A capacitive touchscreen panel is coated with a material, typically indium tin oxide that conducts a continuous electrical current across the sensor. The sensor therefore exhibits a precisely controlled field of stored electrons in both the horizontal and vertical axes - it achieves capacitance. The human body is also an electrical device which has stored electrons and therefore also exhibits capacitance. When the sensor's 'normal' capacitance field (its reference state) is altered by another capacitance field, i.e., someone's finger, electronic circuits located at each corner of the panel measure the resultant 'distortion' in the sine wave characteristics of the reference field and sends the information about the event to the controller for mathematical processing. Capacitive sensors can either be touched with a bare finger or with a conductive device being held by a bare hand. Capacitive touchscreens are not affected by outside elements and have high clarity. The Apple iPhone is an example of a product that uses capacitance touchscreen technology: the iPhone is further capable of multi-touch sensing.
Capacitive sensors work based on proximity, and do not have to be directly touched to be triggered. In most cases, direct contact to a conductive metal surface does not occur and the conductive sensor is separated from the user's body by an insulating glass or plastic layer. Devices with capacitive buttons intended to be touched by a finger can often be triggered by quickly waving the palm of the hand close to the surface without touching.
The HTC/T-Mobile G1/Dream is also equipped with a capacitive touch screen.
is the Xperia X1 also equipped with Capacitive touch screen? because i noticed its not as sensitive as iphone
Without opening up the phone, there are several ways to find out if a phone uses a capacitive or resistive (i.e. pressure-sensitive) screen.
1. Look at the screen off-angle in bright light. You may be able to see a grid of dots that looks something like this and extends over the entire screen surface:
. . .
. . .
. . .
If you can, it's probably not a capacitive screen.
2. Can the screen be operated by a non-conductive object i.e. a toothpick?
If so, it's probably not a capacitive screen.
3. Does the device come with a stylus/"plectrum" and does it require screen calibration?
If it does, it's probably not a capacitive screen.
No mass-market WM device to date has a capacitive touchscreen, including the X1. The first post of this thread will help you understand why: http://discuss.pocketnow.com/showthread.php?threadid=23389

My Xperia is more sensitive than an iPhone. Granted I did some tweaking, but still.
No, Xperia is like the rest of our phones has resistive screen. It can be very sensitive, but stylus will be your main indication. I have LG Prada that has capacitive screen and LG Viewty that has a resistive one.

Do capacititve screens have a separation issue like some of the HTC resistive screens have?
Where the layers of a resistive screen including the digitizer start to separate causing a rectangular shape in the center that looks like oil on water.
Has happened to me and many others where the screen eventually has a complete failure.
I do know that the capacitive screens on the iPhone are prone to breakage due to the fact that it has a glass surface.
The resistive screen of the Diamond is less prone to breakage because it has a plastic type film on the surface.
Btw, my screen is pretty sensitive, whether using the stylus or touch.
You can tweak your resistiv screen by allign screen.
If you dont press the screen and move little circles between the arrow you can make screen more sensitiv

Multi-touch
So.. I guess I'm going to show my ignorance, but here is my question.
There are several posts on several sites talking about how you can't do multi-touch unless you have a capacitive screen. Then I go to Pandawill and look at the G10. It says it's a resistive screen but there are videos of it doing pinch-to-zoom.
Can someone help me understand how multi-touch relates to the screen type?
Sorry if i'm too much of a n00b
Sorry to add fuel to fire but a capacitive screen will always be more sensitive (speaking purely about the physics of it) than a resisitive screen.
Why?
Capacitive screens rely on charge and comparative charge of two bodies. In some instances, capacitive screens can work without the finger actually touching the screen.
Resistive screens rely on a minute deflection from contact to connect two conductive layers. You can touch a resistive screen lightly enough to not result in a UI interaction. Resisitve screens can be tweaked to work at a very high sensitivity but still not as sensitive as a capacitive screen.
Go ahead, compare two phones with opposing screen tech side by side. I thought nothing could be as responsive as my Topaz till I bought a Nexus, then Desire (which have other issues btw! )
Sorry but thats the blunt science behind it. Bear in mind the perception of responsiveness to touch can very well depend on the quality/smoothness of the software written or the user interface.

