what's a "capacitative" screen?

[ShaggyKids]

Just looking for a description of what a capacitative screen is, please?

Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, resistive type touchscreens require much more pressure to activate than capacitive touchscreen.

What’s the difference between Capacitive and Resistive?

A capacitive touchscreen measures the interaction between an electrical signal on a transparent grid above the screen and the user’s finger. A capacitive screen is beautifully smooth to operate because it just requires the presence of your finger, not any pressure. The flip side of this is that you can’t use a stylus. While a resistive touchscreen has two thin layers of conductive but transparent film above the screen, and measures the change in resistance between the two layers due to the pressure of touch. Resistive touchscreens are cheaper to make, but don’t support multi-touch. If the user presses with more than one finger the device can’t determine the position of the multiple fingers. A resistive screen can be made pressure-sensitive, so that applications may distinguish between a light and a heavy touch. A capacitive screen just knows “finger present” and “finger absent”.

Good thorough answer

And finger fat. The real downside of the c screens is for those of us who use spreadsheets and the like. Them leetle cells don't know which one's being touched by fingers. Styluses are great for it, and can even hold a pen on the other end! I miss that. I never have a pen now.

I've never really understood the technical part of this until reading Cyber Warrior's post. Thanks for the explanation.

... it gives you the 'capacity' to touch the screen
