Dead pixels are mostly black (sometimes white). Paralyzed pixels are usually bright, or in two, or possibly in all three primary colors!
Sub-pixels are fully illuminated. If the pixel in question is white, both are possible.
A dead pixel
is when the pixel is always off. It's easiest to spot a dead pixel against a white background. The pixel does not seem to be there. Dark, so paralyzed pixels. A hot pixel is when the pixel is always on. It's easiest to see against a dark background. The pixel is bright white.
A stuck / paralyzed pixel
is usually red, green, blue, or yellow, but may also be a light black color.