Sorry for the double post but to answer your question,
Yes resistive screens can be used to provide multi touch support. Where this support isnt built into the drivers for the digitizer, its a lot harder. Bear in mind most older phones were launched before the mainstream advent of multi touch. Thus no drivers...only brilliant minds at XDA
However, using a resisitve touch screen to provide multi touch has some serious drawbacks, mainly on smaller screens.
I hate to break it to you but the reason behind this is actually the size of your "pinch" fingers with respect to screen size.
Multi touch on a small resistive screen cause deflection at multiple points on the digitizer but due to the reliance on deflection, the software will inevitably struggle to understand what sort of multitouch gesture you're trying to do! Your fingers with relation to screen size are simply too big!
When you have a bigger screen or a well designed digitizer + software, it can determine positions of multiple points much more accurately, thus allowing multi-touch.

Right.. I get that pinch is tougher on a small screen thats less sensative. The question was posed because there isn't a, what i consider to be cheap (in the 250$ or less range), 10 in capacative android tablet on the market.
If i venture in the the flatpad/apad/epad world... is it the case that it is impossible for that type of screen to do multi-touch? From your response I'm hearing that it IS possible to do multi-touch on a flatpad.. given that there are drivers supporting it. I'd love to have a capacative screen but from what i've seen online, they're going to be twice the cost or more.

A dilemma huh? To be brutally honest, most budget oriented tablets are simply that: budget oriented. A lot of them (im trying not to generalize) and Ive tried a fair few are poorly implemented tablets and more trouble than they are worth. Slow, laggy, bad battery life. You'll have enough issues to simply forget the lack of multi touch.
If I was after a tablet, hard as it may be, Id wait till some big players launch a proper device...that'll lead to better adoption and less half baked tablets that are more tech demo than retail product.
Bear in mind the lack of android market access on almost all of these tablets. Due to their generic nature, dev work is also a no-go. Everybody and their friends and family have a device out with a costomised, baked os that its not even funny!
Id check out the galaxy tablet from samsung or wait for it to make some waves and bring forth better implemented copycat products

I bought the Galaxy S yesterday, retiring my "aging" HTC Touch HD. I've never really used a capacitive touch display, so the sensitivity of the screen is very noticeable and surprising. It is so sensitive, infact, that I don't have to touch the screen for it to register my "touch". I noticed the same thing with a HP touchscreen computer I played with for a few minutes once, so is it normal for capacitive screens, or are some screens just (too) sensitive? Or am I just closer to an electric eel than the average person?

They are very very responsive compared to restitive touchscreens.
Yep, a resistive touchscreen requires that two layers are pressed together, so a definite press is required. Capacitive screens just need to detect an electrostatic field, so touching the screen itself isn't necessarily required.
I went from a touch hd to this too, and hell yeah its sensitive! Got used to it now tho.

I know the LG Optimus has a resistive touch screen, but is it possible to get muti touch by replacing original touchscreen to a glass touch screen and a new digitizer?
I cannot say it is impossible, because everything is possible. I think it is not worth
That's quite a big question, one problem that stands out is the odd shape of the GT540's screen, it doesn't stop as such where the screen stops, it stops before the real buttons, that would suggest to me that you'd have to have a custom screen and digitizer with those resistive buttons we have at the bottom (MENU, BACK) changed to capacitive, a custom screen would probably cost more than the phone itself. But if you do decide to waste a load of money outfitting a phone instead of buying a new one, on top of that you'd have to be able to program drivers for the display to work and you would have to modify your software that your phone runs top work with multi-touch.
So in short, really, no.
But if we had a load of developers (which we don't) what could be designed is a counter-point which isn't multi-touch in the traditional sense and is a software work-around, but still a bit of a waste of time.
I think is very strong to realize.
But i should be wonder
It's a very hard work... I don't think we'll have multitouch soon...
i will really want multitouch but think about it, its just cheaper and less time consuming to just get a new phone..
I am not permitted to post links, so search on youtube ''lg gt540 multi touch'' (without the quotes). First result is the one.
about the video:
This guy made a workaround for basic dualtouch. AFAIK and see one finger needs to be hold in place.
HI MrAndroid12
I think it's possible only if some one tweaks the kernel for recognizing multiple points
after replacing the resistive touch screen to capacitive one...
I would like to clear one thing to everyone who have an wrong notion about resistive touch screen..
A resistive touch screen can recognize a stylus or a small area of touch well
but a capacitive screen can recognize a larger area of touch like a finger..
and some resistive screen devices can multi touch..

