OLED is an emerging display technology that is fast becoming the mainstream display technology in many markets, as OLED enables display panels that offer the best image quality and free design as they can be made flexible and transparent. The Samsung OLED displays are considered to be the best in the industry and the Korean company is the clear lead in AMOLED production for mobile devices.

Over the pay years Samsung invested billions of dollars in OLED research and production facilities as the company sees OLEDs fast replacing LCD displays in all mobile applications.

Samsung AMOLED displays

Samsung is currently producing over 300 million AMOLED displays in a year, used mostly in smartphones - such as Samsung's own Galaxy S7 (and S7 edge ) - but also in smartphones from Gionee, Meizu, Acer, HP, Vivo, Microsoft, Lenovo, ZTE, Hisense, Konka and others. Samsung also produces large mobile OLEDs for tablets, laptops and monitors.

In August 2013 Samsung launched the company's first OLED TV, the KN55S9C, which used a curved 55" OLED panel. The TV was priced at around $8999 in the US and Korea, but is no longer in production, and was never in real mass production. Samsung has yet to return to OLED TV production.



Samsung flexible OLED displays

Following its initial flexible OLED production launch in 2013, and the huge success of its edge-type phones, Samsung is currently producing around 9 million flexible OLEDs each month to satisfy demand for the Galaxy S7 edge and its other flexible OLED products. Samsung has reportedly been chosen to supply 100 million flexible OLED panels to Apple's future iPhones.

Future Samsung OLED devices

Samsung is developing several next generation display technologies based on OLEDs. Samsung has been developing a foldable OLED device for a long time - which may dramatically change the mobile device market as it could enable smartphone to turn into tablets or phones that can be folded into smaller devices.

Samsung is also developing transparent OLEDs (see the company's 55" FHD transparent and mirror-type OLEDs here) for retail application, and also readies next generation displays for the automotive industry.

Several years ago Samsung released the following video, showing a concept transparent flexible AMOLED tablet device. It will be years before Samsung can commercialize such a display, but it's nice to see what the future holds:

Latest Samsung OLED news

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.

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.

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 aims to mass produce OLED microdisplays by 2024, full commeriability by 2026

Last month Samsung Display confirmed it is developing OLED microdisplays, and now the company provides more details on its plans.

Samsung admits it is still at an early stage of development, and it says it will start building its first line (with likely limited capacity) in 2023. By 2024 it will mass produce displays, and in 2025 it will expand capacity so that by 2026 it will achieve full commercialization.

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.

DSCC: OLED panels shipments declined 3% in Q2 2022, but revenues increased 12%

DSCC says that in Q2 2022, OLED panel revenues increased 12% compared to Q2 2021, while shipment units declined 3%. Fewer OLEDs were shipped, but revenues increased as we've seen an increased growth in high value panels (gaming, monitors, laptops, automotive, etc) and also an improved form factor adoption in smartphones.

OLED panel revenues and growth (2020Q2-2022Q2, DSCC)

In Q2 2022, smartphones remained the largest OLED application with a 76% unit and revenue share. OLED smartwatches had a 16% unit share (and a 6% revenue share), and OLED TVs had a 11% revenue share (up from 8% in Q1 2022).
