Stuck sub-pixel

A pixel on an LCD that remains perpetually "on".

A stuck sub-pixel is a pixel that is always "on". This is usually caused by a transistor that is not getting any power and is therefore continuously allowing light at that point to pass through to the RGB layer. This means that any given pixel will stay red, blue, or green, and will not change when attempting to display an image. These pixels may only show up using certain applications, or they may be on all of the time.
