In recent years, China’s scientific research institutions have carried out multi-sensor image fusion technology and intelligent inspection robot technology in the industrial field, using military, aerospace, high-end equipment manufacturing, robots, driverless cars, smart grids and other key industries. Bionic sensor technology, flexible design technology and other advanced technologies of optical sensors, and these studies have been gradually market-oriented.
Among them, the popularity of optical sensor devices in the automotive, industrial, medical and consumer electronics fields has become increasingly important and has become an important symbol of intelligent product design, especially smart phones, smart lighting, digital electronic products, and smart manufacturing in recent years. The development of the Internet of Things technology has promoted the continuous improvement of optical sensor technology.
Recently, the Electronic Information Department of the Ministry of Industry and Information Technology entrusted the relevant industry associations and organized the “China Optoelectronic Device Industry Technology Roadmap (2018-2022)” jointly prepared by key enterprises, research institutions, universities, industry experts, etc. The figure gives a detailed description of the development status and planning of light sensor products. It is not difficult to see from this roadmap that optical sensor parts have very important significance for the development of the application market such as the downstream Internet of things, smart mobile terminals, and intelligent manufacturing.
Global light sensor market is 183.6 billion yuan
According to the data from the China Electronic Component Industry Association Information Center, in 2016, the global optical sensor market reached 137 billion yuan. In recent years, under the impetus of smart cities, Internet of Things, smart mobile terminals, smart manufacturing, robotics, smart grids, petroleum and petrochemicals, new energy, and other downstream applications, China's optical sensor market has grown rapidly and has become a global market for optical sensors. major force. In 2016, China's optical sensor market reached 77.8 billion yuan, accounting for 57% of the global market. It is estimated that by 2022, the global optical sensor market will grow to 183.6 billion yuan, the compound growth rate will reach 5% from 2016 to 2022, and the Chinese optical sensor market will grow to 111 billion yuan, and the compound growth rate will reach 7% from 2016 to 2022. . Although the growth rate of China's optical sensor market is still considerable in the future, due to the low level of development of the sensor industry in China and the weak strength of local companies, it is still very difficult to obtain a share in the fast-growing market.
In the field of infrared sensors, there are already several large-scale production companies. The technical indicators of some products can meet the needs of the domestic market, but the high-end technology is still climbing. In the field of fiber-optic sensors, due to the investment of several large fiber optic cable manufacturers in China, the technological level has shown a trend of rapid growth. However, the types of fiber-optic sensors produced in China are still relatively small, and the company’s sales are mostly in the tens of millions to 100 million. Within the scope of the yuan, and many of the company's sales are costs that contain fiber-optic sensor monitoring solutions, the real income of optical fiber sensor services is even lower, and most of the domestic market is still occupied by foreign companies.
In the field of image sensors with the highest market share, at present, Chinese domestic companies can occupy more than 80% of the market in the domestic market of image sensors less than 2 million pixels, but in the field of high-pixel CMOS image sensors, the core of mobile phone cameras, Almost no view of the Chinese manufacturers.
At present, the global high-pixel CMOS image sensor for mobile phones is mainly occupied by a small number of manufacturers such as Sony of Japan, Highway Technology of the United States, and Samsung of South Korea. However, in 2016, a consortium consisting of CITIC Capital, Qingxin Huachuang and Jinshi Investment acquired US Howe Technology, which will greatly promote the development of China's image sensor technology. The situation of laser sensors, ambient light sensors, and ultraviolet sensors is similar. There are few companies engaged in R&D and production in China. The domestic market is divided up by foreign imports. In general, the current status of China's optical sensor industry is mainly due to the small scale, low product quality, and low market share, which is inconsistent with the booming optical sensor market in China. Foreign countries attach great importance to the development and use of sensor technology. Japanese industry and industry people even claim that "governance of sensory technology can dominate the new era." The development of sensors in China started later than foreign countries, coupled with restrictions on the level of national economic development and funding, resulting in backward technology and slow development. According to assessment by domestic experts, compared with Europe and the United States, China’s sensor technology is 10 years behind in the research and development and 15 years behind in production technology. Optical sensor is one of the main branches of the sensor industry, and is basically the same with the entire sensor industry.
At present, European, American and Japanese companies rely on high-end products to maintain their market advantages, and domestic companies carry out price competition with medium and low-end products. There are two main reasons for the formation of domestic and foreign technological gaps: First, foreign countries attach great importance to the study of functional materials; Second, foreign countries attach great importance to the continuous improvement of manufacturing processes. Domestic and foreign countries have different ways of developing their technologies. They usually use the United States as their representative for civilian use after civilian use, first to increase their popularity, and to follow the road of independent research and development. Japan's representativeness focuses on practicality and commercialization. Taking the path from introduction, digestion and imitation to improving the design innovation on its own, China is also the civilian industry after the military industry first, and it is popularized first. However, subject to the limitations of the overall technological level, independent innovation is still a long way to go.
Multifactor constrains the development of the industry
In the field of optical sensor industry, intellectual property has become the focus of competition among countries. In the past five years, the number of patents in emerging industries in the world, especially in the United States, Japan, and Korea, has increased sharply, and the growth rate of patent applications for inventions has accelerated significantly. This is the average growth rate of invention patent applications in traditional industries in the same period. 4 times, while domestic enterprises lack strategic intellectual property rights, the number of patents is limited, and the substantive characteristics of invention patents are not prominent. In order to grow and expand, domestic companies must attach great importance to intellectual property rights, intensify work on intellectual property rights, give full play to the role of the intellectual property system, and support the healthy, rapid, and sustainable development of strategic emerging industries.
The optical sensor industry involves many disciplines such as optics, optoelectronics, microelectronics, materials science, and even computer networks. It requires the convergence of upstream, middle, and downstream industrial chains, and the need to maintain both basic research and application development. Therefore, diverse talents are needed. In particular, it is a compound talent who understands both technology and management.
Optical sensor SMEs face unfair economic policies China's current economic policies are mainly based on the type of ownership and industry characteristics, rather than the root's competitive position. The National Bank’s preferential policies for bad debt reserves, capital structure optimization support funds, new loans, and new listing quotas are almost entirely tilted toward large companies. In addition, SMEs also bear a wide variety of fees and charges that are not covered by the various tax components. The conditions for government funding are high, and the private sector lacks real-world VCs. Policy funding is difficult to implement.
China's optical sensor industry development ideas and goals
The "Road Map" proposes that the industry needs to use "research and development of new materials, research and development of new technologies" as the core content of development. Comprehensive research by domestic and foreign experts shows that the overall development trend of sensors is: intelligence, miniaturization, multi-functionalization, etc. In order to realize the above-mentioned development trend, the optical sensor company must target the needs of the application market and focus on the invention or improvement of the product, the discovery of new materials, and the innovation of the production methods, ie the implementation of new processes, based on the model of “application and innovation”. Etc., Focusing on limited advantages resources, tracking international technology trends, cooperating with related large-scale and scientific research units, including basic theoretical research cooperation; Secondly, conducting technical cooperation with foreign advanced sensor companies through technology transfer, OEM, cooperative operation, joint ventures There are many ways to absorb advanced foreign technology, and once again use the internal development management system must be established to effectively stimulate and restrict R & D personnel; Finally, we must introduce advanced research and development tools to provide protection for R & D reliability.
The fundamental task of development is to develop and improve the quality of high-end products. It is well known that there is still a big gap between the domestic sensor industry and internationally renowned sensor companies. The difference is that there are differences between experimental samples and mass production, and basic technology and theoretical research are lagging behind. Equipment, fixtures are relatively backward, the appearance and packaging and other details on the gap. Due to the low technical threshold, domestic companies rely on the cost advantage to occupy the majority of the market share in the low-end optical sensor field; while the market share in the high-end optical sensor area is mainly occupied by companies in Europe, America, Japan and Taiwan, and the future As the demand of the downstream industry continues to increase, leading domestic companies will seize more market share by leveraging the cost advantages of Chinese companies.
The “extensive to sophisticated management upgrade” is a solid foundation for development. In today’s sensor industry in China, the price of sensors has reached the stage where “the price of sensors must be higher, and the share of wool is indisputable”. Enterprises must have benefits and must pay more attention to management. In terms of refined management, we have effectively changed our concepts, implemented our goals with great strength, optimized operational procedures, improved work efficiency, strictly controlled costs, established corporate standards, and improved the assessment system. Promoting refined management, promoting the development of photovoltaic companies to enter the new normal and sustained and stable development.
Taking “enlarge international cooperation and occupying the international market” as the ultimate goal of development is the trend of the development of the sensor industry. If sensor companies want to remain invincible in the industry, they must take steps to expand their international cooperation and experience international markets. The baptism can eventually occupy the international market. The first is the introduction and management of international talents. Secondly, the sensors must pass international relevant certification before they can obtain the international market pass. The third is the construction of international marketing roads. Finally, quality assurance and customer needs are put first, and they are constantly growing in the international competition.
Industrial restructuring objectives
By 2022, the total sales scale of local brands in China's optical sensor industry has been greatly increased, the localization rate has reached more than 30%, and the product categories are basically complete. The product performance and grades are close to the level of international advanced enterprises in the same period. The cutting-edge products can meet the needs of China’s military industry. , aerospace and other fields. Focusing on the infrared sensors and optical fiber sensors with a relatively good industrial foundation, we will promote the strategy of large companies. By 2022, we will train 1 or 2 infrared sensors or optical fiber sensors with annual sales of more than 300 million yuan. The technical performance of the products will basically meet the needs of the domestic market. Local company. Focusing on the categories of miniature photosensors such as image sensors, ambient light sensors, facial recognition infrared sensors, and photoelectric heart rate sensors, which are used in mobile intelligent terminals, the adoption of absorption methods will increase the level of product technology and speed up the cultivation of national brands. In 2020, one or two Chinese national brands will cultivate innovative sensor-based SMEs and start-ups under the conditions of policy support and management, remove obstacles to innovation that are not conducive to innovation, and improve the start-up and development of innovative enterprises. The management framework will guide financial institutions to increase their investment in innovative companies. The rapid development of optical sensor products for R&D and industrialization has been accelerated through the investment in national-level industrialization support funds such as strong foundation projects and integrated circuit development funds.