Our GT540 has a really qualitative resistive screen, compared with others. And, yes, I really like using a stylus, for handwritten notes for example (I still miss my LG Cookie for that function).
It's true that capacitive screens have been advertized as better than resistive.
It is true,if you like responsiveness and the highest standards of all have been set by Apple in this field.
However, it is not ONLY responsiveness that matters in some cases, right?
It would be good if LG did
make lg gt540 multi-touch!!
sad...
Another issue to be aware of is the electronics to drive a capacitative screen are different to those for a resistive one. I think a lot more work would be involved beyond just drivers and actually finding a screen that would work.

Can't agree more. I just can't wait for my next phone
it's possible.. but it's very expensive..
i was looking on one device on the bestbuy store and when i was
deflecting the device i could notice the a matrix of spots/dots on screen
that never disappear only if i hold the device in some angle it would be not noticeable...
so i wanted to ask:
1. Am I the only one that saw that?!
2. if i will put a protect cover on screen it will make this dots/spots not seen?
Perfectly normal. The glass is supposed to be Gorilla, so I wouldn't even bother with a protector.
Sent from my Kindle Fire using xda premium
why is that normal ?
i haven't saw that on a PlayBook or a iPad or a Samsubg tab...
so why is this normal ?!
That's the grid for the capacitive touch sensor. On some devices it's more visible than others. I guess Amazon is using one of the more visible ones on the Fire.
Since this is bothering me very much, do you think if i would apply over it a protector it would be non-visible ?
Eh I can't see it on mine at all. Maybe It's just the display.

I doubt it, but you can try. FWIW, I can see the dots, but they only appear at an angle with certain glare on the screen. Doesn't bother me.
It's normal. You most likely noticed it due to light reflecting on it at a certain angle. My ipad had those, and my touchpad has them. I don't notice it unless the screen is off and its held at an off angle with a good amount of light reflecting off the surface. You don't notice it while it's on.
This was VERY visible on my Nexus One, but isn't on my Sensation. It's back on the Kindle, but you only notice it when.the screen is off. It depends on the display, and I think the more reflective the screen, the less you see.

It has both dots and also a grid matrix. You can see it on every one, just have to turn the unit *just so* to see it.
My understanding from a post on Amazon about the device is that its not a capacitve or resistive touch screen but an infrared touch screen.
Confirmed myself that it is not capacitive as you can touch it with anything and it responds, where my iphone and Captivate do not.
Food for thought. Has anyone else heard of an IR touchscreen before?
Ive always been able to see the dots on every touch device I've owned. Just requires the right angle and light.

Yeah, they're just rarely used, because the technology has only been reasonably cheap/simple for a few years (iirc), whereas capacitative and resistant touchscreens have been around for much, much longer.
Also, touching the screen with a pen lid doesn't do anything for me. You sure it works with *anything*? I got it to work with a piece of moleskin, though, so... maybe it's just certain things?

