For decades, we’ve lived with an inconvenient technological truth: Cameras and other sensors cannot occupy the same space as our screens. It’s why, increasingly, smartphones rely on the dreaded “notch” as a way of maximizing screen-to-body ratios while preserving the front-facing camera and other sensors.

Some phone makers, from Oppo to OnePlus, get around this problem by using motorized pop-up cameras, while others have resorted to punching holes in displays to provide the camera with its own peephole. It’s also why even the latest high-end laptops still have pronounced bezels around their displays. The webcam needs a home and it seems no one is willing to live with a notch or hole-punch on a computer.

But it turns out that cameras and screens aren’t quite as incompatible as they seem. Thanks to improvements in manufacturing techniques, these two adversaries are about to end their long-standing territorial dispute. This isn’t a far-flung prediction; it’s happening right now.

Complaining about a phone notch, hole-punch or a large screen bezel is the very definition of a first-world problem. And judging from Apple’s stellar sales numbers, none of these side effects of forward-facing cameras are dealbreakers for buyers.

First, it lets you make phones that have true edge-to-edge screens. Videos and photos look better, and app developers can make use of every square millimeter for their designs — all while keeping the phone’s body as small as possible.

Second, from a design and manufacturing point of view, if cameras and sensors can be placed anywhere, with fewer restrictions on their size and visibility, it redraws the map for phone design. Bigger batteries, thinner phones, more sensors, and much better cameras are all potential upsides.

Cameras placed in bezels or notches create the now all-too-familiar, awkward downward gaze that happens during video calls. “Most of the time, you’re not actually looking at each other when you’re talking over video chat,” Michael Helander, CEO at Toronto-based OTI Lumionics told Digital Trends. “The current placement of videoconferencing cameras in all of these devices is really suboptimal.”

Helander has probably thought about this problem more than most. His company creates specialty materials that enable what was once impossible — making displays transparent enough that you can place a camera behind them.

Once a camera is sitting behind the display, it will finally make our video interactions look and feel like real, in-person interactions — a game changer that couldn’t come at a better time in our COVID-restricted world.

Screen technology is dominated by two kinds of displays. The most common are liquid crystal displays (LCD), which include LED TVs and QLED TVs. The second, organic light-emitting diode (OLED), dominates smartphones and tablets, and is growing in use in laptops and even desktop monitors

LCDs are actually transparent when not in use — that’s why you see a gray background on a calculator screen wherever the black digit segments aren’t active. But taking advantage of this transparency to take a photo poses big technical hurdles, especially once you factor in the need for a backlight.

One solution favored by Xiaomi and Oppo in their UDC prototypes is to rely on an OLED pixel’s inherent transparency. When an OLED pixel isn’t being used to emit light, it lets light in. So you can place a camera behind an OLED display and it will be able to gather enough light to capture images. But there’s a catch: You still need to place the camera at the top or bottom of the screen, because when the camera is active, the OLED pixels above it must be shut off, which creates a temporary black area on the screen. That approach is a solution to the notch and hole-punch problem, but it does nothing to solve the downward gaze issue.

The first commercially available phone with an under-display camera — the ZTE Axon 20 5G — uses this technique, but it also suffers from a less-than-ideal compromise. Modern smartphones have incredibly densely packed pixels. The iPhone 12 Pro has a 460ppi (pixels per inch) display, which means that there are more than 200,000 pixels in one square inch. Sony’s Xperia XZ Premium had a whopping 807ppi screen (more than 650,000 pixels per square inch).

Punching holes in between those pixels, even with a laser, is so tricky that ZTE had to remove some pixels from the area above the camera to buy some extra room. The result is a noticeably lower-resolution square on the screen.

A lower-resolution section of the screen might not bother you when it’s near the top, in an area that’s used mostly for inconsequential information. But few people would accept such an obvious reduction of resolution in the center of their phone’s display, which is what we would need to counteract the downward-gaze problem.

Helander claims the self-assembly process works on any screen size, and lets manufacturers decide how many openings are needed — from just one to 1 billion.

As exciting as it is to think that we’ll soon be able to have much more natural video calls, placing a camera under a display puts an even bigger onus on manufacturers to provide trustworthy privacy measures.

