IHS says that smartphone makers are expected to increase their adoption of under-the-display fingerprint sensors. In 2018, 9 million such smartphones will be sold, but the market will grow extremely quickly and will reach over 100 million unit in 2019. By 2022, over 300 million such phones will ship.
Under-the-display sensors are currently only applicable to OLED displays. Chinese phones makers (such as Vivo and Huawei) already started shipping the first phones to adopt this technology. IHS estimates that looking forward, the market will be led by Samsung and Chinese smartphone makers such as Vivo, Huawei and Xiaomi.
