I got the same problem. MacBook Pro 15'' TouchId (2018)
My display cracked "out of the blue" when it was closed.
I was on my desk, MacBook closed on external display. Suddenly the external display went black. I checked to MacBooks Power (because that's the only reason I know why it could disconnect the display) - but nothing. All fine.
I opened the MacBook and I just saw some kind of bluescreen (like windows did) - but more or less a bluescreen with some snowflakes on it - not completely blue. This was all over the internal display.
I shut down the MacBook (hardware button)
I restarted.
I was surprised to see a tiny crack at the bottom right of the display and some colorful lines on the right side.
I didn't disappear after restarting.
Then I shut down again and lifted it up to make some more pictures of it while powered of (there was nothing to see on the display or on the keyboard or at the case)
Then I put it on the desk again, powered on and: .... **** - even more cracks!
It worked a while, but now the screen is completely black and doesn't work at all.
It's still working perfectly when it's connected to an external screen, but still...
It's so strange! And do not have to mention that I am very, very careful with my MacBook. It's THE thing I earn money with and 99% of my work is done on a desk with external screen and closed MacBook. So I do not carry it around a lot, don't open/close it very often.
Luckily I could convince a guy at an Apple Store that this is a true story and they will do it on warranty!
Maybe it helps some of you to have another one here who got the same problem.
Some words for google: Cracks on MacBook without physical impact. Cracked Screen while closed.
Directly after bluescreen and hard shutdown
