Screen turns slowly white after replacement [pictures]

Hello, this is my second replacement, after one screen broken and now a cheap replacement screen.

Anyway, the screen started doing ghost touches, because the glass was separating. A few black bars appeared at the top and vertical lines on the sides.

I got an original screen from another iPhone and when I connected the screen same bars appear only this time smaller, but this time when I clic the wake up button, the screen starts to turn kind of pixelate like low resolution, with unsharp lines in the icons, the battery icon even looks like cropped from the bottom. Everytime I wake up the phone the screen is normal, but goes fuzzy and turns slowly white again.

When I placed the old cheap screen on the other iPhone the same bars appeared on this damaged screen, similar to the ones on the new screen.

Could it be static electricity? seems weird it is happening to both screen when one is damaged and the other one is functional and original.

By the way, the touch works perfectly, no ghost touches or anything. Fully functional