We’ll need some kind of reliable indicator of when the camera is active and an equally reliable way of disabling it. Because it’s under the screen, there’s no way to physically block the lens without blocking content on the screen as well.

Apple recently updated iOS to show a small green dot near the notch when its forward-facing camera is in use, and an orange dot to show when the mic is active. That’s a good way to inform us of what’s going on, but we need something more.

Smart speakers like the Google Nest mini ship with physical switches that can be used to disable the microphones. Assuming that there’s no way to remotely overcome the switch’s position, it provides a very good level of trust. A similar mechanism on TVs, monitors, and laptops should come standard once cameras become invisible.

OTI Lumionics already has agreements in place with several Chinese smartphone manufacturers, but due to confidentiality restrictions, these companies can’t be named just yet. “Many of them have prototype phones that have been built and everything looks great,” Helander notes, “but none of them want to disclose anything publicly until they’re ready for their actual official product announcements.” He’s confident that we’ll see these new under-display camera models sometime in 2021, although they may remain a Chinese market exclusive until 2022.

For years, smartphone manufacturers have tried numerous ways to create a truly edge-to-edge display. The ultimate aim is to have a smartphone with a screen that reaches to all four edges of the frame, with no interruption.

The only issue has been the need for a selfie camera. That inevitably has be be put somewhere, and we"ve seen any number of inventive methods that aim to try to hide it, make it less of an obstruction, or at least, reduce its visual impact.

There have been pop-up camera mechanisms, tiny dewdrop notches, flip cameras, and punch-hole cameras put on the front of phones. But there is one new technology aimed at hiding it completely: the under-display camera. Also known as USC (under-screen camera) or UPC (under-panel camera).

Thankfully, the clue is very clearly in the description. The UPC/USC or under display camera is a camera that"s hidden behind the display panel of the smartphone.

In basic terms, it"s similar to in-display optical fingerprint sensors. A small portion of the display panel is transparent, and lets light through to a camera that"s sat behind the display. Or to be more technically accurate, a small portion near the top of the screen is actually a second, tiny transparent display.

If you"re wondering why they can"t do what they do with optical fingerprint sensors and just make a transparent portion of the main screen yet, it"s because standard OLED panels aren"t yet able to let enough light through to the other side to create a decent coloured image. So for now, companies like ZTE and Xiaomi have resorted to using a secondary, much smaller "invisible" display within a display.

And, if they used this display as the entire panel, that would have dire consequences for the fidelity of the image on the display. So they put it in a part of the screen where - most of the time - the quality of the image doesn"t matter: in the status bar.

While the eventual aim is surely to have it implemented in a way that makes it completely invisible, early iterations haven"t quite managed it. It"s mostly invisible on darker days, but once you shine light on the area of the display hiding the camera, you can clearly see the area that"s allowing light through. As technology develops, we expect this to improve.

The first phone to have the under-screen camera was the ZTE Axon 20 5G. So far it"s also the only commercially available product with the under-display camera.

As mentioned already, part of the reason is that it"s not possible (yet) to completely hide that secondary transparent screen. The other problem is to do with image quality from the camera that"s behind it.

By adding a layer of material that"s not completely clear in front of a camera, it makes it harder to get a really good photo. After all, cameras require light to take pictures, but crucially, also need that light to come through to the sensor without any disturbance to the signal in order produce sharp and accurate results.

This is an extreme over-simplification, but it"s almost like covering the camera with a really thin layer of tracing paper and asking it to take as good a picture as if you hadn"t. It just can"t be done. Or hasn"t been so far.

The aim undoubtedly is to make the transparent display portion more transparent, but also develop better AI/algorithms to correct the issues that arise from filtering light through the screen.

The R1 mirror is a backup camera monitor which is compatible with most vehicles – making your car, truck, or SUV safer without having to purchase a new ride.

The R1 works as seamlessly as back-up cameras built into newer vehicles. But instead of a separate screen, the R1 has a built-in LCD screen connected to the cameras installed at the front and rear of your vehicle.

R1’s hidden environment sensor automatically adjusts the brightness of the LCD depending on the lighting. When an R1 connects to a C3 camera, the LEDs on the camera will also adapt to external lighting.

