how do they work? like the ones you may find in department stores that have those self serve checkouts (which will have a touchscreen)... how does the touch screen actually work? is it the weight of the persons finger or the mere contact with the skins surface?
this is for something important btw
...desperate for husnul-khitaam...
please make dua that Allah grants me a good end (to my life). please make dua that Allah guides me.

sister there are two types of touchscreens
A capacitive screen and a resistive screen
the resistive screen relies on pressure....so it only works when you push your finger on it to register an input hence the name 'resistive', it has two layers which are close to each other so when you press hard enough on the surface of the first layer it will touch the second layer which is electronic,...and so the electronic layer will activate things for example if you touched 'web browser' on the screen the second layer is responsible for making the phone/microprocessor know that it needs to open 'web browser'...its like getting a plastic bag and putting it on top of your house telephone when you press the plastic bag hard enough you can dial the numbers....the resistive screen concept is similar to this ( crap example ) .
the capacitive screen is very different from the resistive one because it uses glass that is covered with a thin conductive layer which is heat sensitive so when you brush your finger across the screen it senses the warmth of your finger...it then says to the phone/microprocessor a warm finger touched me and this is the certain application they want to view .....so you dont have to press hard like the resistive screen
which is better...the capacitive is more durable its made from glass and its more accurate..compared to the resistive one which you have to press hard all day just to register an input.
I hope that helps....i've taken out time to write this up...i might be wrong in some areas but someone else will correct me insha'Allah
if you are buying a mobile phone try to buy one that has a capacitive screen like the iphone or the HTC hero..but if you can't afford it buy the cheaper resistive screen...i've got a resistive one and Alhamdulilah it does the job
I've just received a fresh infraction from the mods and i've just realized that i have accumulated 9 infractions in total....and so its high time i cut out the crap and actually be useful to others

Our monitor is touch screen. it's cool, but can be very annoying when you see a little hand sneaking up behind you and touching the x button just so the owner of that hand can play games because they've now closed what you were doing.
