In 2021, notebook panel shipments reached a record high of 282 million units, with an annual growth rate of 25.1%, according to TrendForce’s research. In the first half of the year, demand was driven by the pandemic and primarily focused on consumer notebooks and Chromebooks while, in the second half of the year, as Europe and the United States gradually lifted lockdowns and work returned to normal, demand largely shifted to commercial models, which continued to support the demand for notebook panels throughout the year.

It is worth noting that TrendForce believes shipment totals of notebook panels from 1Q22 to 2Q22 may be corrected. Notebook panel shipments in 1Q22 are estimated at approximately 67.9 million units, a QoQ decline of 9.7% while 2Q22 shipments are expected to drop to 61.4 million units, down 9.5% QoQ. In addition to the impact of the traditional off-season, there are two reasons for this correction. One is that inventory on the brand-side has increased. Due to the shortage of panels in the past two years, the brand-side continued to purchase panels in 2021 to avoid supply chain disruption. Normally, notebook brands hold 4 to 8 weeks of inventory but some brands have already stocked up to 8 weeks. Two, since a whole notebook requires numerous components, it cannot be assembled and shipped if even one is missing. Limitations impose by incomplete materials lists caused the growth rate of notebook computer shipments to fall behind that of panel shipments, shifting notebook computer panels into oversupply.

Despite this, TrendForce has specifically mentioned, since the profit margin of notebook panels still beats LCD monitor panels and TV panels, panel makers will still desire an increase in the supply of notebook panels. However, in the face of a possible correction in notebook panel shipments, panel makers may accumulate more inventory and deepen the downward pressure on notebook panel pricing.

Looking forward to 2022, panel shipment performance and price trends will be adversely affected by adjustments in notebook brand inventories in 1H22. In 2H22, notebook brands will continue to focus on sales plans for whole notebook computers. The sales performance of these brands during the peak season is still worth looking forward to and the restocking momentum of notebook panels is expected to recover. Current estimates put the shipment of notebook panels at 265 million in 2022, a decrease of 6.0% YoY.

From 2020 to 2025, the compound annual growth rate (CAGR) of 12-inch equivalent wafer capacity at the world’s top ten foundries will be approximately 10% with the majority of these companies focusing on 12-inch capacity expansion, which will see a CAGR of approximately 13.2%, according to TrendForce’s research. In terms of 8-inch wafers, due to factors such as difficult to obtain equipment and whether capacity expansion is cost-effective, most fabs can only expand production slightly by means of capacity optimization, equating to a CAGR of only 3.3%. In terms of demand, the products primarily derived from 8-inch wafers, PMIC and Power Discrete, are driven by demand for electric vehicles, 5G smartphones, and servers. Stocking momentum has not fallen off, resulting in a serious shortage of 8-inch wafer production capacity that has festered since 2H19. Therefore, in order to mitigate competition for 8-inch capacity, a trend of shifting certain products to 12-inch production has gradually emerged. However, if shortages in overall 8-inch capacity is to be effectively alleviated, it is still necessary to wait for a large number of mainstream products to migrate to 12-inch production. The timeframe for this migration is estimated to be close to 2H23 into 2024.

PMIC and Audio Codec gradually transferred to 12-inch production, alleviating shortage of 8-inch production capacity

At present, mainstream products produced using 8-inch wafers include large-sized panel Driver IC, CIS, MCU, PMIC, Power Discrete (including MOSFET, IGBT), Fingerprint, Touch IC, and Audio Codec. Among them, there are plans to gradually migrate Audio Codec and some more severely backordered PMICs to the 12-inch process.

In terms of PMICs, other than certain PMICs used in Apple iPhones already manufactured at 12-inch 55nm, most mainstream PMIC processes are still at 8-inch 0.18-0.11μm. Burdened with the long-term supply shortage, IC design companies including Mediatek, Qualcomm, and Richtek have successively planned to transfer some PMICs to 12-inch 90/55nm production. However, since product process conversion requires time-consuming development and verification and total current production capacity of the 90/55nm BCD process is limited, short term relief to 8-inch production capacity remains small. Effective relief is expected in 2024 when large swathes of mainstream products migrate to 12-inch production.

In terms of Audio Codec, Audio Codecs for laptops are primarily manufactured on 8-inch wafers, and Realtek is the main supplier. In the 1H21, the squeeze on capacity delayed lead times which affected notebook computers shipments. Although the stocking efforts of certain tier1 customers proceeded smoothly in the second half of the year, these products remained difficult to obtain for some small and medium-sized customers. At present, Realtek has partnered with Semiconductor Manufacturing International Corporation (SMIC) to transfer the process development of laptop Audio Codecs from 8-inch to 12-inch 55nm. Mass production is forecast for mid-2022 and is expected to improve Audio Codec supply.

In addition to PMIC/Power Discrete, another mainstream product derived from 8-inch manufacturers is the large-sized panel Driver IC. Although most fabs still manufacture 8-inch wafers, Nexchip provides a 12-inch 0.11-0.15μm process technology used to produce large-sized Driver ICs. As production capacity at Nexchip grows rapidly, the supply of this product has been quite smooth. However, TrendForce believes that this is a special case. Mainstream large-sized Driver ICs are still manufactured on 8-inch wafers and there is no trend to switch to 12-inch wafers.

According to TrendForce research, since reaching a peak of 1.457 billion units in 2017, it has been difficult for smartphones to significantly increase their penetration rate. In addition, mobile phone hardware updates have slowed which has lengthened the consumer replacement cycle. Add to this the negative effects of the COVID-19 pandemic and growth in overall smartphone shipment volume has become increasingly difficult to achieve. However, based on the premise that the pandemic is slowing down, coupled with the strategy of certain brands actively exploring emerging markets, growth momentum in the global smartphone market has gradually gotten back on track in 2021, with shipments reaching 1.333 billion units, or 6.4% growth YoY. This upward trend is expected to continue in 2022, with shipments expected to reach 1.386 billion, or 4% growth YoY.