The R1’s “auto-switching” inputs automatically display the rear camera on the LCD when in reverse gear, and the front camera if in drive gear. Manual activation is accessible by pressing “M” on your device.

As is often the case with new technology, under-display cameras didn’t make a great first impression. It’s a nice idea in theory, of course — you don’t need a notch or a hole-punch if you can put a selfie camera under the display — but the earliest efforts had some issues.

ZTE’s Axon 20 last year was the first phone to ship with one, and it was bad. The camera quality was incredibly poor, and the area of the screen looked more distracting than a notch. Samsung followed up this year with the Galaxy Z Fold 3, which had similar issues.

But things are actually getting better. Two newer phones on the market, Xiaomi’s Mix 4 and ZTE’s Axon 30, use a different approach to the technology, and it’s an improvement on the previous generation. Instead of having a lower resolution area of the screen that allows light through to the camera, they shrink the size of the pixels without reducing the number.

This means that the part of the screen that covers the camera is really difficult to see in normal use. Look at how the Axon 30 compares to the Axon 20 on a white background, which was the most challenging situation for the older phone to disguise the camera in. It’s also much harder to make out than the camera on Samsung’s Galaxy Z Fold 3:

ZTE’s Axon 20 on the left, and the newer Axon 30 on the right. The area of the screen that covers the selfie camera is much less noticeable on the Axon 30.

Now, the camera is clearly still compromised compared to one that doesn’t have to gather light from behind a screen. ZTE and Xiaomi lean hard on algorithms for post-processing — you can tell because the live image preview looks much worse than the final picture. The results still look over-processed and unnatural, even if they’re more usable than their predecessors’. Video quality is also bad, because it’s probably too much to ask for these phones to do the processing in real time.

There’s more to the idea than just reducing the size of your phone bezels, though. We spoke to Steven Bathiche from Microsoft’s Applied Sciences group on how the company is working on under-display cameras for an entirely different reason — so you can maintain eye contact while looking at your screen on video calls.

An everyday LCD screen has been modified to “see” the world in front of it in 3D. That means a viewer can control on-screen objects by waving their arms in the air without touching the screen, let alone a mouse or keyboard.

The screen – dubbed BiDi, short for bi-directional – allows users to manipulate or interact with objects on the screen in three dimensions. It will also function as a 3D scanner, he adds. “If you spin an object in front of screen, the software will stitch together a 3D image.”

Raskar and Holtzman’s team were inspired by the way manufacturers of LCD panels, including Sharp and Planar Systems, are experimenting with adding optical sensors between a panel’s pixels so that it can act as a touch-screen interface.

But such displays have poor vision, like a camera with no lens, says Lanman: they can clearly image objects that are in direct contact with the screen, but anything further away is blurred. The researchers set out to modify the concept to let the screen see the world in front of it more sharply.

Placing a tiny lens slightly in front of each sensor would do that, but the layer of lenses would adversely affect the images produced by the display. Instead, Raskar and Holtzman’s team used a standard 20-inch screen to show how a basic feature of all LCD screens can perform the job of a lens array.

The brightness of each of an LCD’s pixels is controlled by a layer of liquid crystals, which can swivel to physically control how much light passes from the display’s backlight. In BiDi the team use that function to control light passing in the other direction onto an array of sensors behind the display.

When the screen is “looking” around it, most of its pixels are shut off by the liquid crystals. But a regular grid of hundreds of pixels spread across the screen use their liquid crystals to create a tiny hole that acts as a pinhole camera lens, focusing an image of the scene in front onto a thin translucent film a few centimetres behind the LCD. Those images are detected by a camera inside BiDi, allowing the device to know what is happening before it.

The LCD screen’s pixels must also do their usual job of presenting images to the user, though. They oscillate between their two tasks many times per second, too fast for the viewer to notice that while they are watching the screen, the screen is also watching them. “We take the normal LCD layer and put it to double duty,” says Lanman.

Exploiting the different viewpoints of pinholes in different places on the screen makes it possible to reconstruct stereoscopic images, by taking a small amount of information from each of the pinhole images. Several stereoscopic image pairs are produced, each sharply focussed on objects a particular distance from the screen, from which the system can calculate how far away the object is.

