my phone fell out of my pocket face down onto the street a while ago. a few pixels died in patches, then a few in the center of the patch started working, and a couple lines of dead pixels worked their way across my screen. the touchscreen works fine, and although the glass is a tad scratched i don't feel it needs to be replaced. i want to fix it, but i am unsure if i need to buy just the LCD, or the LCD and digitizer? would this work? LCD screen or do i need something like this? LCD screen + digitizer many thanks.