TrendForce emphasizes, it should be noted that the status of the pandemic is still the biggest concern affecting the smartphone market this year and this applies doubly to the production capacity of semiconductors. The current problem of material shortages has yet to be alleviated and RF chips, OLED DDICs, and PMICs continue to be in short supply. In addition, issues such as China’s rolling blackouts, spiking shipping costs, and rising chip costs, will cause smartphone brands to face price pressures and it remains to be seen whether higher prices will be acceptable to consumers.

Judging from the 2022 brand market share forecast, Samsung will remain number one followed by Apple, Xiaomi, OPPO, VIVO, and Transsion. Among these companies, Xiaomi is the brand with the fastest-growing annual shipment growth rate. In addition to stimulating sales in the Chinese market through the strategy of expanding brick and mortar stores, Xiaomi’s sales occur mostly overseas, and it is first in market share in India and Russia. In the future, it will continue to explore the Middle East, Latin America, Southeast Asia, and Africa markets.

Four keys to mobile phone trends in 2022

Folding phones, 5G, self-developed chips, and a reduction in the number of rear-facing cameras are the four keys to focus on this year. In terms of 5G mobile phones, the global penetration rate in 2021 was 37%, this is expected to rise to 47% in 2022, and may exceed 50% by 2023. At present, China is the most active country in promoting 5G models. More than 80% of the country’s shipments are 5G mobile phones. Therefore, the key to increasing the global penetration rate of 5G mobile phones in the future is focusing on regions outside China.

Regarding self-developed chips, in the past, only Samsung, Apple, and Huawei were capable of self-developing chips. However, Google launched its self-developed Tensor processor in 2021, and Xiaomi, OPPO, and VIVO have each launched professional imaging chips in succession.

According to GSMARENA (1/20), Apple may unveil the new iPhone SE, christened the iPhone SE+ 5G, sometime between late April and early May. According to what is currently known, this model will be a continuation of the previous generation design wise but whether it will employ a 4.7-inch LCD screen with a Touch ID button is unknown. The only thing known for certain is that it will be able to connect to 5G.

The SE models launched in 2020 utilized the A13 chip and a 4G Modem (the same configuration as the iPhone 11) and, according to rumors, the new SE will adopt the A15 chip and a Qualcomm Snapdragon X60 modem, (like the iPhone 13). TrendForce believes, as the release of the affordable iPhone SE (third generation) is imminent in 1H22, it has entered small batch production. The plan to supply in April is roughly on schedule and the first batch of mass production is expected to be 4 million to 5 million units. Although this new model is distinguished in neither appearance and nor specifications, as the most affordable of Apple’s 5G mobile phones, paired with brand premiums, it is still expected to occupy a place in a market where large-sized panels are king, More than 20 million units of this single model will ship throughout the year. （Image credit: Pixabay）

In recent years, the biggest trend of smartphone camera modules is the increasing number of rear camera modules, according to TrendForce’s investigations. According to TrendForce research, triple camera modules surpassed dual camera modules to become mainstream in 2020 and drove the continued growth of smartphone camera module shipments. Annual smartphone camera module shipments in 2022 are expected to reach 4.92 billion units, or 2% growth YoY.

However, the trend towards multiple cameras started to shift in 2H21 after a few years of positive growth. The previous spike in the penetration rate of four camera modules was primarily incited by mid-range smart phone models in 2H20 when mobile phone brands sought to market their products through promoting more and more cameras. However, as consumers realized that the macro and depth camera usually featured on the third and fourth cameras were used less frequently and improvements in overall photo quality limited, the demand for four camera modules gradually subsided and mobile phone brands returned to fulfilling the actual needs of consumers. In addition, increases in the pricing of semiconductor chips such as PMICs and Driver ICs, as well as increased shipping costs, have driven the cost of mobile phones up sharply. Without the ability to effectively pass this cost onto consumers, any remaining allowance to economically install low-end cameras has been effectively eliminated.

Camera resolution upgrades: fastest growing market share encompasses 49-64 million pixel cameras

Although camera shipment growth has slowed, camera resolution continues to improve. Taking primary cameras as an example, the current mainstream design is 13-48 million pixels, accounting for more than 50% of cameras in 2021. In second place are products featuring 49-64 million pixels which accounted for more than 20% of cameras last year with penetration rate expected to increase to 23% in 2022. The third highest portion is 12 million pixel products, currently dominated by the iPhone and Samsung’s flagship series. However, a 48 million pixel primary camera is expected to be introduced to the iPhone 14 Pro series (tentative name) that Apple will release this year, further reducing 12 million pixel products to a 15% share in 2022.

In addition to the original Samsung and Xiaomi brands employing 108 million pixels cameras, Vivo and Honor also introduced similar resolution cameras in 2021. There is a chance 200 million pixel products will be ready for commercial use in 2022, driving the penetration rate of ultra-high pixel products to an expected level in excess of 5% in 2022. However, such ultra-high pixel products primarily focus on enlarging photographs without losing image quality. Therefore, TrendForce believes that any marginal benefits these products bring to consumers will gradually decrease and the penetration rate will not grow as quickly as 49-64 million pixels products.

Overall, TrendForce believes that the number of camera modules mounted on smartphones will no longer be the main focus of mobile phone brands, as focus will return to the real needs of consumers. Therefore, triple camera modules will remain the mainstream design for the next 2~3 years.
