Close-up of an LCD, showing a dead green subpixel as a black rectangle. A defective pixel or a dead pixel is a pixel on a liquid crystal display (LCD) that is not functioning properly. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels, [1] while hardware companies tend to have further distinguishing ...
Three distinct types of defective pixels are described: Type 1 = a hot pixel (always on, being colour white) Type 2 = a dead pixel (always off, meaning black) Type 3 = a stuck pixel (one or more sub-pixels (red, blue or green) are always on or always off) The table below shows the maximum number of allowed defects (per type) per 1 million pixels.
The pixels on OLEDs inevitably lose their brightness over time. The longer an OLED pixel is used (illuminated), the dimmer it will appear next to a lesser-used pixel. [6] In the case of LCDs, the physics of burn-in are different than plasma and OLED, which develop burn-in from luminance degradation of the light-emitting pixels.
If you happened to watch Zack Snyder’s “Army of the Dead” this weekend, you might have noticed something was not quite right. You weren’t alone — quite a few Twitter and Reddit users ...

The Needham native has been stuck in space with Wilmore for the last seven months after problems with the Starliner concerned NASA and prompted them to keep them up there longer.
The form of dimetric projection commonly used in video games and pixel art. Only two of the angles separating the x, y and z axes are the same, and only some of the lengths of the cube's edges are equal. The expression arctan(sin(30°)) is equal to ≈26.565° and forms a 2:1 pixel ratio.
