Widely used! The development of infrared LED in handheld devices Market

According to the TrendForce's green energy division LEDinside recently released 2015 second quarter of the global LED market analysis report shows that the application of infrared LED market is quite extensive, including image sensing, somatosensory / motion detection, light blocking sensors, proximity switches, position sensing, biological identification, pulse oximeter detection etc.. Future applications of infrared LED handheld applications, including information security and health management and its added value, profit space can be expected to drive the steady development of the infrared LED market.

LEDinside Research Assistant Manager Wu Yingjie said that the current applications of handheld devices, in addition to the application of LED in the 940nm wavelength infrared proximity switch function, to prevent accidental contact, reduce power consumption, finger vein identification, iris recognition function is gradually introduced into the infrared LED. The main infrared LED chip manufacturers, in addition to new Japan Radio Corporation, Japan EPITEX, Rohm semiconductor, Nichia, European manufacturers OSRAM semiconductor manufacturer Vishay, Taiwan, and crystal power plant, light and crystal photoelectric research hong.

In recent years, a number of handheld devices such as smart phones, combined with identity authentication and payment system, more emphasis on the user's security, and therefore more stringent requirements for biometric features. Iris recognition system is the most common biological identification and high safety, through iris identification, can find out about 2000 different feature points, compared with about 100 fingerprint feature points, the higher the accuracy. Iris recognition system with near infrared camera (700-900nm NIR LED +CCD), camera control technology and biometric technology, when users look at mobile phone screen, infrared LED lights will be flashing on the mobile phone, and then by the infrared camera to make use of iris texture, identity identification.

At present, iris recognition in airport, ATM, information security and identity security application increasing, since 2006 the Japanese Oki Electric Industry launched iris recognition mobile phone, after years of technology promotion, Fujitsu also launched the Arrows NX F-04G collocation function of the mobile phone in this year, other brand manufacturers are gradually for iris recognition is widely used in the patent. Consumer electronic products including notebook computer, mobile phone and Windows 10 tablet computer products, to create security demand opportunities. At present, the main iris recognition system manufacturers include Panasonic, Oki Electric industry, IrisGuard, EyeLock and IriTech.
