The latest “Automotive Display Market Analysis” from TrendForce indicates that the overall demand for automotive display panels (automotive panels) is gradually stabilizing and shows an upward trend as the automotive market as a whole slowly recovers, and promotional activities related to smart cockpits continue to expand. TrendForce estimates that the overall supply of automotive panels will maintain growth for 2023. Additionally, by 2026, TrendForce forecasts that the annual total supply of automotive panels will surpass 240 million pieces. Furthermore, as panel makers improve their OLED products in terms of performance and cost optimization, the market share of OLED in the market for automotive panels is forecasted to reach 8.9% by 2026.

The ongoing inflation has resulted in a significant decline in the demand for consumer electronics, prompting panel manufacturers to shift their focus towards automotive displays. Regarding the development of automotive panels, automobile manufacturers are now increasingly demanding greater integration in terms of design and functionality. This opens up new opportunities for panel makers to expand their presence downstream by offering system integration services. Panel makers aim to loosen the tight control that traditional Tier-1 automotive suppliers have over various automotive parts and components. Specifically, for displays used in cockpit systems, panel manufacturers are looking to establish a new kind of supply relationship with automobile manufacturers.

Automotive displays, including rear-seat entertainment screens, passenger-side displays, central information displays, and digital clusters, are evolving into more powerful communication mediums. Moreover, to integrate the various independent functions found in a traditional cockpit, larger screens and more flexible spatial designs are required. Hence, there is room for further advancements in various display technologies. For instance, pairing LCDs with a Mini LED backlight can significantly boost display brightness to over 1,000 nits, thereby improving display visibility when external conditions like snow and bright sunlight could cause interference. OLED panels, in contrast to traditional LCDs, offer notable advantages. They are self-emissive and thinner. They have a higher refresh rate and can be built on flexible substrates. These advantages can provide significant added value for automotive displays. Flexible OLED panels, in particular, allow for more innovations in vehicle design and are primarily positioned for flagship and high-end products in the automotive market.

In order to resolve the issue of durability for OLED among automotive applications, the technology is mostly adopted with Tandem OLED, which inter-concatenates and stacks multiple OLED components to form a high-efficiency OLED structure. Double-stacked OLED components require 1/2 less current density than that of single-layer variations after concatenation and are able to improve by a minimum of a twofold increase in lifespan under a much lower power consumption from panels. As for cost, Hybrid OLED panels are incorporated, where the assimilation between rigid OLED glass substrates and the thin-film packing technology used by flexible OLED would both reduce weight and cut cost, and curving effects can also be attained through thinned substrates.

TrendForce commented that a closer partnership between panel makers and automobile manufacturers is bound to be inevitable, should the former wish to expedite their market shares, seeing how automotive displays require approximately 2-3 years for testing and qualification. Subsequent to Samsung Display successively acquiring major orders from Ferrari and BMW, automotive leader LG Display has also announced to enhance its partnership with 9 luxury automotive brands by widening in incorporation of high-end automotive OLED panels, and is scheduled to mass produce its second-generation Tandem OLED, which has been vastly improved in brightness and power consumption. While LCD adopted with Mini LED BLU (Mini LED backlight technology) races to seize the automotive market through cost advantages, OLED is accelerating its entry into the high-end automotive display market by launching ultra-large, rollable, and transparent products.

As costs continue to decline, it is projected that OLED technology will reach a 50% penetration rate in the smartphone market by 2023. Additionally, OLED is gradually making inroads into applications such as TVs, laptops, and tablets. According to TrendForce analysis, the current landscape of OLED technology presents various opportunities and challenges depending on the application. In the realm of smartphones, the number of OLED smartphone products is on the rise, and the technology is taking on diverse forms, including rigid OLED screens, OLED curved displays, and OLED foldable displays.

TrendForce predicts that by 2023, the penetration rate of OLED foldable smartphones will reach 1.6%, with sales volume increasing from 12.8 million units in 2022 to 18.26 million units. With advancements in OLED display specifications and increasingly competitive pricing, OLED foldable smartphones are poised to become mainstream in the market. Currently, the penetration rate of OLED foldable smartphones is relatively low, primarily because OLED technology has not fully met user demands for larger screens within the same form factor while maintaining affordability. This marks a significant development trend for foldable smartphones in the future.

