[TechSpot] Samsung's plans to kill the notch: Yes, please.

Highly anticipated: Samsung was sprinting towards bezel-lessness before other companies could find the start line, and now it looks like they’re about to make a home run. A leaked image from their secretive OLED Forum on Thursday reveals that not only do they have plans for an under-screen fingerprint scanner, but under-screen stereo speakers, haptic engines, and best of all: a camera. What’s more, a separate leak says they’ve got prototypes.

I don't think that the author of the article realizes the insidious implications that this has to whatever little shred of privacy people have left. Also apply this to laptops and smart TVs and home assistants and smart fridges and car infotainment systems and you won't be able to cover the camera anymore without blocking part of the screen. The right way to go if they really want more screen real estate is a pop-up camera (ideally make it for both front and rear cameras in smartphones).

As far as privacy concerns, I'm not sure if you can yield a good image from computationally removing the light from the pixels that are directly over the camera (after all those are known by the system). I would assume that it's unlikely with the screen near or at maximum brightness since the wells in each pixel have quite low capacity due to the tiny size of these pixels compared to on larger format sensors which can handle far more light prior to clipping. You would need some extremely high readout speeds (which right now gives pretty high noise) and some computational imagery to get a usable photo when the screen is on. As of now there's a good probability of the screen above the pixels needing to be off in order to get a good photo. In that sense, this is actually good on a privacy front because it would be quite obvious when something is using your camera just like pop-up cameras. I don't see pop-up cameras getting anywhere due to the amount of moving parts it needs as well as the chunk of space those moving parts all need.

This wouldn't matter when the screen is off because then it would be just like any normal camera sitting in a bezel unobstructed by anything.

It would have to take another decade or two before we get high sensitivity high speed readout image sensors (Quanta Image Sensors and jots are already being developed by Eric Fossum, the inventor of the modern day CMOS image sensor) in which this would become a larger concern.

On the technology itself, I'm looking forward to it. I'd like to be able to reach the Svper Phone concept that helped push forward this "bezel-less" trend, though there should still be some bezel like on the iPhone X/XS to help mitigate accidentally presses.

As for how soon we'll see it, since it's already in prototype stage, probably in the next 5 years? Probably in the iPhone 12 or 13 since those are the major redesigns and the S ones are just optimizations. I assume they've solved the problem of distortion from light passing through the subpixel array (in principle this would work just like software lens distortion corrections) and have made the display glass "fast" enough that there isn't a much of a problem with placing a sensor underneath.

The under-screen speaker technology is interesting. I'd venture it's quite close to what Sony is doing with their flagship Bravia televisions (Acoustic Surface). Worried about how the sound might distort though when users press on the screen. If it does distort on contact then it would be quite jarring if you're ever listening to music on the speakers while using another app, or in the case of video, using picture-in-picture or split screen.

Last I heard the reason so many phones use screens with notches is because the types and resolutions of screens manufacturers want to use are exclusively notched. Good to see regular, non-dumb-looking screens arrive.

Cameras underneath the screen are a really neat idea though. At that point you end up with what is essentially a digital mirror. I wouldn't be too concerned with privacy issues given that cameras are already small and widespread. Sure, you can't cover it easily, but in order to transmit and phone home it needs a connection. Can't mine data if there's no way to leave the system. Internet connection would require access to a network (which can be blocked), cellular modems (which would NOT be subtle given FCC rules), or somehow piggybacking off a video cable and sending data through the cable box (idk but that's the only other connection you'd really have lol).

That doesn't sound right. There are many phones out there with different sized notches. Google's phone being the biggest one out there.

would I prefer notch-less? sure...who doesn't want a cleaner design

but people are overreacting...probably the same people who has to apply a snapchat filter to every selfie because they're so out of touch with reality and that the most minor asymmetry/imperfection has become an atrocity against humanity

seriously? if you're worried about privacy, why are you even using a smartphone let alone the Internet.

and a phone with a pop-up mechanism is sure fire wire for more planned obsolescence…they'll make the spring fail after few hundred clicks

I personally don't think the notch on the iPhone that big of a deal at all.. the notch combined with the bottom bezel on the Pixel though is hideous

Wait, people... care, about this? As in, they have at down and thought about it and it would actually make them [momentarily] happy for this to be, whatever it actually is, because I read the whole article trying to figure out and I'm still stumped. I mean, it's a phone. With a touchscreen. Great. I'm still trying to understand what I'm supposed to be excited about. It's kind of like choosing between shades of white - should I go Swiss coffee or tope?

I have an S9. It's getting sold as soon as these are available.

I calculated the odds of this succeeding versus the odds I was doing something incredibly stupid... and I went ahead anyway.

If it's not coming out for the PC, it's dead to me.

My mate got one recently and I had a look at it and it doesn't bother me at all. He showed me a video in YouTube as well and you can't even tell the notch is there (which was my only potential concern).

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

Interesting. They shrunk the bezels instead of adding a notch. What a novel idea.
