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 types.
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.
Dead pixel policies are often hotly debated between manufacturers and customers. To regulate the acceptability of defects and to protect the end user, ISO released the ISO 13406-2 standard, which was made obsolete in 2008 with the release of ISO 9241 , specifically ISO-9241-302, 303, 305, 307:2008 pixel defects.
