A Display ‘Window’ is Apple’s Unusual Solution to Hide its Selfie Camera
Apple has recently patented an unusual method for dealing with the much-maligned "notch" that contains its front-facing camera. Rather than use a system that places the camera under the display, Apple instead has designed a moving "window" that can open to reveal a camera behind it.
As noted by Patently Apple, the expandable display that scrolls open thanks to a motor hidden under the display is shown as hiding the camera area and notch when it is not in use. Apple describes it as a window region that overlaps on a movable portion of the display. When closed, the moving portion overlaps the window and the pixels in the moving display can act as if they were part of the complete display panel. When open, the moving portion is lifted away from the display so that the optical component can pass through without obstruction.
One image included with the patent shows a small cog located under the display that turns an arched, geared piece that is connected to a folding section of the display. When opened, the camera can peek through the opening and allow it to gain an unobstructed view.
The patent also describes a "rolling" display window that uses the same concept, but instead of relying on a hinge, the display is "rolled" back to reveal the camera.
Whether it is a hinged flap or a flexible roll, Apple seems to want to avoid having its cameras look directly through a display screen so that image quality can be its best.
As PetaPixel has covered in the past, multiple companies in the mobile space are working on a solution to the problem of the notch or hole-punch for a front-facing camera that will interrupt an otherwise edge-to-edge display. Under-display cameras appear to be the most popular choice, as both ZTE and Samsung have released consumer products that feature the tech.
Unfortunately, under-display cameras have their downsides. Because the camera is under a panel, the camera is physically encumbered by the pixels which can be visible in the image, especially in backlit conditions. Images also tend to be quite soft. Samsung's recently announced Galaxy Z Fold 3 does exhibit this issue, but it is strongly mitigated by heavy post-processing that seems to help fix the problem in several possible use cases, though it's still noticeable.
Both Xiaomi and Oppo have introduced solutions to this problem as well, and each claims to have solved the main issues with under-display technology. Xiaomi recently announced the Mix 4 which will feature the tech, and Oppo showed off its prototype solution as well. Both promise to be hugely improved over what Samsung and ZTE both have attempted.

Another issue with under-display cameras is that the pixels over the camera itself appear imperfect. Google has attempted its own design that will use a second OLED screen under the main screen along with a prism that it believes will help alleviate this issue.
Even though all these other companies have different methods for addressing the same situation, they all have one thing in common: few to no moving parts. Apple appears to be willing to risk the implementation of physical moving gear that directly bends the display, which is notable. Not only do moving parts mean more places that could break, but it also means that the device will take at least a bit of time to prepare itself to take a photo or video.
If Apple does ever use this patent, it likely won't be for some time. The Silicon Valley giant is known for playing the long game and being the last to add new technology into its devices. Under-display tech is still so new that Apple is unlikely to take a risk on anything unless it is far more proven, unlike Samsung, Xiaomi, or Oppo who enjoy positions as testers of bleeding-edge technology.

Android 12 Adds ‘Camera Switches’: Control Your Phone with Your Face
As part of the fourth Android 12 beta release which rolled out to Pixel phones last week, an updated version of Google's Android Accessibility Suite shows a way to interact with the device without using the touchscreen. Instead, it can leverage the front-facing camera to read expressions on a face.
As detailed by XDA Developers, Camera Switches is one of the options located in the Accessibility Suite that will allow users to interact with an Android device without using the touchscreen. Switch Access was previously available to allow for an external device -- like a keyboard or mouse -- to be connected either by USB or Bluetooth to perform a variety of tasks. With the addition of Camera Switches, more options have become available that leverage the front-facing camera and control certain operations on the device with nothing but a user's face.
Camera Switches currently supports a handful of gestures -- it is limited to just a few facial expressions: open mouth, smile, raise eyebrows, look left, look right, and look up -- for a few controls, though XDA notes it seems possible that the list of total control options could very easily grow in the future. In a few images posted to its coverage, XDA shows how a smile, raised eyebrows, or an open mouth that is detected by the front-facing camera can translate to different assigned tasks on the device.

When Camera Switches is active, a persistent notification icon that the front-facing camera is on will be active but Engadget notes that this feature may be unnecessary in Android 12 since it will include a status indicator for both the camera and Mic.
While not something for everyone, Camera Switches is part of the Accessibility Suite, which means it is targeted at those who might have problems navigating a phone with touch controls. Face commands are also silent, which means using them will be less intrusive in public or quiet environments than other methods like speaking out loud to a device.
The addition of Camera Switches to the Android 12 beta release seems to indicate that it will be part of the official launch of the operating system later this year. XDA was able to sideload the feature into Android 11 though, so it is possible that the feature will not be exclusive to Android 12 when it launches.

