back to article Apple iPhone 5 to sport CRT-style screen

Take with an appropriate quantity of sodium chloride: the iPhone 5 will sport a curved display. So say unnamed industry sources cited by DigiTimes, which also claims that, because makers of screen-covering glass are concerned about the high cost of kit capable of cutting curved glass, Apple has been buying such machines on their …

If it does infact have a curved display...

... it will be a conCAVE display, and not a conVEX (eg, like the Nexus S)

Concave

If I agree, got to be concave.

Seen on a few phones now, and it does feel a bit nicer in the hand.

Usually its just the "glass" that is curved, not the screen under it.

They will also sue Samsung for stealing their patented, innovative curved-screen design.

that makes sense because a convex display

would be impossible to protect with a case because the screen would stick out from the sides. Of course, a concave display would be stronger and less likely to get dinged in the middle where it wouldn't touch if dropped on its face.

Curved the other way surely

Would it not be curved in the same way as the Nexus S, so it wraps round your face better when you use it?

I haven't used a phone with this sort of display, but wouldn't a curved display be more likely to be damaged when the phone is dropped?

Already Done

>>> Unless Apple is planning some kind of glasses-free 3D display - maybe it'll work like a lens - adding a curved screen seems a bonkers idea to us.

Better tell that to the phone manufacturers already producing them, then. The Nexus S has a curved screen.

Curved screen

It's not that weird. My Google Nexus S has a curved display and it works very well against mirroring light sources when watching video.

Built-in telly?

It'd be incredibly cool if they built a proper CRT into the next iphone. We could have proper built-in telly at last! One thing though, is it going to be PAL or NTSC? Or does the rumour of it being a world-phone mean it'll do both?

Once again, outstanding reporting el reg!

Probably

It most probably will be some proprietary variant of SECAM.

(Side question: When the UK adopted colour television, we had no need for it to be compatible with existing mono receivers; since our old mono sets used 405 lines and VHF frequencies, and we were moving to a completely new, 625 line system transmitted on UHF frequencies. Why, then, did we adopt PAL -- a luma-chroma system where colour rendition is compromised by the ability to remain compatible with existing mono receivers -- instead of an RGB-based colour system?)

625 line and colour

The introduction 625 line and PAL didn't occur at the same time, 625 line leading by a few years. Beyond that, a non-luminance based system would have added significant cost to the more common B&W sets of the time.

It would be very different today of course.

Think Glasses...

If true, I guess this is to reduce reflections. Flat glass surfaces always reflect a lit more light than curved ones.

That's how you can tell when an actor in a Hollywood film is wearing fake glasses.

So a slightly curved screen may help cut down on reflections caused by artificial light sources.

I can't see it doing much for sky reflections though, as that's one huge light source :-)

"Flat glass surfaces...

"always reflect a lit more light than curved ones."

Science fail.

As a pedant: they always reflect more light *in the same direction*, compared to curved ones.

But it should certainly mean that, done correctly, it would be better for viewing under certain light sources.

(Sorry, moody Monday morning)

Correct...

I should have added the "in the same direction".

Obviously, total reflection will be the same for the same type of material whether curved or flat.

Good Pedantry my friend!

Oh Fresnel Equations, my title is too long!

The percentage of the total incident flux that is reflected really does vary according to curvature. (Hint: some light is transmitted, because glass is, y'know, transparent [to visible frequencies].)

Not reflections or strength

@“I guess this is to reduce reflections”

No it won't reduce reflections, it will increase them.

When a viewer is looking at a curved screen (on a phone) the curvature means the reflections come from a wider field of view (due to the curvature). This means if there is any bright irritating light sources in your field of view, the curved screen will make it harder to avoid these bright reflections on the screen compared with a flat screen. Its why flat screens were better than CRT monitors (and as an old programmer I've suffered the pains of curved screens and of trying to avoid reflections on them). Its why I would much sooner have a flat screen.

I would bet this curved screen has nothing to do with helping the screen image, or being stronger when curved (try accidentally standing on it and see how long that curved screen (and case?) will last, as then all the force is applied to one central point on the phone glass. A curve is only stronger when load bearing in the air when used as an arch compared with a flat beam. A curve isn't stronger when its on a flat surface as a flat phone dissipates the load over the whole surface whereas a curve is forced to bend in the middle when pushed from above with one point contact in the middle).

