It’s just a strip of black adhesive all the way around - not glue. Just warm it up with a heat gun or hair dryer and carefully peel apart the LCD and digitizer. That said, if you’re replacing a broken LCD it might be easier just to get the complete LCD+digitizer assembly (the digitizer is cheap).

Okay, I took the plunge and tried separating the LCD and digitizer - it worked! The trick is to use a heat gun to heat one end of the digitizer side and then very carefully and slowly bend/peel it back from the LCD. There is a thin frame (about 2 mm wide) of black adhesive that goes all the way around. Once you’ve pulled them apart you’ll need to peel off that adhesive strip and move it to the new digitizer (if that’s what you’re replacing). Reattach the digitizer to the Switch Lite frame (reuse or use new clear adhesive if necessary), and then carefully align and stick the LCD to the backside of the digitizer. Then just reassemble everything and you’re good to ho.

I agree with the posters above - it’s the most important and dangerous step (separating the screen from the digitizer) and they choose to go with “something magic happens here”! Disappointing and frustrating.

Why are there NO videos or howtos that show the trick in separating the digitizer from the LCD? I’ve disassembled everything but I’m stuck at that point. My LCD is good - just the digitizer is scratched and I don’t want to crack the LCD separating it from the digitizer. What’s the trick? Just a heat gun and careful prying? Note the Switch is different from the Lite - in the Switch the LCD and digitizer are not glued together, so it’s simple to replace just one. Not in the Lite tho. Any suggestions?
