Fingerprint sensor, hidden antenna, and VR support expected to be applied on next-generation iphones
Many new inventions have been announced by Apple, but it is still unclear whether these changes will be applied in the next iPhone line or not?

Future Apple devices may provide a larger fingerprint recognition area under the display and improve mobile Wi-Fi reception by embedding a larger antenna.

Newly published patent application explains in detail these problems and proposed solutions.

In addition to allowing touchscreen displays, a related patent application also covers the use of radio frequency antennas under the display layer.

Signals required for Wi-Fi and cellular networks require the antenna to be exposed, so the antenna that takes up the entire screen area of the iPhone is better than the narrowband antenna on the side of the device.

In June 2019, Apple applied to "use a narrow field-of-view filter with angular focus to enhance the fingerprint sensor under the screen".

Apple has claimed in the patent that the fingerprint sensor and matcher is widely used as a reliable personal identification or verification technology.

Optical fingerprint sensors can be convenient for verification or authentication in electronic devices, especially mobile devices.

Crucially, if you want to rely on Touch ID, it has to be reliable and timely. This is especially a problem when the Touch-ID sensor needs to be small enough, such as on the old Home button.

Challenges faced by optical fingerprint sensors include consistency of performance over time, as the contact interface is not stable enough to match small areas.

On the other hand, the patent continues to use a complementary metal oxide semiconductor (CMOS) for large areas.

Apple says that separating different reflected light at different angles is another challenge, as having to use multiple light modes to separate the reflected light, which can result in long photo capture times ( seconds).

The solution seems to be to make the Touch-ID sensor larger, but not too big to be too expensive or take up too much space on the device. Hence, finding ways to place the sensor under the display can solve these problems.

Apple's proposal is a display consisting of a glowing layer, an optical layer, a layer of filters and a pixel image sensor. The patent application shows that at least one of the optical or filter classes can focus the light reflected FOV (field of view).

The core idea of this patent application is to complete an optical scan of the displayed image and fingerprints from different angles.

Another Apple patent application involves embedding a radio frequency antenna into a display. In this case, the display may integrate a combined transparent antenna and is concerned with how to embed the front radio module (RFEM) into the display.

Embedding an antenna in the display can create a larger signal-receiving area without losing display space, Apple says.

Additionally, Apple is also developing a system that can create mixed reality or virtual reality environments from flat video content, allowing users to navigate and explore in segments that could only be two-dimensional.

The US Patent and Trademark Office has just announced an Apple patent called "Compositing Methods and Devices, which practically reproduce flat video content".

This patent clearly identifies synthetic reality or SR as digitally generated objects and environments. SR is essentially a broad category, and Apple says it includes virtual reality, augmented reality, and mixed reality.

Users can participate in the SR experience on the device, whether it's handhelds like iPhone or iPad, or head-worn devices like the rumored Apple Glasses. They can interact with the SR environment through one or more senses, including sight, taste, smell and touch.

However, most patent content focuses on a system that can generate SR characters, objects, and environments from flat video content. In other words, it can turn a TV program into a VR environment that users can explore with the aforementioned devices.

Interestingly, Apple also points out that similar SR-generation systems can build interactive scenes based on audio and related content, including audiobooks, dramas, and pure audio content.

Apple files a large number of patent applications every week, but there is no guarantee that the technology described in it will enter the market.

Likewise, the patent application does not give any indication of when Apple will launch new products equipped with this technology and users will have to continue waiting to experience.
