Samsung patents combined button and in-display fingerprint sensor
A patent for a combined home button and in-display fingerprint sensor filed by Samsung with WIPO has been published, LetsGoDigital reports.
The patent was originally filed in November, and describes a combined mechanical and slightly larger virtual button which includes a GUI, and could be used with a capacitive, optical, or ultrasonic fingerprint sensor. The virtual button could also be resized or its form changed by the user to enable different functions, and different actions such as a swipe could also be supported.
The design of the cover glass described in the patent includes several recesses, such as for a front camera, optical sensor, and receiver, and a screen-to-body ratio of 90 percent, significantly higher than the 84.2 percent of the Galaxy S9.
Analysts and industry watchers have speculated for months about if and when Samsung will launch a smartphone with an in-display fingerprint sensor. It was reported in May that both Apple and Samsung are working on ultrasonic in-display fingerprint sensors, and recent reports have indicated that the forthcoming Galaxy S10 will include in-display fingerprint capabilities.
