Apple’s latest AirPods 3 still feature an optical in-ear detection mechanism, according to TrendForce’s 2021 Infrared Sensing Market Trend - 3D Sensing, LiDAR, SWIR LED report. Through the integration of PPG (photoplethysmography) technology, the AirPods 3 contain an improved in-ear detection mechanism based on skin-detect sensors that are equipped with four SWIR (short-wave infrared) LED chips that have two different wavelengths, as well as two InGaAs photodiodes. Industry insiders indicate that the AirPods 3’s skin-detect sensors may potentially detect the water content in the wearer’s skin, giving them the ability to differentiate between human skin and other surfaces. TrendForce expects annual AirPods shipment for 2022 to reach 85 million sets, a 3.7% YoY increase.
Escalating trade tensions between the US and China, rising geopolitical issues, increased tariffs, and uncertainties stemming from the COVID-19 pandemic’s emergence last year have compelled server ODMs to actively shift their operations closer to clients as well as engage in risk mitigation strategies, according to TrendForce’s latest investigations. Taiwanese ODMs, in particular, are shifting their production bases away from domestic China and accelerating the installation of additional overseas production lines. TrendForce expects the share of servers manufactured in domestic China by global server ODMs to undergo a 7% YoY decrease this year as these ODMs shift their production bases mainly to Taiwan. Furthermore, Taiwanese ODMs are expected to account for about 90% of total server production this year.
DRAM contract prices are likely to exit a bullish period that lasted three quarters and be on the downswing in 4Q21 at a QoQ decline of 3-8%, according to TrendForce’s latest investigations. This decline can be attributed to not only the declining procurement activities of DRAM buyers going forward, but also the drop in DRAM spot prices ahead of contract prices. While the buying and selling sides attempt to gain the advantage in future transactions, the DRAM market’s movement in 2022 will primarily be determined by suppliers’ capacity expansion strategies in conjunction with potential growths in demand. The capacity expansion plans of the three largest DRAM suppliers (Samsung, SK hynix, and Micron) for 2022 are expected to remain conservative, resulting in a 17.9% growth in total DRAM bit supply next year. On the demand side, inventory levels at the moment are relatively high. Hence, DRAM bit demand is expected to grow by 16.3% next year and lag behind bit supply growth. TrendForce therefore forecasts a shift in the DRAM market next year from shortage to surplus.
Demand for fast chargers used for various consumer electronics has been quickly rising. For instance, smartphone brands such as Xiaomi, OPPO, and Vivo led the industry by releasing fast chargers in 2018, subsequently gaining consumer acceptance via their fast chargers’ competitive advantages in cooling efficiency and compact physical dimensions. At the moment, notebook computer manufacturers are also expressing a willingness to adopt fast charging technology. Hence, the GaN power devices segment became the fastest-growing category in the third-generation semiconductor industry. TrendForce expects annual GaN power devices revenue for 2021 to reach US$83 million, an impressive 73% YoY increase.
Display panels contain certain semiconductor parts, including driver ICs, TCONs, and LCD PMICs; the price trends of these ICs used in different applications depend on their respective supply and demand situations. Not only has demand for driver ICs used for TVs, Chromebooks, and consumer IT displays declined ahead of other applications, but panel suppliers have also accumulated a considerable inventory of driver ICs for these aforementioned products, according to TrendForce’s latest investigations. Hence, these driver ICs may see their prices stagnate in 4Q21. Nevertheless, although driver IC suppliers will not be able to offload the foundry costs for driver IC manufacturing to panel suppliers entirely, panel suppliers are still expected to procure additional driver ICs in order to avoid possible shortages, since demand for commercial IT displays and driver ICs used in these displays still exists. TrendForce therefore expects driver IC prices to experience a minor price hike in 4Q21.
