Glass replacement or screen replacement?

You can change just the glass (if the problem is cracked glass, ofc), the colour of the phone does not matter, it's the same glass replacement for all of them.

Hi, I'm not quite sure if I need to replace my screen and digitiser or just the screen. My display has vertical coloured lines (as sometimes appear on laptop screens too) due to force from dropping the phone. Also, could you also clarify what the digitiser is, as I've heard about it but am not sure (I have previously replaces screens on laptops, but never came across the term).

Thank you