So its not likely stronger or better for viewing. So whats it for? ... I bet the curve is to give Apple users another reason to be smug, because it stands out as an iphone 5, “hey look everyone I'vvveee gooot a neeeewww iphone fiiivee and you can all see its an iphone 5 by its curved screen, as thats the only one with this look!” ... oh joy, I can't wait to be subjected to it. :(

Match your bodily curves

If it's curved then it should fit in your pocket better and not look like you're carrying a brick (albeit a thin brick) in your pocket.

Perhaps they come with different radius curves to fit different people or body parts

No no no

If the curve of your body doesn't fit the phone you're doing it wrong. Just get a different body, not that big of a deal.

Of course - the bRA-phone

'Just the right curve to match yours!' - available from C to J!

(insert very poor-taste comment about A & B sizes buying the normal flat-screen version.)

Alternatively maybe Apple are planning a head-phone carrying unit that allows the iPhone to drop down in front of the eyes and show a virtual reality display - think like Geordi LaForges glasses, but about the size of a paperback.

Apple emulating car manufacturers - a touch here and another there

Obviously Jobs mob is getting desperate to maintain repeat sales.

All they appear to be doing is making slight changes so Iphans can differentiate between new models and clunkers and, Jobs hopes, it will generate yet more sales as Iphans slavishly buy yet more of the same.

Worked for years for car manufacturers, why not other products?

CRT screen are convex for a reason

CRT's have convex curvature due the physics of the internal electron beam emanating from what is essentially a point source, not due to a convex display giving a better viewing experience. It doesn't, which is why over the history of the CRT, considerable R&D effort went onto cheap but complex electron beam steering systems in the CRT tube itself in order to make CRT's as flat as possible. That is why through the 1990's, the flatter the TV screen, the more expensive. The biggest boon towards flat screen CRT's was cheap "fast enough" digital processing in the late 1990's, which allowed correction for pincushion and keystone distortion digitally while using simpler beam steering in the CRT tube itself.

CRT screen are convex for more than one reason

CRT screens are convex for strength as well. Don't forget the semi-vacuum inside. Flat CRT screens need to be thicker and are therefor heavier and more expensive to manufacture and transport.

Who says it is the screen..

The Iphone4 has a glass back doesn't it? Maybe it is that they want to curve? maybe even make touch-sensitive and curved?

Phone manufacturers occasionally play with 'back controls' and they all tout it as the next great thing in user interaction; then quietly drop for the next model since it actually sucks (I have a LG viewty with a 'rear scrolling control' that turned out to be a total waste of space..)

But maybe Apple have found a way to get it usable and functional.. they are certainly clever and innovative enough to have a real chance at letting the hand holding the phone do more than just thumbpress side buttons.

Smoke 'em Out

Ignore this rumour - Apple are simply trying to flush out people in their supply chain who leak future product info. When manufacturing partners are announced, compare the ones who didn't get selected to where the rumours originated from.

Not that amazing

The Nexus S, of course, has a curved screen, and it's not unknown for customers who want a large amount of something weird to contribute up-front to the tooling; in fact, Apple has been known to do this before. I'd be sort of surprised if this was true, though; for the Nexus S the curve was really just a gimmick which everyone forgot about, and there's no use being the second company with a weird-shaped screen.

It's only taken Apple 15 years to copy

The first and still the best banana phone ala the Nokia 8110 as made famous in the first Matrix movie.

I can still remember how cool it felt to press a button on the phone and the front extended to expose the keyboard and mould perfectly to my face.

Well done indeed Apple.

Close, but no banana

Sorry to be picky but...............whilst you were correct in saying it was indeed the Nokia 8110 that was featured in the Matrix film, the phone with push button slide was the in fact the 7110. The 8110 had been discontinued by Nokia several years before the Matrix was released. The 7110 was released and marketed alongside the film, leading to the confusion.

"Curved glass surfaces...

As a pedant: Assuming the phone chassis remains the same between curved and non curved versions a curved surface will have more total surface area, and therefore reflecting more light *in any direction*, than a flat surface.

Headmaster

faulty pedant!

Wrong.

The amount of reflected light is determined by the planar area of the perimeter. If anything, a curved surface will reflect less of the incident light than a flat surface because no material is 100% reflective (not considering quantum materials and events) and so the larger curved surface results in greater loss of incoming light.
