OLED is an emerging display technology that uses thin films of organic materials to make efficient, thin and high quality displays. OLED panels can made flexible, rollable and transparent. Korea's LG is at the forefront of OLED development and production - as the world's leading OLED TV producer and a leading developer of flexible OLED for smartphones, wearables, automotive and more. LG's subsidiary LG Display is responsible for OLED R&D and panel production, while LG Electronics produces and markets OLED TVs.
LG OLED TVs
LG Display is the world's leading OLED TV panel producer, and LG Electronics is its largest customer - although LGD also supplies OLED panels to other companies including including Panasonic, Sony, Philips, Loewe, JVC, Hisense, Konka and others. OLED TVs are considered the world's best TVs, offering the best image quality. LG makes a wide range of OLED TV panels, ranging from 42-inch to 97-inch, including bendable solutions and even a rollable 65" TV.
While the basic OLED TV design uses RGB OLED sub-pixels to create each 'pixel' (what is referred to as direct emission OLED, the design used in mobile OLED displays used in Samsung's and Apple's smartphones, for example), LG Display opted for a different OLED TV design. The so-called WRGB (or WOLED-CF) architecture uses four white OLED subpixels with color filters on top (hence W+RBG). The WRGB technology (developed by Kodak and now owned by LG Display) is much easier to produce and scale-up, even though it has some technical disadvantages - and it is the technology that enabled LG to be the first company to actually produce commercial OLED TV panels.
LG Flexible OLEDs
LG currently produces flexible OLEDs (branded as pOLEDs), for both wearable devices and smartphones. LG is the leading supplier of AMOLED displays for Apple's Watch smartwatch and it also supplies OLED displays for smartphones.

LG is also the world's leading automotive OLED producer, and is already supplying flexible OLEDs to Cadillac, Mercedes, and others.
LG Transparent OLEDs
LG has been working on transparent OLEDs for many years. In 2014 LGD unveiled a 18" transparent OLED prototype, and later in 2016 LGD demonstrated transparent 55" FHD AMOLED display prototypes. In 2019, the company started commercial production of 55" FHD transparent OLEDs, finding small markets in signage, commercial, mobility and more.

LG Display developed the world's first OLED gaming monitor panel with a switchable refresh rate and resolution
LG Display announced that it has developed world's first OLED gaming monitor panel with a switchable refresh rate and resolution. The company already mass producing this panel and will now aim to accelerate its market adoption and expects the first product to use this panel to arrive soon from LG Electronics, and other global gaming brands.
The new panel is 31.5" in size, and allows users to choose between two modes - high refresh rate more (480Hz and FHD) and high resolution mode (4K, 240Hz). The high refresh mode is aimed towards games in which speed is particularly important, such as first-person shooter (FPS) or racing games. The higher-resolution mode is more suitable for watching movies or 4K content.
Sony launches its 2024 TV lineup, with a mid-range OLED TV and a top-tier MiniLED backlit QLED
Sony announced its 2024 TV lineup, and interestingly, the top model (the Bravia 9) is a Mini-LED backlit QLED TV. The entry-level model (the Bravia 7) is also a QLED display, while the mid-range model, the Bravia 8, is based on LGD's WOLED panels.
The Bravia 8 offers 55-, 65- and 77 inch 4K WOLED panels, Sony's OLED Acoustic Surface Audio+ sound system, an upgraded XR Processor, and the creator calibration picture settings. Sony's 2024 TVs will launch in the summer of 2024.
LG Display to increase its WOLED panel shipments to Samsung, will reach almost 1 million units in 2024
According to a new report in Korea, LG Display aims to increase its OLED TV panel shipments to Samsung Electronics in 2024, and to reach almost 1 million units.
Samsung has recently signed a five-year OLED TV panel supply agreement with LG Display, as the two Korean companies are increasing their collaboration to fend off competition from China.
Will Samsung decide to abandon its QD-OLED technology?
In 2019 Samsung Display announced its decision to invest $10.85 billion in QD-OLED TV R&D and production lines. A few years later, SDC started to produce panels in its first fab, mass producing TV and monitor QD-OLEDs. The company attracted several customers (Sony and Samsung Electronics for TV panels, and several companies for its monitors), and these displays have been very well received by the market.
Since 2022, Samsung has increased its production yields, and increased its production capacity, and today it produces around 40,000 substrates a month in its 8.5-Gen production line. Reviews of QD-OLED gaming monitors and TVs are very positive, with many analysts seeing QD-OLED as improving over LGD's WOLED panels in terms of image quality.
But the reality at Samsung Display's QD-OLED division, is likely not so rosy. It seems that the technology is facing both market challenges and technology challenges - which may lead to a decision by Samsung to abandon it altogether.
Samsung Display increases focus on small and medium AMOLED production
A report from Korea suggests that SDC has transferred around 500 of its engineers from its large-area OLED development division, or about 30% of them, to its divisions that focus on small and medium-sized AMOLED development.
Samsung tri-folding AMOLED prototype
According to the report, the main reason for SDC's change of priorities is due to the need to remain competitive with Chinese-based OLED makers that are offering OLED panels at low costs. Samsung estimates that it is ahead of its Chinese competitors by only a year or a year and half, and it is just a matter of time until Chinese companies catch up with South Korea makers (SDC and LGD).
UBI: OLED tablet shipments to grow 7X in 2024, and continue to more than double by 2028
According to UBI Research, the OLED tablet panel market is set to grow quickly, more than doubling between 2024 (12 million units expected) to 2028 (28.4 million). That's a CAGR of 24.1%.
UBI says that the market in 2023 was only 1.8 million panels - so growth in 2024 will be dramatic (almost 7X), mostly thanks to Apple's adoption of OLEDs in some of its iPad modules (expected to be announced next month). Samsung will produce 11" panels for Apple, while LGD will produce larger 12.9" panels.
Omdia: Samsung leads the small and medium AMOLED market with a 43% market share in 2023
Omdia released its small and medium (9-inch and lower) AMOLED market share information for 2023, saying that even though Samsung's market share was lower than 50% for the first time, it stills leads the market by a large margin, with a 43% market share.
Samsung is followed by BOE (15%), LG Display (10%), Visionox (9%) and Tianma (8%). The total market reached 842 million units, a growth of 11% over 2022. Omdia says that the China-based OLED makers have been expanding their capacity and improving the quality of the produced panels, and are securing orders from domestic smartphone brands.

Seoul Metro installs more transparent OLED based AI translation services throughout the city
Towards the end of 2023, Seoul's Metropolitan Government has initiated a new pilot test at Myeong-dong Station that offers an AI-powered translation service for tourists that enables them to communicate with the subway staff through a transparent 55" LG OLED display.
The pilot was successful, and Seoul's Metro expanded the service to 11 stations, throughout Seoul. This is one of the first useful applications of transparent OLED displays, and it is great to see it expanded in Korea. We do not know whether there are any plans to roll out more such displays in Korea.
Samsung's upcoming S90D OLED TV lineup will feature displays utilizing both WOLED QD-OLED panels
According to reports from Korea, LG Display requested Samsung Electronics to use its WOLED panels on the same tier as SDC's QD-OLED panels, and Samsung will use both panel technologies in its S90D OLED TV series. Samsung will likely not disclose the actual panel technology to the consumer, and will likely decide on the panel technology per region.
The Samsung S90D will offer 42-, 48-, 55-, 65-, 77- and 83-inch panels. SDC only makes 55, 65, and 77-inch QD-OLED panels, and so in these sizes both QD-OLEDs and WOLEDs will be used. For the 42-, 48- and 83- models Samsung will only use WOLEDs.
