An Apple patent covers under-screen iPhone biometric imaging for fingerprints, iris imaging, and facial recognition

Although there have been rumors that Apple has abandoned Touch ID under the display, Apple continues to work on its patented invention that not only covers Touch ID under the display. But also iris imaging and Face ID at the bottom of the screen. In April, Batley published an IP report titled “Apple wins patent to kill notch and put TrueDepth camera system behind screen so it doesn’t interfere with content.” Apple will need to implement today’s invention or a similar one to ensure Face ID can continue to work under the iPhone’s screen.

Apple’s invention includes a display and imaging sensor located behind the screen. Presentation is created from a number of structural and functional layers which are collectively referred to as the ‘presentation group’. The imaging sensor can be any suitable imaging sensor, including single-element imaging sensors (for example, photodiodes, phototransistors, photosensitive elements, etc.) and multi-element imaging sensors (for example, semiconductor arrays with complementary metal oxide, photodiode arrays, and soon). For convenient reference, imaging sensors – whatever they are constructed or implemented – are referred to here as “Optical Imaging Arrays”.

In many embodiments, An optical imaging array is placed behind a display screen and directed to receive the light transmitted through the screen in a direction generally opposite to that of the light emitted by the screen.

The optical imaging array may be used by the electronic device for any purpose suitable for imaging, sensing or data collection including, but not limited to: ambient light sensing; Proximity sensor Depth sensor Light receiving regulator Optical connection Proximity sensor Biometric imaging (for example, fingerprint imaging, iris imaging, facial recognition, etc.); and the like.

Apple patented FIG. 1A below depicts an electronic device that may have a display stack suitable for shooting across the screen; Figs. 1B depicts a simplified block diagram of the FIG electronic device. 1a; Figs. 6A depicts an electronic device comprising a display stack with increased local interpixel transmittance.

More specifically, Apple notes that it may be appreciated that regions of different pixel densities can be placed anywhere within the screen of an electronic device. For example, the FIG patent. 6A depicts an electronic device #600 that has a display stack defining an active display area #602 which in turn defines a high pixel density region #604 and a low pixel density region #606.

In this example, when the user of the electronic device touches the active display area #602 above the low pixel density area #606, the optical imaging array can image the user’s fingerprint. The user’s fingerprint can be photographed when the user’s finger is stationary or moving.

In some cases, the active display area #602 can display an image or animation that encourages the user to touch a specific part of the low pixel density area #606 so that the user’s fingerprint can be captured.

For example, on some models, the active display area can display a shape within the lower pixel density region #606. The shape may be animated in a way that catches the user’s attention. For example, a shape can pulsate, rotate in three dimensions, flash one or more colors, vibrate, etc. In other cases, other shapes, patterns, or animations can be used.
