From 445 million units in 2020 to 2016-2020, the total global shipment of smart wearable devices is 102 million units. It is expected that the compound annual growth rate from 2020 to 2025 will reach 25%, reaching 1.358 billion in 2025. department. The growth of shipments is inseparable from the diversification of product forms, and the products are accepted by consumers. From the original smart watches, smart bracelets, wearable headphones and other products, it is derived from smart rings, smart clothes, smart glasses, and even the universe and so on. An electronic enthusiast network editor Mo Tingting brought the theme of "wearable device industry development and market trend analysis", and analyzed the main chip, sensor, display screen, and operating system from four parts.

In terms of the main film, different chip solutions, BAS70SV has characteristics in the process, performance, integration, product positioning, etc., and can meet the smart watch products of different price points, different uses, and different network requirements. Stimulated by consumer market demand, mainstream chips will continue to grow in the future. The growth momentum mainly comes from three aspects: optimization of user base, product upgrade, and acceleration of medical-grade process. Facing the increasingly refined market demand, new requirements are put forward for the application requirements of the main control chip, which are mainly reflected in the aspects of low power consumption, integration, and multiple external interfaces.

As far as sensors are concerned, in the field of wearable devices, adult watches pay more attention to the use experience, such as battery life, scene integration, health monitoring, and children's watches, in addition to children's learning and social functions, due to the needs of parents, there will also be video and voice. Call, location and other functions. As far as the current development trend is concerned, both adult watches and children's watches have the trend of sports and health monitoring, among which the medical-grade process of adult watches is more obvious.

In order to achieve medical-grade development of wearable devices, cooperation in many aspects such as software and hardware manufacturers will be required in the future. At present, there are still pain points in development, mainly manifested in the difficulty of medical-grade certification, the large investment time, the need to improve the supply chain, the high technical requirements, and the difficulty in commercial implementation.

In the AMOLED industry, flexible AMOLED panels are gradually replacing liquid crystal panels and are being adopted by smart watch equipment manufacturers. The high screen ratio brought by AMOLED has also become the focus of attention of various manufacturers. The development trend of smart meter display is expounded from four aspects: first, miniaturization of display IC; second, new technologies such as integrated algorithms and millimeter-wave radar; third, panel upgrade and screen ratio improvement; fourth, high refresh rate and battery life .

According to Counterpoint Research, Apple WatchOS has a 21.8 percent market share among iPhone users. WearOS (WearOS+Fitbit+Tizen) has risen from 15.7% to 23.7%, becoming the second largest company after Apple WatchOS. But in China, with the rise of Xiaomi, Honor and other brands in the field of smart wear, it has also brought development space for the corresponding operating system. In addition, WearOS is driven by dual platforms. With the merger of Tizen.Fitbit and WearOS, the market position of WearOS will be greatly improved and become a strong competitor of Apple WatchOS.

In 2020, the semiconductor industry is also facing component shortages as it is less affected by chip shortages compared to consumer electronics markets such as smartphones and PCs. After research, it is found that in the electronic friend network, the main film and the sensor are the components with the most obvious impact of this shortage. Although the general environment is "out of stock", shipments of wearable device-related products will continue to grow and drive performance growth without reducing market demand.

At the end of her speech, Mo Tingting talked about the development trend of the wearable device industry in the future: First, the main chip, screen IC, display screen, operating system and other software and hardware will pay more and more attention to low-power design, and the pain point of mileage will gradually Second, the development of sensor technology will promote the improvement of the medical level of the wearable device industry, the third is the formation of a commercial closed loop; the third is the diversification of touch screen forms, which will bring new screens, millimeter-wave radar, laser modules, etc. Increasing demand; Fourth, the domestic mainstream operating system manufacturers will gradually rise in the future, and will present a three-legged, or colorful, colorful consumer market pattern; Fifth, in the consumer market with strong demand, domestic brands will gradually provoke the lead, and in the future, there will be opportunities to dominate Global Wearable Devices Market.

Qingwei Smart: High-efficiency reconfigurable chips bring a better experience to TWS headset users.

Zhao Junwei, director of Qingwei intelligent voice products, introduced the theme of "energy-efficient reconfigurable chips bring better experience to TWS headset users" in the sub-forum. "Qingwei Intelligence" is a company committed to becoming an international leading reconfigurable intelligent chip enterprise. Its core technology is a reconfigurable computing structure system, providing chip products and solutions for cloud computing.

In 2006, "Qingwei Intelligence" established a reconfigurable laboratory, conducted a lot of research on new structures, and after decades of accumulation, successfully passed the verification of reconfigurable chips. At present, the next products are image chips, voice chips, etc., which will reach 3 million within three years.

In the field of computer chips, most of the performance improvement comes from our Moore's Law, and in recent years, Moore's Law has also gradually slowed down. As the development speed of semiconductor process is getting slower and slower, it has reached the limit position, resulting in slower and slower speed of chip performance improvement. In order to improve the performance of the chip, we need to find a new architecture. This structure has both a CPU and an ASIC and a CPU, which is critical to improving the performance of the chip.

The traditional computing structure adopts an instruction-driven time-domain computing method. During the execution of the instruction, data processing and memory access are required frequently, and the high-frequency operation of the memory will consume too much of the chip. In fact, in traditional computing chips, nearly 80% of the system resources are used to store data or prepare for operations, and the calculation amount is only 20%, and the performance of the chip is not fully reflected. On this basis, using the reconfigurable computing structure, Qingwei Intelligent can make full use of system resources and achieve high efficiency.

In terms of voice signal, the reconfigurable transistor chip has 2-10 times the advantage of the traditional structure chip, and the high-efficiency signal processing efficiency reaches 6.13TOPS/W. At present, Qingwei Intelligent has released a reconfigurable computing engine voice chip integrating TX201 and TX231. According to Zhao Junwei, the audio sampling rate of these two chips reaches 768K, with active noise reduction and call noise reduction functions, which can achieve high-quality audio and are very suitable for TWS headsets, smart bracelets, headphones, Bluetooth speakers and other application scenarios.
