The iPhone 8 and Galaxy S8 may come with 'edge-to-edge' screens, how is that possible?

"Edge-to-edge," "bezel-less," "all-glass," "90% screen-to-body" - these are all terms bandied about by analysts and "insider sources" when it comes to the upcoming 2017 flagships from the world's top phone makers Apple and Samsung. We don't need to sell you on the benefits of having the largest possible screen area in the smallest possible footprint without compromising ergonomics and ease of use, of course, but if you can't help but wonder how Apple or Samsung are going to achieve it, look no further than this primer...

I my self will hate to see Bezel less Samsung phones. I like some bezels. The side bezels on the note 5 are just fine and I don't mind the top and bottom but if anything just make top and bottom smaller.

Yeah. On a second thought, the bezels on the iphones are actually perfect. Especially for comfort, landscape viewing and less accidental presses. Though the edge to edge bezels will be crazy though (and NO! I don't mean it in an MI MIX kind of way as I consider that phone ugly AF)

you think the iphone bezels are perfect? you kidding right? the 4.7inch screen models are bigger than my 5.2 galaxy

iPhone bezels have historically been large because Apple doesn't like the idea of just gluing everything together in a tight sandwich. Repairing an iPhone is a lot easier because of how they've designed it. If they do smaller bezels (iPhone users typically don't care), then they'll also have to figure out a way to keep repairability easy. As long as they don't turn to severely curved edge glass, I'll be happy. That crap is only feasible by Samsung's "glue everything together" standards.

Sorry, Android phones are better than iphone when it comes to repairability and screen/bezel ratio! LG G4 has 73% screen ratio, and got score of 8 on ifixit teardown. Meanwhile iphone 7 has 65% screen ratio and got only score of 7 on ifixit teardown! Apple tends to make all products unrepairable to increase turover (think Apple macbooks with glue everywhere!). That's apple business plan. Android beats iphone's non-fixiability anyday!

in term of comfortable use, yes. had LG G2, it's great in pocket, but not when using it. bezels are too thin especially the sides.

Eh, bezel has several advantages, it protects the screen, but ALSO it allows you somewhere to grip the phone without triggering screen. I enjoy my sgs7 edge, but I need a case or I simply can't hold it without near constantly triggering the screen because I have large hands apparently? or at least according to how it is designed?

True, edge-to-edge is certainly achievable from an engineering standpoint, but how will palm-rejection be executed, and how will software be augmented to cope with the unique "bezel-less challenges", remains to be seen...

How about a case that fits such a design to help protect it? How you going to make a case when you cant cover the sides because of no bezels?

"Our phones have fat bezels to protect your screen and for your fat fingers", said no phone manufacturer ever.

If only it was that, Genuinely large hands (from what it seems designed towards) simply cannot grip without fingers accidentally touching screen. If you do not have the problem, cool, be happy, those that do, well our man hands are apparently too big for the phone designs? or maybe designers have tiny hands?

Do these numbers mean that now there is 90% chance the display will break when it hits the floor?

Oh yes! Or maybe apple will employ a saphire display. If this happens though, many tech sites will turn having a saphire into a must have and a con if not included. *cough*PA*cough*

The next iPhone will be thinner which means thinner and weaker sapphire of it's used.

No one is going to use a Sapphire display because unless they perfect a way to make a man-made one vs using natural sapphire which is in very short supply and is very expensive, its not going to happen. EVER! Sapphire is one of the rarest minerals on the planet. That is why it is use for small things. That's why Apple bought a company tryign to make faux sapphire, like they do fauz diamonds. The process takes a small piece of real sapphire as a seed, and they try to use a machine which reies to duplicaed God's way of making such. Doesn't work. That's why Apple dropepd the idea and used what was yield for the glass to cover the home button and camera lens. Because the part is smaller and can have better yields results See the man-made process is very faulty. Out of 100 yields, less than 25% would actually be useful. The process takes months to do, and something that requires high yields will fail. Supply would never meet demand. You wont see sapphire glass used anytime soon if ever!