The Kindle with the IR touch screen is the Kindle Touch, which uses the IR touch screen because capacitive touch screens aren't available for the E-Ink screen yet. IR touch screens work by shooting IR lasers across the screen in a grid format, so a touch would trip IR lasers, and which lasers are tripped can be used to calculate where the touch is in. That's what they use on the Nook Simple Touch, too. I remember my old car built-in GPS was an IR touch screen. You could trick it by blocking the IR receivers.
Nowadays, most LED touch screens are capacitive, which is what's on the Kindle Fire (the reason why there's dots on the screen - I think they're the sensors that measure the capacitance to calculate the location of the touch).

The Note has an inductive display to support the S-Pen and the N10's display is capacitive and the pen won't work. So, pick one.
so the screens are not separated like a digitizer and the actual screen ?? and sorry for these question im ignorant when it comes to things like these.
Pretty sure the Exynos 4 that's inside the Note 10.1 doesn't support the Nexus 10's screen resolution. So it won't work as far as I know.
The screen wont work for mainly two reasons the wavecom chip wont work with a capacative screen and it does not support higher resolution then what we have on the note. That is why not has that resolution
The processor does not support that high resolution.
These are main two reason apart from many other. Its like fitting a trucks body on a cars chassies

Here's the difference between the two displays. An inductive display picks up an electro-magnetic signal from the pen where a capacitive display only can respond to physical contact. Based on the manufacturing complexity I'd guess the Note's display cost Samsung more than the FHD+ display on the N10.

Thank you guys , just using my imagination
I didnt know that the screen resolution mattered to the cpu , but then again a computer monitor will go as far as the graphics in a pc allows it ..
Yes the same concept works over here, it depends on how much the mali gpu allows it go to. Secondly as the resolution increase the processing power requirement also increases.
You can have insane resolutions but how pratical are they since most of the apps are developed for a 5inch screen.
This was posted in the N10 forum and sort of describes the challenges of inking on a capacitive display by someone who tried to solve them. To me, either inking works well or why bother. Using a kluge might get the job done but would be very frustrating. I'd rather live with the 720P display (which is still better in contrast and brightness than the N10's).

I made the app Writepad Stylus to do precisely that, on the Asus Transformer 101. Palm rejection on a capacitive screen, without weird zoning boxes. It worked pretty well and I made a lot of money from it. But there are a ton of issues with that algorithm that I ran into when I got the Asus Transformer Prime, which ultimately made me give up on the app:
Bad capacitive screen sensitivity. The Transformer Prime and the Galaxy Tab 10.1 both have awful sensitivity settings, so the writing comes out looking like an 8 year old's scribble. It doesn't register all the input points. It doesn't start recording points until AFTER you move the stylus a certain distance. Ugh. There's an app that sorta fixes that called TouchscreenTune, but it requires root, and the settings for that are really hard to calibrate. Even after messing with that, it's still not as good as on the Xoom or the original Transformer.
Touch screen can't handle straight lines. If you try to draw a straight line horizontally or vertically, it comes out straight. If you try to draw a diagonal line, it comes out wiggly. This is also particular to certain tablet screens. Who knows whether a particular tablet will have good touch screen or crappy one? No reviewer tests for that kind of thing. You have to go to the store to try it out.
Your hand will accidentally hit the notification or navigation buttons, taking focus away from the app, or accidentally going back to the homescreen. As far as I know, this can happen even with the S-pen. Asus has a "lock navigation bar" feature on their tablets, which is nice. There's no way to hide the navigation bar or disable it while something is going on in app (unless you root your tablet).
Anyway, if someone wants to test these things on the Nexus 10 and report back, I'd be grateful since I can't find these in stores yet. Just try to write as small as you can with a capacitive stylus, and try to slowly draw straight diagonal lines.

You have posted a comparison between a RESISTIVE display and a capacitive/inductive one. The top picture is resistive which is old technology now, it's what the old smart phones and pocket PC's used and had a thin layer of plasticky material for sensing pressure. The note 10.1 uses both capacitive (for fingers) and inductive (for the pen).....and the nexus 10 just uses capacitive, not the screen in the 1st pic in your diagram. As far as I know, no screens use resistive tech anymore.
