Samsung Display reportedly decided to use 8.7-Gen glass substrates in its upcoming IT OLED fab

OLED makers are gearing up to increase production of IT OLED panels, used in laptops, monitors and tablets. Towards that, analysts expects over 10 8.5-Gen OLED lines under consideration now in the industry. This drive is led by Samsung Display that confirmed is is building a 8-Gen (2200x2500 mm) OLED production line, that will begin production in 2024.

A 8-Gen (or actually 8.5-Gen) fab uses 2200x2500mm glass substrates. According to a new report in Korea, Samsung actually decided to adopt a larger glass - a 8.7-Gen 2290x2620 mm. The ~10cm increase will increase production efficiency by around 9%, but this means that current 8.5-Gen LCD equipment that Samsung hoped to use will not be usable any more.

Merck’s local OLED production will give Merck’s China-based and Asia-based customers easier and faster access to OLED materials and a stable and more flexible supply chain.

A report suggests that Samsung Display is interested in JDI's eLEAP OLED deposition technology

A few months ago, 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).

According to a new report from Korea, Samsung Display is interested in JDI's new technique. Interestingly the report shows conflicting views within SDC - some are interested in adopting this new technology, especially at SDC's upcoming 8-Gen IT OLED production line, while others are more interested in preventing SDC's competitors (JDI, or others?) from using it, perhaps by pressuring OLED equipment makers to not offer needed equipment to JDI.

INFICON details its Magnesium-Sensitive Crystal for OLED deposition

This is a sponsored post by INFICON

OLED producers have been struggling with the deposition of magnesium materials during the OLED production process. INFICON has developed high-level magnesium-sensitive crystals specifically for OLED deposition, that significantly shorten the initial time delay in magnesium monitoring, while maintaining high stability and reproducibility.

The following application note details INFICON crystals for OLED deposition, the development process, and the experiments the company performed to characterize and evaluate the crystal quality to make sure it offers the highest possible solution for the OLED industry.

Background

Quartz crystal microbalance (QCM) is one of the most important INFICON products for organic light-emitting diode (OLED) and optical device fabrication, as well as for many other applications. The change in the QCM's resonance frequency due to mass loading by thin films allows it to be used as a surrogate for correlating the rate of the film thickness accumulation on a substrate. The design of INFICON High Precision Sensor Crystals was based upon many OLED manufacturers’ requirement of more stable crystals that are less prone to activity dips (instability in the activity signal) in controlling the deposition of OLED materials. The field performances of INFICON High Precision Sensor Crystals have shown to improve rate stability with nearly extinguished activity dips in terms of the number of occurrences as well as the magnitude when they rarely occur. Refer to the “High Precision Sensor Crystal Line Technical Note” found using this link.

Samsung to use a single-stack structure in its first 8-Gen OLED production line

Last Month Samsung Display confirmed that Samsung is now building a 8-Gen (2200x2500 mm) OLED production line, that will begin production in 2024.

It is expected that the new line will mostly produce panels for IT devices (laptops and tablest) and also for automotive applications. Many believe that these applications will adopt tandem stack structure to increase brightness and lifetime. According to a new report, Samsung's new line will adopt a single-stack structure, and not a dual-stack one.

Samsung to increase its QD-OLED production capacity by year's end, will introduce 77-inch and 49-inch panels

Samsung Display says that it managed to increase its QD-OLED production yields to around 85% (up from 75% in April). The company plans to introduce new technologies and processes that will enable it to increase its production capacity from 30,000 monthly substrates to almost 40,000 at the same production line.

Samsung Display will so increase its QD-OLED production capacity by 30%. The main step to achieve this is the reduction of TAKT time (the time it takes to produce one panel).

Samsung Display's CEO confirms plans for a 8-Gen IT OLED production line, to begin operations in 2024

Samsung Display's CEO Choi Joo-sun says that the company sees a great potential for OLED displays in the IT market (mainly notebook and monitor displays), and that Samsung is building a new 8-Gen (2200x2500 mm) which will begin production in 2024. The glass efficiency at 8-Gen (uncut glass) will be 20% higher compared to Samsung's 6-Gen lines.

This new fab was already reported last year, but this is the first time we officially hear a commitment from SDC. According to DSCC, there are over 10 8.5-Gen OLED lines under consideration now in the industry, as demand for OLED panels for laptops, tablets and monitors is o the rise. Samsung is the current leader in OLED IT displays.

LG Display and SK Hynix to collaborate on OLED microdisplay production

According to a report from Korea, LG Display and SK Hynix has agreed to collaborate on OLED microdisplay development and production. The two companies are at the final stage of negotiations.

If this goes through, SK Hynix will produce the backplane silicon wafers, while LG Display will handle the OLED frontplane deposition and encapsulation.

BOE says its OLED production in Sichuan is limited due to power rationing, but no major impact

As Sichuan province in China suffers from a record heat wave, and the local authorities announces power rationing, limiting power supply to factories in the area.

BOE has two 6-Gen OLED production lines in Sichuan (the B7 line in Chengdu which started operation in 2017, and the line in Mianyang). The company says that it will have to "make adjustments" to its operations in both lines, but it does not expect any major impact on its operations.
