Touch Screen Solutions
How does the touch screen work on the Blackberry Torch?
Is it warmth? Static electricity? Other…?
I have a bet going about how it works, but can’t find the answer anywhere. A reference to your solution would be great.
Thanks!
Touch screen phones have two layers, the LCD screen and the Digitizer. The Digitizer is being used by all the big companies right now, BlackBerry, Android (HTC/Samsung) and iPhone’s.
Your answer of static electricity is the best answer from your friends. When you touch the Digitizer it turns the analog input into digital info. Think of it as a electricity grid across the screen and as soon you touch it you put a break in the digital signal. The phone then figures out where on the grid you touched and if there was any movement upon touch. It all happens really fast in the hardware of the phone.
This forum post can also help explain it as well.

I learnt this from repairing phones, you need to purchase the LCD and the Digitizer for it to work.
