The thin layer technology of the capacitive touch screen allows for a sharper picture than other touch screens. Also, since the capacitive touch screen is responsive to human touch but not most other objects, accidental touches are less of a problem.

What are the two types of touch screen mobile technology available in market?
capacitive touch screen like the iphone and most phones resistive touch screen like some nokia touch mobiles capacitive is much better and smoother
What is a capacitive touch screen?
In fact, the capacitive touch screen has a capacitive system. It is built with a layer that holds an electrical charge right on top of the glass panel. When a finger touches the screen, some of the charge escapes into the finger. The decrease in charge is measured in circuits which are usually located at the corners of the screen. And from the relative change in charge at each corner the computer can calculate what the point of contact was with the finger that released some of the charge. http://www.dinodirect.com/Cell-Phones/Cell-Phone-Accessories
Does a tablet PC come with a stylus?
Some do, the main one being the HTC Flyer. There is recent technology buy Samsung which is a small stylus that works on capacititive touch screens. Pretty much anything works on a resistive touch screen. But yes, anything that has a resistive touch screen usually come with a stylus. With capacitive touch screen tablets, no they do not have styluses.
Is there any hardware needed to make a PC touch screen?
One would have a difficult time building their own touch screen.There are a few different touch screen technologies out there. The first (and usually most rugged) is an infrared "grid" that covers the screen. Touching the screen breaks the beams, and that is translated into x and y coordinates.The more common method is a resistive film that covers the screen. The film has microscopic wires going through it, and when you touch the screen, the wires are shorted together, once again giving x and y coordinates.A third type (used in the iPhone) is a capacitive touch screen. These are very rugged, however they can't be activated with, say, a pencil eraser like the resistive film.In the capacitive system, a layer that stores an electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases.
How do touch-screen I-Pods work?
There are three different types of touch screens. Resistive, Capacitive, and Surface Acoustic Waves. The iPhone and iPod Touch use Capacitive method. The device contains a capacitive layer that stores the electrical charge. When a user touches the screen, the number of currents in that particular spot decreases because some of the currents are being deposited to the finger. The iPod/iPhone detects this change and the information is transferred the OS for analysis. After the device registers the touch, the data is captured and observed. The points where there was the most pressure are defined and the touch is more accurate. This information is sent to the operating system once more, and the action of button is performed. Of course, this happens instantaneously. The iPod Touch revolutionizes touch screen like never before, because multiple points can be recognized at one time, and many other touch screens cannot do that yet.
How does touchscreen work?
There are two main technologies for touch screens these days: resistive and capacitive. Resistive touch screens work by pressing a sheet of plastic against a conductive material underneath and recording the position at which this occurred. Capacitive touch screens work by having a layer that stores electrical charge on top of a sheet of glass, and recording when some of the energy from the glass is transferred to the user. Touch Screens work by having a thin overlay on top of the actual display. This overlay is a sensitive layer which transmits an electrical signal. The computing components then use this data to identify where the user has touched on the screen.
Is the sidekick touch screen?
No : the sidekick 3 is not a touch screen phone. -MyCellz4Less
What are Vaio computers and do they have touch screen?
Vaio computers is a company that sells high quality computers. Yes, some are touch screen, but not all of them. Some desktops are touch screen (big desktops).
What is the difference between capacitive and resistant touch screens?
TFT (Thin Film Transistor) is a type of LCD display and is not related to touchscreen technology in any way; a better question would be, "What is the difference between resistive touchscreens and capacitive touchscreens?"Resistive screens are an older design, in which two electrically conductive layers are separated by an insulating gap. When pressure is applied, the resistance between the layers changes at that point. While cheap and reasonably durable, they require styluses, don't support multi-touch and can reduce the quality of the displayed image.Resistive screens were used in the original Palm Pilot and later Palm devices, in some portable games like the Nintendo DS, and in some current applications where their low price outweighs their limitations.Capacitive touchscreens use newer technology that also relies on electrical conduction, but senses changes in capacitance rather than resistance. Since human skin conducts electricity, moving a finger near the electrostatic field of a capacitive touchscreen will change the field, and the change can be measured and interpreted as a touch. Although they can be triggered by metallic objects, cloth, and other materials and are more expensive than resistive sensors, capacitive screens don't require syluses, support multi-touch, and can be made perfectly transparent.Capacitive screens are used in many new smartphones and tablets, including the iPhone, iPad, the Droid Incredible, Blackberry Storm, etc. The iPod trackwheel is an example of this technology used without a display.