Design is the only thing that'll be exciting next year cause I see nothing new coming out in the smartphone world for the forseeable future. That being said, the iphone and samsung will kill it next year on design. I'm actually wondering which'll look better as they seem to be mostly thesame rumored design philosphy. If apple brings on the touchbar to the iphone 8 then it will be over for samsung. Samsung are really lucky to be first in releasing flagships otherwise.. Well, you know the rest! As for the camera, I feel samsung will still continue to own apple for some more years to come. I just really hope that samsung incorporates truly awesome tech in their dual camera system and that they put a secondary display on the edges of the screen (like the original galaxy note edge in a more rigid note 7 body). That'll be the best looking phone on planet earth if it happens (assuming apple ignores the touch bar on the iphone 8)

Yes. The days of dropping ones phone must now end.

Apple are going to achieve this because samsung are making it for them. And no other reason. Apple don't have the technical knowhow to actually make the screens etc

Cracked screens will now become a feature :D and the market for screens will now be the most profitable.

I can see it now. Manufacturers selling 300 million phones a year and 500+ million replacement screens. Screen manufacturers may soon start doing brisk business.

Like it or not, bezel-less/full-screen devices are the future. Touch rejection sw will be optimized for all these new devices.

^ And this article was quite longer than usual. The Galaxy S8 is giving me goosebumps already!

In the article there was a mention of a "active screen area" or something like that. I'm sure the "edge" parts of the screen would just be there for looks and not have an active digitizer in that area.

Funny how it seems PA is all gung-ho for Apple to possible use flexible displays that wrap around the phone. But when Samsung was first talking about such, everyone was talking about how gimmicky and useless it is and a waste of time and money. Those articles mentioned so much negativity towards Samsung, yet this article contains none against Apple. How about some negative as to why its a bad design. If you have a phone like the ones in the picture, where do you put a case to protect such a design? With no bezel, what will protect it when dropped? If the screen does indeed be on the top and sides like it shows in the render, where do you put the case? Will they design some type of snap on feature for the back? But if you do, you can' cover the sides, so how do you protect that? The S6/S7/Note 7 phones all break easy if the side of the phone makes contact with an object. Example, My Note 7 (original one) was sitting on the table and charging. I knocked it down, but was able to save it from hitting the floor by grabbing the cable. But the side of the phone hit the side of the charge and it cracked the glass right on the edge. Drop tests have shown that the glass is vulnerable mostly right on the curve of the glass itself. It is a nice eye-catching design, but it is flawed because it can't be protected. For a device you will handled 100's of times in a day or in an hour for many, the phone is going to be dropped at some point. What is going to be done to prevent breakage. And all those Samsung hating hypocrites who spoke against curved displays and saying its a useless gimmick, which I don't understand how a design to make the phone look good, which is its actual purpose can be gimmicky to begin with, are now going to have a similar design, yet I don't see PA or Apple fans speaking it against it. But for the last to years, we heard you all saying that yes it looks good, but that the design is useless and gimmicky, and already PA's tone has changed into sounding like they are looking forward to it, even calling it "ground-breaking". Just like us people who always have bought Samsung products or Android say about you hypocrites, everything is terrible and gimmicky and useless then you guys don't have it. You ridicule call names and pick fights, only for 3 years later to have the same thing, doing the exact same thing and because Apple is doing it, its now ground-breaking and appears to be a good idea. HYPOCRITES! That's why its so stupid when you idiot try to argue the iPhone is better. if its better than why is it every 3 years or so, Apple phone ends up being what we had 3 years before it? what is Apple going to bring to the curved displaythat Samsung hasn't done already? The whole point of the curved display was to progressively make the phone eventually become bezel-less. This was simply an evolutionary step in that direction. But Samsung decided to also add some usage other than just looks. Apple?
