Motorola patents rollable smartphone display with dual fingerprint sensors

Motorola seems focused on its Razr series of foldable clamshell Android smartphones right now. However, the development of a device that might supplant them one day is still going on in the background. 

The Lenovo brand's latest rollable smartphone patent has a potentially strategic upgrade: dual fingerprint readers. They are placed so that there would be one on each side when the device is in an 'unrolled' mode, so that the user can reach the sensor from the front or back.

Motorola reasons that users will want to unlock the device even when its display is not extended, for possibly increased security and convenience.

The document (Managing consistent fingerprint-on-display (fod) location on a rollable device having multiple fod sensors) has been approved by the US Patents and Trademarks Office (USPTO) since November 5, 2024.

Then again, the potentially useful new IP does not put the real-life version of the Motorola Rizr any closer to launch.
