Samsung is yet to launch a flagship smartphone with an in-display fingerprint sensor, seen on flagship devices from Chinese smartphone makers. However, if a new patent filed by Samsung is anything to go by then the company is holding on to make the technology much better than one currently used by smartphone makers.

The details regarding Samsung’s plan to use in-display fingerprint sensor first appeared when the company filed patent for an optical fingerprint sensor on the screen. Now, details about another patent published on the same day has revealed that Samsung is already working on the future of such a technology. The first patent revealed Samsung’s implementation of the fingerprint reader on the screen similar to what we saw on flagship devices like the Vivo NEX and Huawei Mate 20 Pro.

This patent demonstrated that part of the screen will turn into fingerprint scanning area. However, the second patent describers a technology that seems much more advanced than the current generation of in-display fingerprint sensor technology. The patent reveals Samsung’s plan to use the full surface area of the screen as fingerprint scanner.

The patent also reveals that such a technology will be supported by a low-power independent processor. The processor is meant to increase the brightness of the screen as soon as contact of the finger is detected and will then scan the finger three times to ensure quality. The process sounds extensive compared to current bread of sensors but the challenge for Samsung would be ensure the whole action is rapid.

The patent also reveals that the new sensor, as described in the application, will be more accurate, easier to use and faster than current in-display fingerprint technology. The sensor has not only been designed for Samsung’s current flagship lineup but also for its future design with foldable display.

The patent application is accompanied by a rather intriguing image, revealing how the sensor technology could be incorporated into devices. The first device is a straight forward model with thick bezels around the display and seems reminiscent to that of Samsung Galaxy S3. The second device sports a notched display similar to that of Essential Phone and Huawei Mate 20.

There are already reports of Samsung having developed a new way to incorporate the front camera under the display. This is seen as a big technology breakthrough for developing smartphones with edge-to-edge display design without including a notch. It is not clear whether these new patented technologies will appear on the Galaxy S10 next year but Samsung could bring new features to mark a decade of the Galaxy S series.