“We produce multiple images, each focused on a different plane in front of the screen all the way to, say, 50 centimetres away from the screen,” says Lanman. “For instance, your hand will be blurred except in the one image that’s at the right depth.”

A further processing step singles out the sharply focussed parts of each image in the stack, creating a sharp depth map of objects within the screen’s field of view that can be used to track 3D gestures in the same way a standard touch screen captures touch gestures.

The Feelworld Lut7 monitor is a great find for this price. The 2200nit Touch Screen is a MUST HAVE. I have been able to use it on bright, sunny, beach days without the need for an additional sun-hood because of how bright it gets. That brightness will also save you on those cloudy, overcast days. On-camera monitors tend to throw back a harsh, almost mirror-like, reflection where the Feelworld Lut7 is clean and easy to see (see video for an example and an unboxing). The 7inch screen is nice because it allows you to pull up other items like RGB Parade, Vectorscopes, Grids, Audio Levels, etc. and still have plenty of room to monitor your video (again see video example). This monitor has a lot of the professional features you would find on much pricier models at a more affordable price. False Colors, RGB Parade, Wave, Vectorscope, Audio Bars, Audio and HMDI Out, LUT support...I could go on an on. Again, for this price range it is a great monitor!

There"s not much in the way of independent footage of this phone, but YouTuber AmazTech has thoughtfully pointed a flashlight at the display, which reveals the camera.

ZTE has officially announced the world"s first commercial phone with a behind-the-screen camera: the ZTE Axon 20 5G. Shrinking phone bezels have made locating the front camera a major design point of phones for the past few years. We"ve seen big camera notches, small camera notches,round camera cutouts, and pop-up cameras. Rather than any of those compromises, the under-display camera lets you just put the camera under the display, and by peering through the pixels, you can still take a picture. It"s the holy grail of front-camera design.

As we"ve seen in explainers from Xiaomi, these under-display cameras work by thinning out the pixels above the display, either by reducing the number of pixels or by making the pixels smaller, which allows more light to reach the camera. In the area above the camera, manufacturers will have to strike a balance between a denser display with lower-quality camera results or better camera output in exchange for an uglier above-the-camera display.

ZTE"s official renders of the device claim the camera is completely invisible, which can"t be right. It"s standard practice to not make any attempt at a realistic-looking pixel display in these renders, but in this case, that"s a big deal, since the display should look slightly darker above the camera. With COVID cutting down everyone"s ability to travel, there isn"t much in the way of live footage of the phone, either. ZTE posted an official live video to Weibo that really goes out of its way to never linger on a close-up shot of the camera, which is highly suspicious given the camera is the phone"s only headline feature. The best footage we can find right now is a YouTube unboxing from AmazTech, which at least takes the time to scrutinize the sensor location. AmazTech doesn"t have the sharpest video quality on Earth, but it doesn"t seem like ZTE has a lot to hide: the camera is still hard to spot. I would still like a better look at the screen, particularly with lower brightness levels, but so far it looks amazing. Advertisement

Covering the fancy new camera tech is a 6.92-inch 2460×1080 OLED display. The base model phone has a Snapdragon 765G SoC, 6GB of RAM, 128GB of storage, a 4220mAh battery, and a bunch of other unremarkable specs. ZTE lists Chinese prices starting at ¥2198 ($321). Huawei gets all of the "banned in the USA" headlines, but ZTE isn"t welcome in the United States either. That means you shouldn"t expect much in the way of distribution.

Although Chinese manufacturers usually get the jump on new technology like this, everyone picks from the same parts bin. So you can expect to see under-display cameras from most major Android manufacturers in the next year or two. This also means we"re rocketing toward the age of the completely invisible camera, a privacy-nightmare world where any device with a screen could secretly be recording your every movement. We"ve already run into devices that can discretely include microphones, and last year Google got into hot water for shipping a device with an undisclosed microphone. Now we get to do this with cameras! Welcome to the future, I guess.

Under-display cameras are poised to be The Hot New Feature, following up on the similar success of the in-display fingerprint sensor. It almost seems like science fiction: You can"t see the camera, but it can see you. The technology promises to eliminate the last impediment in the all-screen phone dream. But how does it work, and when will you actually be able to buy a phone that has one?

