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.

According to TrendForce research, after smartphone panel shipments peaked at 1.95 billion in 2018, overall shipments declined gradually year over year. After 2020, due to the impact of the COVID-19 pandemic, shipments fell sharply to 1.796 billion units. In 2021, as the pandemic festered along with serious shortages of components overall, downstream customers continued to raise inventories to allay possible risks of shortages, driving the scale of panel shipment upwards again to 1.888 billion units. Looking forward in 2022, as mobile phone shipments are expected to remain flat, overall smartphone panel shipments have the opportunity to maintain a similar level to that in 2021, reaching approximately 1.872 billion units, a decline of only approximately 0.9%.

Judging from the shipment scale of major panel makers, BOE has become the global leader in smartphone panel shipments and it has an opportunity to maintain a scale of 502 million panels in 2022. SDC ranks second and it is expected to grow to the level of 479 million units in 2022, of which all shipments are AMOLED panels. Third to fifth consist of Tianma Microelectronics, Innolux, and TCL. From the perspective of the previous five manufacturers, the three major panel manufacturers in China alone contributed approximately 52.1% of global smartphone panel shipments, meaning that China has become an important hub for the production of mobile phone-related components and assembly, followed by South Korea panel companies at 28.5%, Taiwanese panel companies at 10.5%, and Japanese panel companies at 8.9%.

The proportion of AMOLED panels is still growing in the mobile phone panel market. As a-Si LCD panels fulfill demand for the low-end entry-level market and LTPS LCD panels nestle between the two, the market is becoming increasingly crowded. From the perspective of AMOLED technology trends, in response to changes in mobile phone specifications, AMOLED is currently developing in the direction of power conservation and folding. Therefore, technologies such as LTPO backplane and COE form the key development directions of several major panel manufacturers at this stage. Excluding SDC , which maintains certain leading advantages and is the benchmark for other panel manufacturers, panel specification requirements required by brands such as Apple for the iPhone will also have a significant impact on the development direction of AMOLED panel specifications. At present, China’s production capacity is mainly based on flexible AMOLED panels, while SDC has invested resources in both rigid AMOLED and flexible AMOLED panels. According to the overall AMOLED panel shipment plan for 2022, shipment scale is expected to be approximately 703 million units, or 15.4% YoY.

In the past, LTPS panels were produced predominantly by Japanese panel manufacturers. In the early days, due to these companies’ close partnership with Apple, LTPS panels were primarily used in mid-to-high-end smartphone models, which also led to a wave of LTPS LCD production line expansion. However, as the technology matured, coupled with the successive rise of Chinese panel plants and the growth of Chinese mobile phone brands, the primary panel manufacturers in the overall LTPS LCD supply have gradually switched from Japanese to Chinese panel companies and prices and costs have also continued to improve and decline. Overall LTPS LCD panel factory shipments are forecast to reach approximately 494 million units in 2022, a YoY decline of 10.7%.

a-Si LCD panels were an important foundation in the development of the entire smartphone panel market. However, with the rise of LTPS LCD and the subsequent increase in AMOLED panel production capacity, a-Si panels have gradually retreated to the low-end entry-level mobile phone market. a-Si LCD is mainly based on the HD resolution and the bulk of supply still comes from Chinese panel manufacturers, of which BOE is the main panel supplier. It is worth mentioning, due to fierce competition in the low-end mobile phone panel market, most Japanese and Korean panel manufacturers have successively reduced their supply of a-Si panels. Among Taiwanese panel manufacturers, AUO has also continued to reduce the supply of its a-Si panels. Shipments of a-Si LCD panels in 2022 is forecast at approximately 675 million units, a decline of 7.0% YoY.

(TechNews) Google confirmed on May 4th that it has acquired Raxium, a start-up company with Micro LED display technology, which is expected to become key in Google’s mission to create a new generation of AR displays.

Google senior vice president of devices and services, Rick Osterloh, who leads the development of Google’s hardware products, stated that Raxium has spent five years creating a small, cost-effective, and energy-efficient high-resolution display that lays the foundation for future display technologies, adding, this company’s technology in this field could play a key role in Google’s hardware investments. Raxium, headquartered in Fremont, California, will be merged into Google’s devices and services group in the future but he did not disclose the purchase price or other details.

According to Raxium’s official website, the pixel pitch of s Super AMOLED screen on a mobile phone is approximately 50 microns but the company’s Micro LED technology can achieve approximately 3.5 microns and it claims to be able to create unprecedented display efficiency.

When foreign media, The Information, reported last month and first exposed Google’s plan to acquire Raxium, it pointed out that Micro LED technology can create AR displays that are more energy-efficient than other solutions while retaining vivid colors. In addition, Raxium is working on the monolithic integration of Micro LEDs, which is expected to significantly reduce costs.

This move makes Google’s plans for subsequent AR hardware products increasingly clear. Google acquired glasses startup North in 2020 and is reportedly recruiting engineers to develop an operating system for AR displays. It was revealed by foreign media in January this year that Google’s laboratory is developing a head-mounted AR device code-named “Project Iris” which is under the same management as “Project Starline” shown at the Google I/O 2021 developer conference last year.

Thanks to the increased adoption of AMOLED panels by major smartphone brands including Apple and Samsung, the penetration rate of AMOLED panels in the smartphone market is expected to reach 39.8% in 2021 and 45% in 2022, according to TrendForce’s latest investigations. As AMOLED panels see increased adoption, the consumption of AMOLED DDI will undergo a corresponding increase as well. However, not only are the process technologies used for AMOLED DDI manufacturing currently in short supply, but some foundries are also yet to finalize their schedules for expanding their AMOLED DDI production capacities. Given the lack of sufficient production capacity, the increase in AMOLED panel shipment may potentially be constrained next year.

Regarding process technologies, the physical dimension of AMOLED DDI chips is generally larger compared to other chips, meaning each wafer yields relatively fewer AMOLED DDI chips, and more wafer inputs are therefore needed for their production. The vast majority of AMOLED DDI is currently manufactured with the 40nm and 28nm medium-voltage (8V) process technologies. In particular, as 40nm capacity across the foundry industry is in tighter supply compared to 28nm capacity, and TSMC, Samsung, UMC, and GlobalFoundries are the only foundries capable of mass producing AMOLED DDI, an increasing number of new wafer starts for AMOLED DDI are being migrated to the 28nm node instead.

Regarding wafer supply, the foundry industry is currently unable to fulfill client demand for 12-inch wafers. Hence, 12-inch capacities allocated to AMOLED DDI production are relatively limited as well. At the moment, only TSMC, Samsung, and UMC are able to allocate relatively adequate wafer capacities, although their capacity expansion efforts are still falling short of growing market demand. In addition, while SMIC, HLMC, and Nexchip are developing their respective AMOLED DDI process technologies, they have yet to confirm any mass production schedules. TrendForce therefore expects that the additional AMOLED DDI capacities to be installed next year will remain scarce, in turn further limiting the potential growth of the AMOLED panel market.

AMOLED DDI suppliers must overcome the issues of limited production capacity and technological difficulties in R&D

Other than the issue of tight production capacities, the difficulty of AMOLED DDI development is further compounded by the fact that each panel manufacturer has its unique specifications of AMOLED panels. For instance, panel manufacturers differ in terms of their display image uniformity (including the calibration of on-screen picture quality via eliminating display clouding, poor color/brightness compensation, and sandy mura). Hence, in order to address the discrepancies among panels manufactured by different companies, IC suppliers must adopt different compensating solutions and account for different parameters. Panel manufacturers therefore are likelier to adopt DDI from IC suppliers whose solutions have already been in mass production.

If prospective IC suppliers were to enter the AMOLED DDI market, they would need to overcome various difficulties in AMOLED DDI development, including long processes of validation and revision, in order to mass produce at scale. As well, each individual panel supplier requires its own different set of IP cores (referring to the various functional modules in an IC) and specifications, making it difficult to manufacture AMOLED DDI that is universally compatible with all AMOLED panels. For instance, ICs that are supplied to Korean panel manufacturers by AMOLED DDI suppliers are incompatible with AMOLED panels from Chinese panel manufacturers, which require new wafer starts with their own requirements.

On the whole, other than certain DDI suppliers which have their own subsidiary foundries or have longstanding foundry partners capable of DDI production, TrendForce believes that fabless AMOLED DDI suppliers must not only secure a stable and sufficient source of foundry capacity, but also possess sufficient technological competency for mass production, in order to successfully expand their presence in the AMOLED DDI market.

This year, the US and Europe, which are Apple’s main markets for iPhone devices, are seeing an easing of the pandemic and expecting an economic recovery. Furthermore, Apple is expected to benefit from Huawei’s abandonment of some market share for high-end smartphones, and the sales of the new iPhone devices in 2H21 will likely be boosted thanks to this development. On the whole, the outlook on Apple’s performance in the smartphone market for the whole year is positive, according to TrendForce’s latest investigations. Although the ongoing capacity crunch in the foundry industry will have a constraining effect on Apple in terms of ramping up its iPhone production and growing its market share in the future, TrendForce is still maintaining a cautiously optimistic view and forecasts that the annual total iPhone smartphone production for 2021 will grow by around 12.3% YoY to 223 million units, with additional room for a slight growth going forward.

Apple will prioritize the optimization of existing functions with the iPhone 12s series, while retail prices are expected to remain on par with last year’s release of iPhone 12 models

Apple plans to unveil the next generation of iPhones, tentatively called the iPhone 12s series (official name has yet to be revealed), in September 2021, and the smartphone market has placed the spotlight on the new handsets’ physical appearances as well as retail prices. Regarding the general outward appearance of the upcoming iPhone devices, the notch on top of the screen will shrink due to the decreased size of their sensor housings. Apart from this, other upgrades will mostly relate to the optimization of existing functions and features. All in all, the degree of innovation is not particularly significant in terms of appearance, and the four new models can be regarded as an extension to the iPhone 12 series. Because of this, TrendForce also believes that Apple will continue the proactive pricing strategy that it adopted in 2020 so as to maintain its market share for high-end smartphones. Even though prices of some key components have risen due to tightening supply, Apple is taking into account of the growth in the revenue of peripheral services in relation to the growth of iPhone sales. This means that the starting price of the upcoming iPhone series will likely be relatively on par with the starting price of the iPhone 12 series.

For the latest iPhone models, Apple has made certain upgrades to the handsets. TrendForce here summarizes the key components of the latest iPhone models, including the processor, display, memory, and camera. The iPhone 12s series will feature the A15 processors manufactured at TSMC’s 5nm+ node. Regarding the display, the new models will be equipped with flexible AMOLED panels with On-cell touchscreen technology; the two Pro models will also feature a 120Hz refresh rate. Judging by the iPhone 12s series’ starting prices as well as the differences among various models’ retail prices, TrendForce expects the new handsets’ memory capacities to remain the same as their iPhone 12 counterparts. On the camera front, Apple has upgraded all iPhone 12s handsets’ main cameras to include sensor-shift image stabilization technologies. For the Pro models, not only are their ultra-wide cameras now equipped with 6P lens (which is an upgrade over the previous generation), but they are also capable of autofocus functions. Notably, it should be pointed out that LiDAR scanners are available in the Pro models only.

On the whole, TrendForce expects the latest iPhone devices to account for about 39% of Apple’s total annual production volume for 2021. As all iPhone 12s handsets contain 5G modems, the share of 5G models in the overall iPhone production is projected to expand massively from 39% in 2020 to 75% in 2021. Furthermore, Apple is expected to focus on driving sales of the three non-mini models in the iPhone 12s series in view of the fact that the iPhone 12 mini (which reached End-of-Life ahead of time in 2Q21) suffered disappointing sales performances compared to other models in the iPhone 12 family.