In response to the ever-evolving landscape of smartphone screens and high consumer demand, panel makers are taking a multi-faceted approach to upgrading OLED technology. To achieve full-screen displays while ensuring quality in screen visuals and camera functionality, certain brands have begun utilizing hole-punch screens, integrating the camera beneath the display – a prime example being the iPhone 14 Pro series with its Dynamic Island. On the other hand, companies like Samsung, BOE, and CSOT are opting to forego punch holes altogether. Instead, they are enhancing screen transparency and incorporating the camera beneath the display by rearranging specific display area pixels and reducing size.

Panel makers are enhancing OLED technology to improve both lifespan and efficiency. They are adopting LTPO technology to dynamically adjust screen refresh rates, reducing power consumption. Additionally, for foldable screens, companies are eliminating polarizers, using color filters to reduce reflection, and switching to ultra-thin glass cover panels. These optimizations are in response to the varied demands of smartphone applications, and they signal the continued growth of OLED in future smartphone uses.

In the realm of TV, TrendForce thinks that COVID-19, geopolitics, and rising shipping costs, furthermore, companies have been focusing on the development of larger-sized TVs, particularly in the 65, 77, and 85-inch categories, causing the overall decline in the TV market in recent years. The OLED TV market is primarily dominated by Korean manufacturers LG and Samsung. TrendForce projects that in 2023, OLED TVs will account for approximately 2% to 3% of the overall TV market.

TrendForce suggests that Samsung and LG are currently enhancing OLED technology by adopting new materials and incorporating quantum dot technology to improve OLED’s luminous efficiency. This has led to an increase in the cost of OLED technology, which in turn has limited the widespread adoption of OLED TVs. However, with factors such as depreciation of production machinery, improved yield rates for OLED products, and streamlining of the production process, it is expected that OLED TV prices will gradually decrease in the future.

Monitor

In 2023, OLED display shipments are expected to reach approximately 530,000 units, marking a 342% increase by YoY. However, OLED displays are projected to hold only a 2% to 3% market share in the overall display market. Within the OLED display market, LG is poised to surpass Dell and become the brand with the largest market share due to its proactive deployment of OLED product lines and diversified product offerings, along with strong demand for 27-inch products in the market.TrendForce states that the future of OLED displays lies in larger sizes, necessitating the use of higher-generation panel production lines for efficient and cost-effective OLED panel manufacturing.

Notebook, Tablet

In the laptop and tablet arena, as compared to smartphones and televisions, the application of OLED technology has been relatively limited. However, according to TrendForce, OLED technology is beginning to transition into IT-related applications. This includes innovations such as OLED Tandem device structures, as well as recent developments like JDI’s photolithography eLeap and Visionox’s ViP. These advancements are set to significantly enhance OLED performance and lifespan. When these technologies are ready for deployment, they are expected to effectively reduce OLED costs and substantially increase OLED panel penetration in the IT market.

Notably, Apple has already integrated OLED technology into its iPad products, and the Apple brand’s influence is expected to drive other brands to adopt OLED technology, accelerating OLED’s penetration in the IT market.

Automotive display

In the realm of automotive displays and other applications, TrendForce envisions a future for OLED technology characterized by transparency, extended lifespan, and versatility to meet the demands of foldable displays, automotive displays, and transparent displays. In automotive displays, OLED features such as high brightness, wide viewing angles, high contrast, and a broad operating temperature range make it suitable for applications like rear-seat entertainment systems and in-car infotainment displays. In the realm of transparent displays, OLED’s high transmittance and ability to display real-time information make it suitable for use in automotive windshields, windows, and A-pillars. Additionally, in the domain of stretchable displays, flexible OLED screens can be stretched and slid while maintaining a consistent thickness.

According to a report from Taiwan’s TechNews, despite running at a loss in the first half of the year, BOE believes that its target of shipping 120 million OLED panels still has a chance of being achieved. As the industry enters the traditional off-season in the fourth quarter, strict adherence to production capacity by panel manufacturers is expected to help stabilize panel pricing.

BOE mentioned that the price increases witnessed over the past few months were primarily driven by panel manufacturers, who maintained their bargaining power in price negotiations. This upward pricing trend continued into the third quarter. However, as the industry enters the off-season in the fourth quarter, some price fluctuations may occur. Nevertheless, panel manufacturers are expected to adjust their production capacity downward, making any potential price reductions manageable.

Furthermore, next year holds a brighter outlook for panel demand, with the average TV size projected to increase to 51.6 inches, compared to 50.2 inches in 2023, driving an 8% annual growth in TV demand for the coming year, compared to this year’s 3%. Replacement cycles are expected to contribute to overall demand for laptops and monitors next year.

In the first half of this year, BOE shipped approximately 50 million flexible OLED panels, marking a 76% year-on-year increase. The largest customer accounted for 43% of the total shipments. BOE believes there is still an opportunity to achieve the annual target of shipping 120 million panels. While the OLED business experienced an overall loss in the first half of this year due to increased capacity from second-tier suppliers and intensified entry-level competition, recent months have seen signs of a bottoming-out rebound in prices. Coupled with seasonal order increases, profitability is expected to continue to improve next year.

TrendForce’s latest report, “AMOLED Technology and Market Status”, reveals that OLED, the next generation of digital displays, has not only taken hold of the smartphone market but is also beginning to make its move into other applications. Organic OLED materials are the core of the industry supply chain, accounting for 23% of the cost of making smartphone panels. An increasing penetration rate has allowed the global value of OLED materials to be estimated at US$2.23 billion in 2022, with a YoY growth rate of 30%. Production values are expected to reach US$3 billion by 2025, owing to the support of manufacturers.

OLED light-emitting components are either based on polymers or small-molecule materials. Polymers have poor solubility in organic solvents, which results in impure color and poor film uniformity. However, when combined with printing technology, the high aperture ratio can fit more materials and compensate for the poor lifespan and efficiency of polymers. Small-molecule materials have purer color and exhibit higher brightness, which can be applied to larger-generation OLED production. However, they are currently limited to developing FMM and vapor deposition machines.

OLED production begins with synthesizing intermediates from raw monomers. Then, the intermediates are processed to become precursors before finally being sublimated and purified into terminal OLED materials. When raw monomers are synthesized chemically into intermediates, there’s a gross margin of about 10–20%. These are mainly supplied by Chinese manufacturing companies such as Jilin OLED Material, Ruilian New Materials, Aglaia Tech, and Shenzhen Mason. Terminal materials are produced via sublimation and purification and their structure will not change through subsequent production. Therefore, the chemical structure, processes, and formulas are essential to trade secrets for terminal material manufacturers. The purity of these materials after sublimation is expected to be very high, meaning that technological barriers are also very high, allowing for gross margins as high as 60–70%. The technology and patents are concentrated within a few foreign manufacturers. However, the booming market has led to an influx of upstream manufacturers, gradually breaking down past technological barriers. Some Chinese manufacturers have been able to achieve mass production of precursors and terminal materials, and are now actively competing in the supply chain and driving growth.

Apart from two electrodes, the structure of an OLED component consists of organic light-emitting materials, including the main host (light-emitting layer), guest material (dopant), and functional layers (with electron or hole transport properties). DuPont and LG Chemical are the major manufacturers of red OLEDs, while Samsung DSI and Merck mostly produce green OLEDs. UDC has a monopoly on red and green phosphorescent dopant materials due to patent barriers. Blue light-emitting materials used to be primarily supplied by Idemitsu Kosan and Merck. Recently, LG’s next generation OLED evo TV uses deuterium-based blue emitter materials—supplied by DuPont and LG Chemical—to improve blue light-emitting efficiency. Its precursors are supplied by Ruilian New Materials.

Besides established manufacturers like Tokuyama, Idemitsu Kosan, and LG, Chinese manufacturers are also beginning to enter into the market to supply functional layers, such as Laite’s Red Prime. Samsung and UDC are planning to commercialize blue phosphorescent materials in 2024 in order to address the lifetime issues of blue OLEDs. Many new technologies, such as South Korean materials manufacturer, Lordin’s, patented Zero Radius Intra-Molecular Energy Transfer (ZRIET) rely on the efficiency of energy transfer between the main host and dopant, which is highly dependent on the distance between them. When that distance approaches zero, the quantum efficiencies of the molecules will not be affected at all. Therefore, efficiency can be improved by controlling the speed of energy transfer between the internal molecules of the material. Lordin has synthesized a material that maintains the respective characteristics of the main and dopant materials as well as a high energy transfer rate, which is expected to produce OLEDs that will be four times more efficient.

TrendForce believes the next stage of mobile terminal products will shift from folding smartphones to smart wearables, IT, and automotive applications, which will place more stringent demand on OLED components. The layout of panel manufacturers is becoming clearer thanks to brand endorsements. LG, Samsung, and BOE are all aggressively competing for priority for the Tokki G8.7 evaporation machine to gain an advantage in expanding application. The accelerated commercialization of blue phosphorescent materials and more innovative technologies, such as Samsung’s vertical evaporation developed with ULVAC, eLeap lithography, and printing processes to improve the aperture ratio will help push the expansion of OLEDs in the display industry. Meanwhile, costs will become more competitive as more Chinese manufacturers enter the market.
