As we look at the global economic growth rates for 2022, one country’s GDP performance stands out: Vietnam. According to the International Monetary Fund (IMF), Vietnam’s estimated GDP growth rate for 2022 is 7%, compared to 2.6% in 2021, making it the most fast-growing country among the neighbouring countries.

Undoubtedly, the country’s impressive performance is largely due to the global supply chain’s migration to the country, driven by the COVID-19 pandemic and the trade war between the US and China.

Pandemic and Trade War as Catalysts for Supply Chain Relocation

Long before the supply chain’s recent move, Samsung had already made aggressive investments by allocating 60% of Samsung Galaxy phones’ production in Vietnam. As a result of that, Vietnam’s electronics manufacturing exports surpassed its largest industry, textiles, a decade ago.

Over the last couple of years, the increasing tension between U.S. and China’s lockdown during the pandemic has made the leading brands aware of the high geopolitical risks as well as the importance of supply chain diversification. These concerns forced them to vigorously re-evaluate the plan to move their manufacturing factories to Vietnam, mitigating the risks they are exposed to.

Laptops: The Last Piece of Puzzle

In this migration, Apple and Dell have been the most proactive brands. After Shanghai’s lockdown, Apple has chosen Vietnam as its second-largest production base for laptops, tablets, and TWS earphones. Luxshare has already attracted attentions for building an AirPod production line in Vietnam, but not until recently, the laptop OEMs in Taiwan have geared up for expanding their investments there: a couple days ago Quanta Computer just announced a $50 million investment to establish a Vietnamese subsidiary to produce MacBooks; Foxconn, another key supplier of Apple’s macbook, is reported to begin their trial run for macbook after an $9 billion investment in 2022 for capacity increase.

On the other hand, it is said that Dell had actively reviewed its suppliers and component sources before 2022 to ensure the stable supply for their bidding market in the North American. As Dell becomes more aggressive in shifting their production lines from China to other locations, suppliers such as Compal and Wistron have also been actively building laptop assembly lines in Vietnam for the past two years.

A flexible production model is on the horizon

In the past, most OEMs considered Vietnam as a backup due to the complex logistic management potentially caused by the relocation of production lines. However, given that the most complicated and rigid laptop supply chains have begun to move, it is generally believed that this represents a solid trend where Vietnam is almost set to take over China’s position.

According to TrendForce, Vietnam is projected to account for 5% of global laptop shipments by 2023, which marks a notable increase from less than 1% just a year ago, making the country the second-largest laptop production base after China.

However, from the perspective of supply chain risk diversification, brand customers demand production models that not only reduce over-concentration in China but also enable quick response to possible contingencies at each production base.

That means even if laptop production is concentrated in China and Vietnam, if there is an urgent situation, OEM factories’ production lines in other regions must be able to provide immediate support. Such production models will inevitably reshape the supply chain landscape moving forward.

According to a recent report by TrendForce, automotive applications are expected to become the main growth driver of the CIS market, with its share of terminal applications projected to increase from around 9% in 2023 to approximately 15% in 2026.

As self-driving systems become more widespread, the demand for CIS in the automotive industry will continue to increase. Trendforce estimates that the average number of CIS used per car will increase from 3-4 in 2022 to 6-7 in 2026, with the overall market size growing from $1.8 billion in 2023 to over $3 billion in 2026 at a CAGR of over 20%.

On the other hand, due to the stagnation in the number of camera modules, the growth of the smartphone CIS market is expected to be in the low single digits. By 2026, CIS terminal applications in smartphones are predicted to decrease from 63% in 2023 to 51%, while automotive applications are projected to increase from 9% to 15%.

The report offers the following insights into the CIS market for smartphones:

• 10.5% decline in smartphone production in 2022: Due to factors such as war, pandemics, inflation, and inventory adjustments, global smartphone production in 2022 declined by 10.5% to 1.193 billion units, resulting in a 6.7% decline in the shipment of camera modules to 4.46 billion units and a 4% decline in the overall CIS market size to $18.9 billion.
• 5% growth in the CIS market size in 2023: The report predicts that the global smartphone production will increase by 0.9% to 1.203 billion units in 2023, with the shipment of camera modules reaching 4.62 billion units, up 3.6% YoY, driving the overall CIS market size to grow by 5% to $19.8 billion.
• Stagnation in the number of smartphone camera modules: From 2021 onwards, the proportion of shipments of smartphones with four and more rear camera modules has remained at 21%, slightly lower than the 23% in 2020, and is expected to remain at the same level in 2023.
• The trend towards large size and high-resolution CIS: In 2021, Samsung launched the world’s first 200-megapixel CIS, the ISOCELL HP1, while Sony introduced the IMX989 in 2022, marking the official entry of high-end smartphones into the one-inch era.

Additionally, driven by new features such as night photography, it is anticipated that the image quality of smartphone cameras may surpass that of single-lens reflex cameras (SLR) by 2024, resulting in the increase of market size and ASP of CIS.

The latest study by TrendForce shows that demand for large-size and mobile driver ICs will steadily grow as various applications recover. However, the speed of capacity supply adjustment and competition among different technologies will remain the key focus in the next few quarters.

Another thing worth noting is that the US chip ban has led to a trend of independent development between Chinese and non-Chinese supply chains. While this may increase production time and cost, it also presents opportunities for individual Chinese domestic suppliers and Taiwanese wafer foundries to acquire fresh orders.

Observations by TrendForce on each sector of driver ICs are summarized below-

• Large-size panel driver ICs: demand is expected to recover gradually and stabilize prices, but suppliers are cautious about inventory, which could lead to a supply shortage if demand surges too quickly.
• TDDI for mobile devices: prices and inventory have reached a low point, with a small rebound expected. In the long run, AMOLED panels are expected to dominate, so IC suppliers will need to explore new applications for medium-sized panels.
• AMOLED driver ICs: UMC’s 28nm high-voltage process is producing AMOLED driver ICs. If Apple shifts all 40nm AMOLED driver IC production to 28nm, TSMC’s 28nm capacity availability will be crucial to the market’s supply-demand balance.
• RAM-Less AMOLED driver ICs: RAM-Less AMOLED driver ICs with Chinese flexible AMOLED panels are gradually taking shape due to China’s domestic policy. However, the rapid price drop of Full-Ram AMOLED has caused brands to hesitate on adopting Ram-Less AMOLED.

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.
