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 750×1334 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:
