Stripes and afterimage on the screen, what could be wrong?

Question

macbook

Hello! MacBook Pro 13'', A1708. Black and white stripes appeared on the matrix and the afterimage disappears when the top cover is covered, and the afterimage too, but the fragment from the last photo remains static, almost imperceptible white stripes (sometimes blinking) also remain, and black stripes return when opened.
A week before the malfunction appeared, it received a crack at the time of wiping the screen, the pressing force was weak, so I assumed that the crack was formed due to voids. The whole week worked fine, there were no warnings.

Answer 2

>>> s = '123456789'

>>> from textwrap import wrap
>>> wrap(s, 3)
['123', '456', '789']

>>> map(''.join, zip(*[iter(s)]*3))
['123', '456', '789']
