It looks like a prank wallpaper, an animated broken LCD wallpaper which designed for Apple iPhone 7. The display looks like a LCD broken with abstract lines and several dark spots. LCD (Liquid-Crystal Display) is a technology in display devices. If the device is broken, there should be several dark spot on it.
The resolution of this wallpaper is 750x1334 pixels. This resolution is the same with the official Apple iPhone 7 and iPhone 6s resolution. I have huge collection picture of broken screen wallpaper, this animated broken LCD is the #12 of all 49 broken screen wallpapers. Feel free to download all of them on below gallery:
