Touch screen is the best User-Input method for any device. Currently Every kind of gadget uses a touchscreen, from cell-phones to laptops. Today when you go to the market, you are offered 2 types of touchscreens
(i)Resistive
(ii)Capacitive
The biggest mystery for a non-geek wanting to buy a phone!!
Resistive touchscreens are considered inferior as, first thing they are cheaper as well as when you use it, it feels that it tends to miss your touch input. But actually you have to press it a little harder to make it work. And thats why we like capacitive touch screens more. The basic mechanism of the working of a resistive touch screen is that it uses two conductive layers with a very small gap between them. They upper layer is coated on the inside and the lower layer is coated on the upper side with a conductive material. Now we need to press the upper layer to cover this gap. There is a current flowing in the layer that is disturbed by the joining of the layers. This is how the touch is detected in a resistive touch screen. The scope of resistive touchscreens is huge in Industries, restaurants etc. For the reason that it is spill proof and you can use it with gloves as is the case in many industries.
Capacitive touchscreens are all the more expensive. But why we agree to spill more moola from our pockets is that it feels a lot better, coz you dont have to push down an elastic layer down the gap. It is more responsive!!
A capacitive touchscreen works on the principle that human body is a conductor. An insulator like a glass is coated with a conductive material on one or both sides forming a capacitor. Now when we touch on one side of this screen(capacitor) the value of capacitance changes and thus the touch is detected. But it cannot be used with gloves and also require a special stylys.
Another big technology advancement that happened was the multi-touch (or the mutual capacitance). It uses a grid of capacitors that can detect multiple touch on the same screen. Its like many small screens are joined together that can function individually. This with corresponding software developments have enabled us to detect gestures, for example the most common pinch gesture to zoom in or out. Now with more advancements we can also detect changes in pressure with which we press the screen.
You might have guessed that the whole capacitive phenomena completely resembles the touchscreen of an iphone or ipad. Yes, Apple has the most developed touchscreen with the desired software helping to enhance the experience further!!
So enjoy
