Face ID with fire infrared: Led manufacturers have to have diamond to do

Oct 31, 2017

As the industry becomes more and more competitive, the major handset manufacturers are looking for differentiation. As a barometer of smartphones, the lack of innovation in Apple's phones in recent years has also led to doubts about its leadership. However, Apple always brings us unexpected surprises. 

On September 13, Apple unveiled the iphone X, the most powerful flagship in its history, to commemorate the 10 anniversary of the launch of its first smartphone. One of Apple's most promising products, the most exciting black technology, is face ID facial recognition technology, replacing the previous Touch ID. There is no doubt that this will set off a new wave in the smartphone sector. 

Face ID without infrared technology 

With respect to traditional facial recognition technology, Apple face ID technology based on three-dimensional image recognition technology, and the use of active light irradiation system and special camera, the use of data collected to build a three-dimensional facial model, while solving the security and poor illumination in the environment successfully identified difficult problems.

Specific portrait capture processes include: The infrared light intensity of the face recognition is determined by the distance sensor and the light sensor feedback imaging system, and then the infrared light is transmitted to the face by the IR optical generator, and the scanning point is up to 30,000. Infrared camera captures the scanning point from the human face, The 3D image model of human face is constructed. 

In the process of recognition of infrared light played an important role in the Apple brand driven, infrared products will be in the next few years to show a rapid growth trend, for the related industry development is undoubtedly a positive news. As a representative enterprise in the Global semiconductor field, Osram began to invest in infra-red application development as early as 1972 years, and became the fastest growing business direction. Based on the continued cultivation in the field of optoelectronic semiconductors, Osram has become the global leader in infrared applications, with a complete product layout and strong research and development customization capabilities. Based on the prospects of the industry, Osram also announced in the infrared led further expansion of research and development personnel to deal with the next market outbreak. 

In addition to facial recognition applications, iris recognition, security monitoring, laser radar, health detection, 3D sensing and other fields, is also considered the future of the potential of infrared LED market. As an industry leader, Osram has been the first to achieve the layout, and constantly explore the new direction of infrared LED applications. 

Infrared semiconductor components usher in a burst period 

Last year, Samsung Note7 's iris-recognition technology also caused a small response at the time. By using infrared LED matching iris recognition technology, the use of the human eye to emit infrared light, and then in a special environment can also be recognized. To this end, Samsung deliberately increased the amount of infrared led orders. Because the Apple face ID technology for hardware and software coordination requirements, domestic manufacturers are expected to take the lead in iris recognition technology, including Huawei and Millet in the next flagship machine will carry the iris identification technology. Thus, iris recognition technology will become the next "standard" function of smartphones.

According to relevant data, the 2020 global biometric market is expected to reach 25 billion U.S. dollars, of which the iris recognition technology will reach 3.5 billion U.S. dollars, its annual composite growth rate of 36.6%, will be in the smart phones, tablets and other consumer terminal market to achieve a wide range of applications. As early as in 2015, Osram launched the Oslux SFH 4780S light-emitting Diode is the first in the use of smartphones, mainly for iris scanning, for infrared products in the use of consumer terminals in the early exploration and technology accumulation. Its compact and high power characteristics, but also for the development of the industry set a new standard, and to obtain the same year, "Kaiser Friedrich Research Award." 

In addition, as the cost of infrared sensors gradually reduced, more and more wear equipment began to carry infrared sensors for heart rate, blood sugar and other physiological parameters of detection, and this will become the future of wearing equipment, one of the important trends, the behind is also inseparable from the infrared LED technology. For example, Osram's newest SFH7060 sensor can be used to measure pulse rate and blood oxygen saturation. The health level can be continuously detected by integrating in the wearable equipment. 

Osram SFH7060 Sensor 

SFH7060 consists of three green LEDs, a red light led, an infrared LED and a large photodiode, which is optically isolated from the transmitter through an opaque optical bezel. Its working principle is light irradiation to the skin, blood and the surrounding tissue will be absorbed by the different amount of lights, the absorption of light is reflected back to the detector. The pulse rate and oxygen saturation can be determined using measured values measured at different wavelengths. 

In addition to the consumer market, self-driving cars are becoming the next tuyere of global concern. The main principle is to use the LIDAR sensor to build the 3D model around the environment, detect and perceive the relative movement of the surrounding objects and cars, and then feedback the car to realize the auxiliary or automatic driving. Among them, the LIDAR sensor is mainly based on the Fast Infrared Pulse laser diode, which captures the distance between the object and the automobile. Osram provides laser diode for the world's first automotive laser sensor. Recently, Osram Strategic purchase of Canadian Laser Radar company Leddar Tech 25.1% of the shares, further strengthen its in the auto driving area of the layout. 

With the rise of the consumer terminal market, the demand for infrared LED products will be opened quickly, bringing a new round of growth opportunities for the industrial chain. According to relevant data, the 2022 infrared light source market is expected to grow to 1.55 billion U.S. dollars. In this drive, the relevant enterprises began to focus on the layout. 

IR LED market pattern and challenge 

The infrared LED has warmed up since 2015, based on the outbreak of emerging application markets. The Asia-Pacific region is expected to become the world's largest market for infrared LED applications because of the constant infiltration of smartphones, security monitoring and automobiles.

The infrared LED is undoubtedly the new world compared to the visible light led market that has already killed the blood. To this end, into the field of infrared led manufacturers surged, according to statistics has reached more than 40. Unlike LED lighting applications, infrared LED manufacturing requires the use of four-yuan grain machine equipment, and more attention to the LED components of light design and customization. For the general manufacturers, still have a certain technical threshold. Although the number of manufacturers to enter, but the real strength to meet the development of new applications of enterprises or a few. 

At present, the global infrared LED manufacturers have Osram, crystal Yuan photoelectric, billion photoelectron, light huihong technology, light lei technology and other manufacturers. Mainly in Taiwan, the main manufacturers, compared to the mainland, the layout of a little later, such as the combination of photoelectric, Hong Li photoelectric and so on. The Taiwanese manufacturers have gradually reduced their advantages in general lighting and turned to the development of subdivision applications earlier. In the field of infrared led, already has a certain scale advantage, but in the market expansion and new technology import or less international manufacturers. Mainland manufacturers due to technical bottlenecks, the current cut into the manufacturers are relatively small, the formation of large-scale benefits for a period of time. In the field of infrared led, Osram and other few manufacturers are still in the leadership position. 

Osram as a global optoelectronic semiconductor representative enterprises, LED technology in the direction of industry development. In the infrared LED, Osram products can cover a variety of power output levels and packaging version, such as 760nm, 850nm, 940nm and other bands, can meet the needs of a variety of emerging applications market. In addition, osram in optical design, packaging technology, standardization, optical simulation, electrical simulation, industry synergy Development and other aspects of the leading edge, can provide downstream customization of the complete solution. Especially after the strategic transformation, Osram will be more focused on emerging markets, in the future will be in more areas to promote the development of LED technology, such as food testing, spectrum detection, communications and other applications. 


In the past two years, the infrared LED has been paid attention to, the IPhone x and Samsung Note7 natural work. Smartphone on the billion-level sales, for the infrared led outlines a bright future, which is also led manufacturers for the future expectations. For the rapid change of consumer terminals, led manufacturers must also remain vigilant and continue to deepen the product type to meet the changing application needs. 

Infrared LED market is on the eve of the outbreak, the future layout of enterprises need to have a clear understanding. On the one hand, the application of outbreak needs periodicity, on the other hand manufacturers enter the pace is accelerating. It can be foreseen that the infrared led market from the blue Sea to the Red Sea is also inevitable, just a matter of time. But that doesn't mean there is no chance, after all, the growth in the size of the IR LED market is also obvious. 

Overall, the rise and fall of general LED lighting Field tells us that the development of new applications is the future market growth. For the enterprise, in addition to maintaining the advantages in terms of capacity, but also need constant innovation and exploration, leading to the LED application market development, so as to have the first advantage to win the future, as Osram is doing.
