Smartphone manufacturer OPPO has launched its 5G-capable Reno3 and Reno3 Pro smartphones that feature Goodix’s optical in-display fingerprint sensor for biometric authentication.

Goodix’s fingerprint sensor — embedded beneath the smartphone’s display — is ultra thin, which allows for more internal space for things like 5G antennas and larger batteries.

The trend of smartphone manufacturers moving toward in-display solutions for fingerprint and camera sensors is a rapidly growing one, with both Xiaomi and Huawei recently launching phones featuring the technology.

Just last month, Apple was awarded a patent that may point to a future version of the iPhone also having in-display technology, perhaps signalling the return of Touch ID, which was last seen in 2017’s iPhone 8 and 8 Plus, before the feature was phased out following the release of the iPhone X, which saw the debut of Face ID as the lone form of biometric authentication for iOS.

In addition to supplying the in-display fingerprint sensors for the Reno3 and Reno3 Pro, Goodix also provided its capacitive in-ear detection (IED) technology for OPPO’s Enco Free TWS (True Wireless Stereo) earphones.

Goodix’s IED technology allows wearers to interact with the wireless earphones using touch gestures, like swiping to adjust the volume or change between media, and long press to wake a voice assistant.

This is also not the first time that OPPO has release phones featuring Goddix’s in-display sensors, with the two companies having worked together this past October on the Reno Ace and the OPPO K5, both of which were launched exclusively in China.
