According to IDC's global quarterly smart home device tracker, the global smart home equipment market is expected to grow 31% year-on-year in 2018, reaching 644.9 million. The entire smart home market, including smart speakers, video entertainment products, connected lighting, smart thermostats and home monitoring/security products, is expected to have nearly 1.3 billion devices by 2022, with a compound annual growth rate of 20.8% over a five-year period. The fastest-growing category, with a compound annual growth rate of 39.1% in five years, nearly 100 million units in 2018, and 235 million units by 2022, will become smart speakers such as Amazon Echo and Google Home.
Jitesh Ubrani, senior research analyst at IDC Mobile, said: "Although dedicated smart speakers with built-in voice assistants will be popular throughout the forecast, we have seen significant changes in this market." "Many new devices inside and outside the home are now Includes built-in voice assistants. These devices not only help increase the number of touchpoints available to end users, but also help each assistant grow and gain insight into the content, time and manner of the user's various tasks by expanding coverage."
The privacy and security of smart home devices remains one of the key factors, as IDC's recent consumer Internet of Things. However, IDC remains optimistic about the market's prospects, as the convenience of smart home devices often exceeds concerns.
Adam Wright, senior research analyst at IDC Consumer IoT Program, said: "When considering the deployment of smart home devices, most consumers put security and privacy first." "In addition to having enough equipment to bring the device to market In addition to security solutions, vendors must respond to consumer concerns by appropriately educating them about privacy protections and increasing their awareness of the benefits of shared data, which can ultimately provide better data over time. Equipment and services."
Smart home equipment category highlights
Video entertainment products are mainly composed of smart TVs and digital media adapters, such as Google's Chromecast, Apple TV, Fire TV and Roku devices. As the center of the living room, this category is expected to grow. It is expected to reach 457.5 million units by 2022, with a five-year compound annual growth rate of 10.9%. For many brands and consumers, this category is expected to be the gateway to the smart home ecosystem, so IDC expects significant competition in terms of content and price in this category.
Home monitoring/security equipment, from door/window sensors to door locks and IP cameras, is expected to account for 19.4% of the smart home market by the end of 2022. Although this category faces great potential with a five-year growth rate of 27.3%, it is still targeted at a limited consumer base, especially homeowners, as most products still do not provide much value to consumers living in apartments.
Although smart speakers have become the focus of attention today, it will become the third largest category in 2022, as many vendors offer products that support Amazon Alexa or Google Assistant. Siri, Cortana and Bixby are also expected to build a wide range of usability, although none of these assistants will challenge Google or Amazon's position in terms of unit shipments. Although a large part of the market will not be able to run on these platforms, IDC expects that most of these smart speaker markets will flow to China, and established companies such as Xiaomi and Alibaba have already taken a large share.
Connecting lighting, thermostats and other products will complement the smart home market, providing users with a complete ecosystem of products and services to control and monitor their homes. The five-year compound annual growth rate for these categories is expected to reach 26.9%, while lighting products (such as Philips Hue) account for almost one-third of shipments. Although thermostats are popular in North America, they will face more growth in other parts of the world, as many countries do not use central HVAC systems and therefore do not require dedicated thermostats.

The research team of Xiamen University and Taiwan’s Hsinchu Jiaotong University (Guo Haozhong, Wu Tingzhu, Zhao Qingwei) recently developed a micro-LED surface brightness detection system based on microscopic imaging system, which can quickly measure the position of micro-LED array at any position during operation. Absolute brightness value.
LEDs have existed for more than half a century as an active self-illuminating device. Its low power consumption, low operating voltage, high illumination, long operating life and stable performance make it a very popular application. With the development of LED technology and the growing demand for micro-integration in various industries, micro-LED array devices have emerged. By further reducing the size of the LED chip, hundreds or thousands of micro-LEDs can be fabricated in the millimeter range to form a micro-LED array. micro-LEDs have potential applications in many areas, including micro-LED displays, high-speed parallel visible light communications, and high-voltage lighting chips.
In the display field, compared with LCD and OLED display technologies, micro-LED displays have the advantages of high luminous efficiency, high brightness, high contrast, and short response time. However, due to heat dissipation, aging and other problems, the imaging defects of the display affect the imaging quality, so the defect detection of the display is necessary. However, current measurement measurements remain at a macro level and cannot be used to accurately measure micro LED arrays, and the method used to evaluate the brightness of micro-LED arrays focuses on the measurement of total brightness, failing to quickly detect bad pixels in the micro LED array. . Therefore, it is very necessary to find a fast and accurate method to check the surface brightness of the micro-LED.

Recently, Intel and Ericsson implemented the first real-time data call conforming to 3GPP's new air interface (NR) 5G standard, using Intel RF millimeter wave chip and Ericsson radio system commercial equipment, including 5G NR radio AIR 5331, baseband and Intel? 5G mobile test platform. The 5G trial was demonstrated at the labs in Kista, Sweden and Santa Clara, Calif., and was the first multi-vendor data call on the 39 GHz spectrum.
The picture shows Intel's lab in Santa Clara, Calif., where engineers connect real-time data calls that comply with 3GPP's new airspace (NR) 5G standard to Ericsson Laboratories in Hitsta, Sweden.
Asha Keddy, vice president of Intel's Technology and Systems Architecture and Client Group and General Manager of Standards and Next Generation Technology, said: "The on-site 5G demonstration in the 39 GHz band marks the beginning of 5G commercial services in North America. With the Intel 5G mobile test platform with a 39 GHz RF chip/antenna, we successfully demonstrated a data call under the 3GPP standard for Ericsson's commercial 5G g-NB base station, an important step in ensuring that our commercial platform is ready for deployment in 2019. ".
The 39 GHz band is an important spectrum for commercial deployments beginning in North America in 2019, as all major operators plan to use this band. U.S. operators using a large number of 39 GHz millimeter waves will provide an ultra-fast experience based on 5G data rates. This is expected to drive a new era of communications and customer service. This latest achievement builds on Intel and Ericsson's earlier 3GPP NR standard calls on the 3.5 GHz frequency, indicating that the two companies are moving toward global interoperability across multiple frequency bands.
"The 39 GHz end-to-end data call with Intel shows our commitment to 5G in different frequency bands," said Fredrik Jejdling, executive vice president and head of network business at Ericsson. "In July we achieved interoperability at 3.5 GHz. Now at 39 GHz, these achievements will help our customers smoothly transition to 5G. This multi-vendor interoperability through commercial 5G radio marks a milestone in our 5G commercial implementation."
