Screen-door effect

（重定向自Screendoor）

The screen-door effect (SDE) or fixed-pattern noise (FPN) is a visual artifact of displays, where the fine lines separating pixels (or subpixels) become visible in the displayed image. This can be seen in digital projector images and regular displays under magnification or at close range, but the increases in display resolutions have made this much less significant. More recently, the screen door effect has been an issue with virtual reality headsets and other head-mounted displays, because these stretch a single display across a much wider field of view.
