Stuck pixels are a fault that can be found on LCD televisions. The liquid crystal shutters normally open and close to pass varying amount of light through the panel. Every shutter should operate independently and change from fully open to fully closed.

A stuck pixel is the result of a shutter that is stuck in an open or closed position. If it is open, a bright red, green or blue dot will be seen. If it closed, then it will show up on lighter images as a dark colored dot.

Stuck pixels are very rare in the latest screens although they are still found from time to time.
