Maskless OLED production

Applied Materials announced a technology, branded as MAX OLED that enables OLED display production on large glass substrates, aiming to provide a cost-effective solution to produce TV and TV displays. Applied developed and patented a new OLED pixel architecture and a "dramatically different manufacturing approach" that the company says enables brighter, clearer, more energy-efficient and longer-lasting.

Applied's new MAX OLED systems can scale from 6-Gen substrates to 8-Gen substrates, supporting the new wave of IT OLED production lines. Applied says that its new solution has strong customer interest - and already achieved repeat orders from several leading display makers. Specifically, Applied announced that it will supply an R&D system to Samsung Display that will test the new production technology for its AMOLED and QD-OLED production technologies.

In 2022, Japan Display (JDI) announced that it has developed a "historic breakthrough in display technology" - a new OLED deposition process which they refer to as eLEAP, that is said to be cost effective and can be used to create freeform OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM).

JDI is building a small-scale 6-Gen eLEAP production line in Mobara, Japan, with plans to begin production before the end of 2024. The company is also planning to establish a 8.7-Gen eLEAP fab in Wuhu, Anhui Province, China, and in April 2024 it said it hopes to sign the agreement with Wuhu's Economic and Technical Development Zone (WEDZ) by October 2024. Now JDI has made a rather confusing announcement, saying that while it decided not to extend its current MOU with the WEDZ.

Reports from Korea suggested that Samsung Display acquired 5 patents from US-based Orthogonal, that contains the company's mask-less OLED production process. With this purchase, SDC has a path towards developing its own maskless OLED production.

Maskless OLED production is of high interest lately, as these technology could offer higher pixel aperture ratio leading to higher efficiency, brightness and lifetime and brighter OLEDs, compared to FMM-based production processes. JDI for example claims its eLEAP technology enables an 2X increase in brightness and a 3X increase in lifetime, coupled with reduced production costs.

During Displayweek 2024, Visionox demonstrated many OLED display technologies and panels, and also an interesting microLED prototypes (produced by its subsidiarity Vistar).

Visionox is in the final stages of development of its ViP maskless display production process, and the company showcased some nice ViP smartphone panel prototypes (the technology can be used for any panel size). ViP offers a high improvement in aperture ratio (69% up from 29%) which results in low power consumption and brightness (up to 4X according to Visionox), improved lifetime (up to 6X), improved PPI and more.

JDI is planning to establish a 8.7-Gen eLEAP fab in China, and it is also building a smaller-scale 6-Gen eLEAP production line in Mobara, Japan. The company announced that the 6-Gen Mobara fab is advancing ahead of schedule, and production of eLEAP panels will begin before the end of 2024. JDI developed 14" laptop panels that are three times brighter than other OLEDs (at 1,600 nits), and is also targeting smartwatches, smartphones and automotive displays. JDI is also looking into adopting a tandem structure, to increase brightness even further to 3,000 nits.

Japan Display announced an agreement with China-based LCD maker HKC Corp to mass produce panels by 2025 in China, based on JDI's technology, but the plan was later cancelled, and JDI said it will establish its own factory in China. This project saw delays and was scaled-down in December 2023, and yesterday JDI announces that it again delays the project - now hoping to sign the agreement with the Wuhu Economic and Technological Development Zone by October 2024.

Japan Display announced an agreement with China-based LCD maker HKC Corp to mass produce panels by 2025 in China, based on JDI's technology, but the plan was later cancelled, and JDI said it will establish its own factory in China. The company was negotiating with the Wuhu Economic and Technological Development Zone (in Anhui Province), aiming to establish two eLEAP AMOLED production lines by 2025. JDI hoped to sign the formal agreement before the end of 2023.

JDI now announced that it is scaling back its plans. Originally JDI aimed to establish two production lines: one 6-Gen (with a capacity of 10,000 monthly substrates) and one 8.7-Gen (30,000 monthly substrates). Now JDI decided to reduce its plans, to a single 8.7-Gen fab. In addition, it estimates it will sign the final contract in March 2024. The 8.7-Gen line will start mass production in December 2026.

Visionox announced that it has produced the first mass-production sample ViP AMOLED display. The company aims to start mass producing small and medium-sized ViP AMOLED soon, and later apply the technology for large-area panels as well.

The company did not detail when it expects to start actual mass production. It did update that it has already applied for over 500 patents regarding to ViP technology, over 13 different technical fields. The company also says it is in talks with several key customers to define its production process and final display capabilities.

The company now says that it is progressing with its negotiations with the Wuhu Economic and Technological Development Zone (in Anhui Province), and the hope is to reach a final agreement will be reached by the end of the year. Interestingly, JDI also says that it is considering building an eLEAP AMOLED fab in India, but we do not have more details.

A report from Korea's The Elec publication says that Samsung Display is highly interested in next-generation OLED deposition technologies, that are not based on a metal mask (FMM). Several companies are developing and commercialization such technologies. As these may enable higher-performance OLED production, Samsung Display is interested.

A few months ago we reported that SDC is interested in SEL's maskless production technology, and indeed the new The Elec report states that the two companies are in talks. SEL is one of the three companies we are aware of that have advanced maskless technologies, the other two being Visionox and Japan Display. Samsung Display is mostly interested in a technology that it can exclusively license as it does not want other companies to produce OLEDs using the same technology. Both Visionox and JDI are interested in using their technologies in-house, which is a problem for SDC.