According to Helander, there are two engineering approaches to designing under-display cameras: You either do everything you can to make the entire display as transparent as possible above the camera, or you essentially make tiny transparent holes in an otherwise opaque screen between the pixels.

In the first case, that means changing materials and rearranging things in the area above the camera. Certain metals in the various layers can be replaced by transparent conducting materials like indium tin oxide, and the structure of the display itself can be rearranged to reroute anything that might interfere with optimal transparency in that area. Anything that can"t ultimately be moved or made transparent can be made as small as possible.

There are a few limitations to this route: primarily brightness, uniformity, and resolution. Typically, OLED pixels are designed to be reflective on one side and transparent on the other, ensuring most of the light produced goes in one direction: toward you. Making the display transparent in one section interferes with that sort of design, and it can make the area the camera is in look distinctly different and less bright than the rest of the screen. Compensating for that effect by cranking brightness and calibrating differently in that tiny area can result in other long-term issues like burn-in around the transparent camera area. We"re also told that all the rerouting and transparency-increasing steps often mean accepting a lower display resolution in that particular spot — a handful of big pixels in a sea of smaller ones. This is allegedly the approach that ZTE is taking in devices like the Axon 20 5G.

The second method is a little different. Rather than making an entire stack of the display transparent across one area, you can carve out individual transparent "holes" between the pixels and rely on them to transmit light through the screen. You can do this in a few different ways, like cutting down on display resolution to carve out an area for one in every X number of pixels, or just shuffling and rerouting things to make regular patterned spaces.

As before, this means rerouting some components to ensure you have a clear line through the screen, but you don"t have to worry about the whole display stack being transparent, just specific spots at regular intervals. If your resolution is low enough, you can accommodate these extra holes without any loss, but at very high densities, it can also mean giving up some pixels and accepting a lower resolution. Importantly, though, this route means the individual pixels above the camera have the same individual brightness and performance characteristics of the pixels elsewhere on the display, so you shouldn"t have as many issues with uniformity. This second route is what we"re told Xiaomi is planning for its upcoming phones, and it sounds like it may work the best out of the possible solutions available right now.

Now, whichever route manufacturers take, under-display cameras won"t work quite the same as they did before. Either way, the camera is going to get a little less light with more stuff in the way, and there are other optical effects these designs have to fight. There are issues like reflection and diffraction from all the various materials, layers, and holes that the light travels through. These are problems that can"t be fully eliminated, but Helander tells us they can be compensated for in software and reduced by advances in material science and engineering. Some of these issues also result in "softer" looking images, mimicking some of the effects of the beauty filters so many people enjoy, so it isn"t all bad. Helander also claims that machine learning models can compensate for many of these issues pretty well.

This also opens a pretty big door for us in the future. Right now, most under-display prototypes just put the camera in the same place and extend the screen to cover it, but nothing is stopping us from using some of these solutions to make the entire display transparent and putting the camera wherever we like. Ultimately, we could move the camera down to the center of the screen, making it easier to keep the effect of eye contact when in video calls, or we could even toss several cameras under the screen in different places. Some day other optical sensors, like the infrared cameras used for face unlock systems, could also be moved under the screen. Eventually, we could do the same with desktop computer monitors, too.

Before this technology can replace the notch or the hole-punch cutout, it needs to be scaled up. And given the sort of engineering costs involved, Helander tells us that, counter-intuitively, we"ll see this technology roll out in the mid-range market first. Right now, sacrifices required when it comes to resolution and brightness mean this technology probably won"t be a good fit in the flagship space for a while, where customers expect the very best. Issues like a big gray square or circle in the screen at max brightness, a resolution drop in one corner, or an overall lower display resolution all won"t play at the thousand-dollar price point, but they"re more acceptable in a mid-range product, and the details of ZTE"s upcoming device lend further evidence to that argument.

In Helander"s estimation, it could be 2022 or 2023 before this technology becomes mainstream, engineering problems are solved, production ramps up, and the feature works its way up and down the market. In the meantime, most of us will have to make do with being able to actually see our camera in a bezel, notch, or hole-punch cutout.
