You can’t unlock your iPhone while wearing a mask!Apple has a new solution: fingerprints under the screen | duzline.com

Apple describes in the patent how to make this fingerprint recognition patent more reliable and feasible.

Most of the fingerprint scanning systems under the screen of Android mobile phones, use the light emitted by the display to illuminate the user’s fingertips.

This light is reflected from the fingerprint and back through the tiny openings between the pixels of the display.

Then, the sensor under the display can read the fingerprint and authenticate the user.

However, fingerprint recognition under the optical screen is prone to encounter the problems of low contrast and low signal-to-noise ratio, which makes it more difficult to read fingerprints and may increase the time for verifying user identity.

Apple’s fingerprint recognition system overcomes the problem of optical fingerprint recognition by capturing off-axis angular light from the finger through a series of “angle-dependent filtering options between the display and the sensor”.

Apple claims that this method can “improve the contrast of fingerprint imprints and maintain the size and compactness of the entire sensing system.”

Although Apple’s under-screen fingerprint recognition technology is still at the patent level, some analysts say that this patent may appear on the “iPhone 13” at the earliest.
