Dead pixels spreading

[reapersweep]

I have an HP Pavilion x360 laptop. About a month ago, I bumped my laptop and a small cluster of stuck pixels appeared. After a few failed attempts at trying to fix the stuck pixels, I gave up and decided to just live with it when a few days later I noticed the pixels had turned black.
Since then, the dead pixels have slowly been growing despite and I'm not sure what's causing it or how to stop it. I'm also poor and can't simply replace it.

Internal damage to the display. The only fix is to have the display replaced.
