Infrared LED market will be explosive growth

According to the Samsung Galaxy S8, Apple's new generation of iPhone will be equipped with iris recognition and 3D Sensing and other optical sensing technology, will stimulate the infrared LED market A new wave of explosive growth. According to the latest "2017 Infrared LED / Infrared Laser and Sensing Component Application Market Report" issued by the agency, the market size of infrared LED and IR laser components in the iris and face recognition applications will reach $ 145 million by 2025 Will reach $ 827 million, 2017 to 2025 compound growth rate as high as 24%.

LED Yingide research vice president Wu Yingjie said that smart phones into the iris recognition, 3D Sensing technology and other new features, will make infrared LED, infrared laser and optical sensing related manufacturers benefit.

At present, the infrared LED market is widely used in the mobile phone and vehicle market, including safety monitoring, iris / face recognition, heartbeat oxygen detection, time of flight, Structured Light, Technology, automatic driving support system and so on. In recent years, hand-held applications such as smart phones, and gradually combined with identity authentication and payment system, more emphasis on user security, so the biometric function requirements more stringent.

Wu Yingjie said that iris recognition system has the advantage of high security, can find about 2000 different feature points, and fingerprints of about 100 feature points compared to the higher accuracy. Samsung Galaxy S8's iris recognition solution, which combines the near infrared camera (700 to 900 nm near infrared LED + image sensing lens), camera control technology and biometric technology. When the user to watch the screen, the phone's infrared LED lights will flash, and then photographed by the infrared camera iris lines to identify the identity.

On the other hand, because the infrared laser can be more accurately sensed, including distance sensing, auto focus, gesture sensing, noise reduction, etc., coupled with laser light focusing characteristics, but also help to reduce the aperture of the phone, so In the handheld applications, infrared laser will also have the opportunity to gradually replace the infrared LED part of the market applications.

Wu Yingjie pointed out that the infrared laser with 3D image sensing lens, the use of time to flight (Time of Flight) concept and structure of light technology to improve the three-dimensional (3D) measurement system precision, can create more accurate than 2D image image imaging.
