Re: Stantum's Multi-Touch resistive display
 

There is of course another advantage of capacitive over resistive.

Durability!

The screens are able to be made of glass, they are stronger, less prone to scratches, don't get 'clicky' after a few months of use, still work if the screen is shattered, can withstand heat (say an ember from a cigarette floats down onto your phone screen).

Re: Stantum's Multi-Touch resistive display
 

If the glass is so durable and scratch resistant, why wasn't flexible glass invented?
http://en.wikipedia.org/wiki/Flexible_glass
http://www.technologyreview.com/computing/25429/?a=f
It could be used for resistive screen ;)


:)

First, resistive screen is already based on two flexible sheets, and we don't finger the motherboard.
The problem was that flexible and glass are incompatible, and the glass is the most scratch-resistant material for a screen (or described so) and is used in capacitive screens, so I asked why there is no flexible glass.

Second, it's true that manufacturers cannot afford to produce immortal devices and most consumers don't want their devices to be immortal (because they would have to find a way to upgrade their processors, RAM, camera, and other modules in order not to be left behind), and thus immortal devices become very rare and expensive.

Third, the watch you described is a ludicrous luxury. Not customisable? Not repairable? I already have mechanical watch and normal non-digital compass; if I find mechanical barometer, I will be able to see altitude, too. Without capricious electronics.
Though I would like to have all these mechanical watch, magnetic compass and barometer miniaturised and put inside a finger rind, where I can look at them through a Stanhope lens
http://en.wikipedia.org/wiki/Stanhop...tical_bijou%29
It would be convenient, require no electrical power, compact, and well-protected against viruses/electromagnetic waves. At maximum, the compass could be confused by magnetic fields. And it would probably last longer, than tactile screen. The main problem would be miniaturisation of mechanical watch, I think.

Re: Stantum's Multi-Touch resistive display
 

Except not really.

The 'durability' of a capacitive screen is a very limited one. It won't VISIBLY scratch, but microscratches (real 'micro' scratches - the microscopic ones that you won't see ever without special equipment) are going to screw up exactly how the current passes through it. That combined with other changes to resistivity/conductivity of the screen material basically mean that a capacitive screen is GUARANTEED to get less accurate over time. Where-as resistive screens are only really screwed if you have blatantly visible scratches. And even then they still WORK just as well unless the scratch/damage completely cuts a section of the grid, albeit at that point they aren't pleasant to look at.

Of course, better screen materials mean that over time, it becomes easier to make the screen even harder, thus more resistant to microscratches, and other changes could be made that improve resistance to changes in conductivity/resistivity or the surface.

But by the same token, improvements in resistive screen materials also would lead to greater durability at the aesthetic macro level.

So we're back to them having different disadvantages, of which I personally see the resistive screen as being the better off yet again.

Re: Stantum's Multi-Touch resistive display
 

Because you'd be fingering the motherboard if the screen would be flexible. :D

We have the technology to make immortal screens, it's just that none of us can afford it. Diamond surfaces are achievable and are virtually immune to scratching assuming you have a cash fountain you no longer need.

Or, assuming you can live with a less-than-one-inch screen. Watches have very-very-tough screens since forever.

Tissot used to sell a sapphire screen with touch for a watch, IIRC. <Google>. Here we go. "By simply pushing the crown and then touching the tactile crystal at different positions these functions can be activated. Touch the screen at two o'clock and your current altitude appears on the digital readout. Touch the crystal at six o'clock and the hands move around into position to become a compass". About a thousand USD, before you ask. ~30 mm diameter, before you ask.

English is not my first language, but i speak (not to mention write) way better than many native speakers (or so i've been told), english not being your first tongue is no excuse to suck at it.

@wikiwide

Glass is better than plastic, true, but don't believe the hype. The reason most capacitives last longer is because they don't work by harn on hard surface. If you took a dusty pen and kept on sweeping you'd nuke that too. Plus, the deeps scratches are unavoidable.

I'd like a phone with a user-remvable touch so you can buy them like covers. They are not so expeensive. I heard quotes in the 50$ area. I plan on a screen replacement at some point.

So it's also a price thing. If a glass screen would make the device 50$ more, it would not be feasable. Personally, I like my screen, I only wished I knew exactly how hard or easy it would be to scratch.

Oh, and you can feel scratches with a pen, you can't with a finger. So there's that.

Re: Stantum's Multi-Touch resistive display
 

Somthing that would totally make me cream myself on the spot would be a screen where for at least each pixel there would be a distance sensor (kinda like Project Natal's camera but the imaging sensor instead of being a grid behind a lens it would be a grid the size (and resolution) of the screen laid on the screen itself)

Of course, also detecting multiple touch pressure with assorted materials like Stantum's would rock. Hell, since i'm dreaming high, gimme also one of those baterryless wireless Wacom stylus with 1024 levels of pressure sensitivity on the tip and two side buttons, popping out of the device itself like the N900's stylus.

Re: Stantum's Multi-Touch resistive display
 

its more accurate it can be used with std materials and the like. stantum has a real solution without the two touch limit. the idea is though that capacitive is better. there are no, zero techinical advantages to capcitive. ESPECIALLY in light on the higher res of these screens. the higher the pix.densith the more accurate a touch needs to be. you can order stantuns overlays and screen matrix, and chipset but no one has. i would ddef like to see this used over cap. i still dont know why everyone goes apeshit for cap.


ps: ive worked outside in my life i have rough hands and thick skin on my finger tips i have a handicap when it comes ro conductivity so i suppose im bias. hence why i pick hw keyboards and pressure sensitive ts screens. i got really lucky with the n900 and it seems to be as pinnacle of my needs tech wise as everyone has abandoned resistive.

i never saw a review stating why the n900 should have cap screen just a buncha of whining neophites complaining about something they dont know about. instead of using the screen and seeing how well it worked depite its percieved obsolesence.

i only expect them to learn english if they are going to live where english is the language...unfortunately in the USA, though you make that comment, there are areas i go to and they look at ME like,... Cant you just f'in learn to speak MY language!? lol


backwards.
ok now, back on subject.

Re: Stantum's Multi-Touch resistive display
 

Capacitive displays have several advantages:
* Better light passthrough. Without a matrix and embedded metal, a capacitive lets ~100% light through, whereas a resistive eats up to and around 50%. As a result, same image means more power consumption for a resistive.
* Forces one to use finger, which protects the surface. No hard pen means longer life. It's questionable, but there it is.
* Since there is no bending involved, the screens can be hard, which allows for harder materials. Glass is a lot tougher than soft, bendable plastic.
* Allows multitouch

Resistive has its advantages:
* Precision
* Allows pen and pointing devices, including handwriting, drawing, etc.
* Can be touched lightly without registering.

That being said, I want resistive for me. I tried capacitive and my finger is HUGE compared to a pen. Makes screens seem small. Even a 24 inch at the office is hard to use, because every now and then you need precision.
