It looks like the under-screen fingerprint sensor technology will become a new fad after Qualcomm announced the second generation of the 3D sonic sensor, which worked to provide an excellent development over the first generation, in terms of size and speed of response.
The second generation covers a larger area than the previous one, to allow it to be touched more easily, and its response is higher than the first generation, which makes its using experience better.
This new generation comes with an area of 8 * 8mm compared to 4 * 9mm previously, so there is a 77% increase in size to receive the fingerprint with greater precision. The company says the response has also been sped up by around 50%.
Qualcomm launched the first generation of the under-display fingerprint sensor two years ago with optical scanner technology, and it was common in the more prominent smartphones that use this type of fingerprint, but today, with ultrasound technology, it has become better and faster.
The fingerprint sensors under the old screen encountered many issues, especially security, as they opened when touched by a finger other than the registered finger when there were protective stickers on it. ‘screen.
We are expected to see new smartphones using the Qualcomm sensor developed starting next month, and we may see it in the Samsung Galaxy S21, which will be announced after each day, especially as the company Korean used Qualcomm sensors under the display in its previous S and Note flagship phones.
