Advice after touch screen no more work

[Bobarctor2000]

Hi,

The touch screen of my HTC elf doesn't work anymore.
I am going to order some parts to change the digitizer myself and also the casing to make it look a little newer.

Anyway, I'd like to understand how the touch functionality works exactly. Is it a pressure on the digitizer itself that make a "touch" or is it a pressure on the digitizer that press the screen and this action make a "touch" ?

When I power my disassemble Elf, a pressure on the screen itself doesn't do anything....

I'd like to know if I need to order a screen as well :)

Hi,
just replaced my own elf's digitizer a month ago... and the phone is like new.

To answer your question it's the digitizer that reads pressure and sends the data to the system (if you already disassembled it you should have noticed a flat cable that connects the digitizer to the board).
So if the screen on your elf is working you should solve the problem by replacing only the digitizer.
