In-display fingerprint sensors are expected to break through into the mainstream in 2018, according to research from TrendForce.

The company said like manufacturers including Samsung, LG, OPPO, Xiaomi, Huawei are likely to incorporate this technology, bringing the global fingerprint sensor penetration rate in smartphones to 60 per cent.

TrendForce has predicted that fingerprint sensors will remain the first choice biometric technology for most Android phones in 2018. This is because other biometric authentication methods available – including facial and iris recognition – are not capable of completely replacing fingerprint sensors yet.

Synaptics recently released new in-display fingerprint sensing solutions for AMOLED panels. This is now being seen in the Vivo X20 Plus UD, which was released this week.

Speaking at the demonstration of the technology at the Consumer Electronics Show in Las Vegas earlier this month, Alex Feng, senior vice president of Vivo, said: “With our efforts in extensive consumer research and long-term R&D investment, Vivo is well positioned to pioneer the development of fingerprint scanning technology.

“We first presented a prototype of our fingerprint scanning solution at MWC Shanghai 2017 based on an ultrasonic sensor, and have remained committed to realizing our vision for future smartphones.”

It follows rumours that have circulated for years about major brands Apple and Samsung introducing the technology to their flagship devices. However, neither company has made use of it yet.

TrendForce pointed to Synaptics competitors working on their own versions of the technology. Goodix, for example, recently sent sample products to major mobile phone vendors for testing, while Qualcomm has cooperated with Vivo in developing ultrasonic fingerprint sensing in 2017.

Swedish biometric authentication solutions provider FPC also released its ultrasonic fingerprint sensing technology at the end of 2017. TrendForce said that the “active engagements of these companies indicate that in-display fingerprint sensing will bring about a new trend for smartphones”.
