A dead pixel is permanently off and appears as a black dot due to a failure to receive power. A stuck pixel remains illuminated with a single color because its transistors are locked in an 'on' state. Identifying the difference is important for repair or replacement strategies.

Key facts

Dead pixels appear as small black dots and are permanently off because their transistors fail to receive power.
Stuck pixels remain illuminated with a single color, such as red, green, or blue, or a combination.
Stuck pixels occur when transistors are locked in an 'on' state, preventing them from displaying other colors or turning off.
Identifying the specific type of pixel defect is key for repair or replacement strategies.
Consumers use visual inspection and specialized test patterns to differentiate between dead and stuck pixels.
