Not long ago, we just reported that Samsung may use its own offline fingerprint identification technology system on the S10 series mobile phones. Surprisingly, the latest patent document released by the U.S. Trademark and Patent Office shows that Samsung is not satisfied with the fingerprint identification system under the local screen. They are studying a new technology to make the full screen fingerprint unlocking function of mobile phones possible.

It is reported that this technology will allow users to unlock fingerprints in any area of the screen, which is easier to use than the current local screen fingerprint identification system. The principle of this technology is to build a biometric sensor inside the screen, so that the whole screen of the mobile phone can participate in the scanning of fingerprint identification. In addition, Samsung will also use a low-power processor under this screen to collect and process fingerprint sensor information, so as to ensure efficient and accurate fingerprint identification process. It is worth mentioning that this fingerprint system supports dirty hand unlocking. When your fingers touch the screen, the screen will quickly and automatically adjust the screen brightness for three consecutive times before scanning the fingerprint. Therefore, even if your fingers have dirt or water stains on the surface, the scanning information of the sensor will not be affected.

According to the patent description, this technology will be used in other categories of products such as smart home products in addition to mobile phone products. Although this technology is still on paper, it is unknown when Samsung will launch products with this technology. But if Samsung can really implement this technology and put it into commercial use, it is believed that it will have a significant impact on the entire consumer electronics market. After all, all mobile phones equipped with offline fingerprint identification systems, such as OPPO Find X and vivo NEX, can only unlock fingerprints in the designated fingerprint identification area, and the accuracy and speed of fingerprint unlocking are not ideal.