Samsung’s First Under Display Camera Appears to be a Mixed Bag
As part of its Unpacked event yesterday, Samsung announced two new folding smartphones. While there was a lot to "unpack" about each, one feature in the company's new flagship Galaxy Z Fold 3 doesn't appear to have flagship performance: its under-display camera.
Under-display cameras, or camera under-display (CUP) as they are sometimes called, are seen as the natural evolution of front-facing cameras in smartphones, as they eliminate the need for a notch or "hole punch" that breaks up a seamless display. The idea of hiding the camera under the display isn't new, but multiple companies have shown different design approaches to trying to solve a consistent problem with under-display cameras: the fact that there is a display in between the image sensor and the object that it is trying to image.
The first consumer smartphone to feature an under-display camera was the ZTE Axon 20 5G. As shown below by Marques Brownlee in January, while the camera is indeed mostly hidden under the display, it is still visible if you are looking for it and the image quality suffers mightily because of its position under the display.
Photos and videos taken with the ZTE's under-display camera are not only notably soft, but the pixels of the display are clearly visible in shots. So while the device was first to market, it was obviously first-generation.
Both Oppo and Xiaomi have recently announced under-display cameras that look worlds better than what the ZTE offers. While Oppo's is still a prototype, Xiaomi's a full-fledged finished product. There is clearly a new bar, which is what makes Samsung's integration of its first under-display camera a bit of a letdown.
In early testing from Linus Tech Tips , results from the Samsung Galaxy Z Fold 3 look very much like what was expected out of the ZTE smartphone, especially in backlit conditions.
However, Samsung seems to have implemented some serious software-based corrections into its device that makes it much more usable when lighting conditions are more favorable. In side-by-side comparisons, Linus found that the Z Fold 3 was heavily sharpening footage in real-time, which was visible when he moved slightly in frame. This does help fix the issue of softness with the under-display camera, and as long as no light is directly visible in the frame, appears to make it much more usable than what the ZTE offers.
Below are two similar shots using a front-facing camera. One uses the Z Fold2's hole-punch camera while the other uses the new Z Fold3 under-display camera. The difference appears minimal in this ideal use case.
Sammobile reports that in its opinion, Samsung did a valiant effort here, but it is undoubtedly a first generation result.
"At the end of the day, it’s the first generation Under-Display Camera from Samsung, and so far, it looks like a very promising and viable, albeit imperfect, technology," the publication writes.
As I said before, we need to face reality. In terms of the display of the under-screen camera, Fold3 is indeed the worst. But I believe the effect of taking pictures will be better. pic.twitter.com/UqTfRY3KST

The Verge also notes that it is quite obvious that there is a camera hidden in that spot, but it happens to be more noticeable in photos than in real life. Still, it's an imperfect solution. While certainly better than what came out just a few months ago, it's still not quite the replacement for the notch or hole punch many are after.

Oppo’s Next-Gen Under-Display Selfie Camera Appears Near Perfect
Several companies have been grappling with the physical issues that come with hiding a selfie camera behind a display, but Oppo seems to have cracked the code. Its next-generation under-display camera appears to have no distinguishable downsides when compared to one in a notch or hole-punch.
Oppo says that its new under-screen camera solution solves many of the technical and manufacturing-related challenges that have plagued manufacturers attempting for years. The company says that breakthroughs it has made have resolved issues like inconsistent display quality in the area above the under-display camera as well as the poor image quality that is caused by forcing a camera to shoot through a layer of display pixels.
Innovative pixel geometry of OPPO’s next-generation under-screen camera
The new technology uses several new innovations in structure design and artificial intelligence (AI) algorithms. Firstly, it uses what Oppo calls "innovative pixel geometry" to shrink the size of each pixel without decreasing the number of pixels to ensure a 400 pixel per inch (PPI) high-quality display even in the area right above the front-facing camera. It also uses transparent wiring in lieu of the traditional screen wiring with what Oppo calls an "innovative" new material. The company has also reduced the width of the wiring by 50%.
Oppo also claims it has improved the control of the screen's color and brightness:
"In contrast to the current industry standard of using 1-pixel circuit to drive 2 pixels (“1-to-2”) in the screen area above the camera, OPPO has introduced a new solution using proprietary screen technology, with each pixel circuit driving only 1 pixel (“1-to-1”)," the company says. "When combined with OPPO’s precise algorithmic compensation technology, this allows the chromaticity and brightness of the entire screen to be precisely controlled with a deviation of about 2%."
Oppo says that this improved control also improves the reliability and lifespan of the display, improving its expected life by up to 50%.
The camera itself was developed in tandem with a series of imaging AI algorithms including diffraction reduction, HDR and auto white balance to reduce the negative effects that are usually found with under-display cameras. The AI has also been trained to reduce diffraction and the result looks as though there is no screen in front of the camera at all.

For now, the technology is only part of prototype designs. While other companies have already implemented under-display cameras with lackluster results, Oppo appears to be the first to claim it has developed a camera that exists under a display that has no discernable, visual downsides from those that are housed in a notch or a "hole punch" that are ubiquitous in smartphone displays today.
