other applications). If Valiant is successful in its plan, Yantai Gem will list in Shanghai's stock exchange. Following the spin-off, it will become an independent company, while Valiant will remain the major shareholder.

LG Display showed its WOLED roadmap during the K-Display conference in Seoul, saying that it will soon start producing 32-inch (16:9), 34-inch (21:9) and 39-inch (21:9) models.  These panels are aimed for computer monitor applications, rather than TVs, although the 32-inch could also be used as a TV panel.

LGD did not detail when it expects to start producing these panels. Dough already unveiled a few weeks ago that it is working on a 32" monitor, and this will be base on an LGD WOLED panel

The OLED market is always innovating the technology industry, and the Thin Film group at INFICON is here to help OLED manufacturers grow that innovation. INFICON has developed Magnesium Sensitive OLED and High Precision Sensor Crystals, specifically for the OLED market to preserve the high stability and reproducibility of OLED processes.

The Mg Crystal Advantage

Magnesium Sensitive Crystals fill a significant gap in the manufacturing of OLED displays. Up until now, there was no solution for the difficulties of realizing fast magnesium (Mg) detection. Manufactures had to work around this delay by precoating crystals, an added step that not only adds a substantial amount of time to the process, but also wastes material, which in turn, costs more money and is not sustainable. The revolutionary development of Mg Sensitive OLED Crystals removes these unnecessary, wasteful precoating steps. The difference between current crystal products (green data) and the INFICON Mg Sensitive OLED Crystals (purple data) is substantial is shown below:

In May 2022 we reported that China-based OLED lighting developer Yeolight Technology is starting to build a 4.5-Gen OLED lighting production line, in Huaibei City, Anhui Province, China. The company is now starting to move in and install the first production equipment. The total equipment cost is estimated at 800 million Yuan (about $111 million USD). 

Yeolight says that the new fab, when complete, will have a capacity of around 7 million panels in a year, or 1.2 million automotive lighting modules (probably referring to rear light modules). This will be the world's largest OLED lighting fab, when complete.

LG Display reported its financial results for Q2 2023, with revenues of 4.74 trillion Won ($3.7 billion USD) - up 7% from last quarter, and an operating loss of 881 billion Won ($690 million USD). LGD says that demand for display panels increased during the quarter.

LGD is on track to begin mass production of medium-sized panels in the first half of 2024, building a new 6-Gen production line, that is reportedly aimed to supply for Apple's iPad Pro, the first Apple tablet to sport an AMOLED display.

Apple recently announced the Apple Vision Pro VR headset, with dual 4K OLED microdisplays produced by Sony. Sony's production capacity was known to be limited, and it was estimated that its entire capacity is around 900,000 units per year.

A new report by the Financial Times now suggests that Apple originally planned to produce around a million Vision Pro units in 2024, but it has scaled down its plan and now aims to produce only 150,000 units. The reports suggest that critical components are to blame, but it remains to be seen whether Apple will actually be able to sell a large number of these highly expensive devices.

AU Optronics has a 4.5-Gen AMOLED production line in Singapore, active since around 2013. The AFPD line is a small-scale operation, and AUO never managed to expand its capacity and compete with large AMOLED producers.

According to a report from Japan, AUO is now considering closing down the AFPD line, and converting it to microLED R&D production line. It could move it back to Taiwan, or retain Singapore as a hub for AUO in Southeast Asia. The company will make a final decision, it seems, in early 2024.

Industrial laser developer Coherent announced a new Monaco industrial ultraviolet (UV) femtosecond laser with 50 W of output power. The company says that the new laser, the first 50 W 400 fs UV laser with proven 24/7 industrial-grade performance, is ideal for high-speed, high-volume cutting of stacked-OLED displays. 

This laser is used to cut the OLED displays after they are fully produced, which is why Coherent uses the term stacked-OLED (it does not refer to an OLED display with a stacked - or tandem - emitter design). The laser cutting enables shapes, notches and holes. Coherent updates that it installed over 800 Monaco laser systems worldwide (not all at OLED display fabs, though, the Monaco systems are also used in other applications).

A few months ago we reported that Japan-based inkjet printing OLED developer JOLED has filed for bankruptcy, and that Japan Display (JDI) will take over JOLED's technology and operations. JDI released an official statement regarding JOLED and its plans for the future.

So indeed on March 7 2023, JDI signed a basic agreement to support JOLED. Since then the two companies held 'extensive discussions', following which JDI decided to form a subsidiary company called 'JDI Design and Development' or JDIDD, that will acquire JOLED’s OLED technology development business and all related operations.

China-based Visionox demonstrated many OLED displays and new technologies at Display Week 2023.

So first up, we have some rollable and foldable OLEDs. You can see some impressive looking such flexible OLEDs in the video above, and Visionox featured many such displays at their booth.
