Under-display fingerprint sensors coming to a smartphone near you
This is because it allows displays to occupy almost all the area of the smartphone, something that the makers think users like. As a result the market for these sensors will grow strongly for the next three years led by Samsung and Chinese smartphone brands such as Vivo, Huawei and Xiaomi.
Phones using under-display fingerprint sensors, including the Vivo X20 and X21 and the Huawei Mate RS, were launched in late March. More are expected to come to market in 2H18.
Apple introduced fingerprint biometric identification on a dedicated Touch-ID button in 2013 followed by Android in 2015. Fingerprint recognition was applied to more than 60 percent of total smartphone shipments in 2017.
If Samsung applies under-display fingerprint sensor to the Galaxy Note 9, shipments of smartphones with the solution will hike to more than 20 million units in 2018, from the currently estimated 9 million units, IHS Markit predicts.
Sensor makers include: Synaptics, Goodix, Qualcomm and Egis, followed by Samsung LSI, FingerPrint Card (FPC), VkanSee, CrucialTec, BeyondEyes and FocalTech. Among panel makers, Samsung Display — with mature active-matrix organic light-emitting diode (AMOLED) panel manufacturing technology — takes the leading role as the under-display fingerprint can be only applied to AMOLED for now, followed by BOE.
