Taiwan firms entering IR LED biometrics market
24 November 2016 16:46 GMT

Taiwanese chip makers plan to capitalise on a boom in biometric sensors of devices by making the LED sensors needed for iris and face recognition.

Shipments are expected to start shipping in 2017,  industry sources told the DigiTimes.

Currently, IR LEDs are mainly used in security surveillance and sensing, and most models are wavelengths of 850nm and 940nm, the sources said. However, IR LEDs used in iris recognition use wavelength of 810nm, the sources noted.

Epistar has IR LED chips taking up over 10% of all AlGaInP chip output at present, and the proportion is expected to rise to 30% in 2018, the sources said. Epistar has supplied IR LED chips used in iris recognition to a few smartphone vendors, the sources indicated. Arima Optoelectronics has stepped into production of IR LED chips for iris recognition which are in the process of certification.

LED packaging service provider High Power Lighting holds the opinion that notebook or tablet vendors will adopt IR LEDs for iris recognition faster than smartphone vendors because the software algorithm and related certification are key to adoption, and Windows 10 strongly supports fingerprint, facial, voiceprint and iris recognition, making it easy for notebook or Windows-tablet vendors to support iris recognition without a large R&D effort.
