So, any chance to get this for X220 tablet? How many touch points will the modded display have, if it's possible?
Probably no. Replacing the LCD is too tricky, because it's glued to the protective glass.
Do you have the outdoor viewing screen with gorilla glass, or the multitouch display?
I opened up my X220 tablet's screen (multi touch), and it wasn't glued to the front touch digitizer (not even sure its glass). it was just attached with some double-sided adhesive tape along the sides. I'm guessing you must have gotten the gorilla glass one then?
The wacom pen digitizer film was attached adhesively to the back of the screen, and the metal screen backing was cut out nearly to the edges of the screen, so that the signal could get through. I guess either a screen without metal backing or a modification to a screen to cut out or remove the metal would be needed.
I'm interested in upgrading mine to QHD, and would purchase a kit for that if you make a QHD version for the x220 tablet
