Vivo had previously partnered with Qualcomm to showcase an under-display fingerprint sensor meant for its future smartphones. OnePlus, which is also run by the same owner, is said to have customised Oppo's technology and brought Dash Charge that is touted to be faster than what on the LG V30, iPhone X, and Google Pixel 2.
Moorhead states that enabling in-display fingerprint sensors on smartphones so far has been a manufacturability issue.
In terms of the security, Moorhead has also clarified that Synaptics has built-in a separate encryption module to the Clear ID sensor while also allowing the hardware to interact with the phone's processor for authenticating the fingerprint. The information comes from Forbes contributor Patrick Moorhead who got to spend some time with a pre-production unit of the Vivo phone.
The company has actually begun production of the sensor, dubbed the "Clear ID in-display fingerprint scanner". "I pressed the right side button to wake, a fingerprint image illuminated at the bottom of the phone, I touched it, and it let me in". The Galaxy S8 and the Galaxy S8+ were supposed to ship with one once upon a time but because the technology needed some more work before going full commando Samsung reportedly ditched the idea and instead went for a fingerprint scanner on the back. "Synaptics' Clear ID fingerprint sensors are faster, more convenient, and more secure than alternative biometrics, and this optical technology represents a major innovation shift and opportunity for the smartphone market".
From the smartphone makers' point of view, it would solve a few problems for them, since the new normal of the infinity or full screen display becomes easier to provision on the front of their devices and the general sense is that the location of the fingerprint sensor in the rear panel was not quite a comfortable location for it. He also indirectly talked about the iPhone X, which relies on FaceID authentication. Supposedly twice as fast as Face ID, Clear ID reads the user's fingerprint from beneath the screen, all without interrupting anything displayed. With Clear ID, Synaptics is looking to offer an even more seamless solution. The company was ranked fifth in IDC's Q1 2017 report, as pointed out by The Verge.
