Dark sub-pixels
(sometimes called off-pixels, stuck-off, or black
pixels) are characterized by the appearance of dark
pixels in white, red, green, or blue full-screen
picture.
Combined sub-pixel
defects are characterized by at least two sub-pixels
defects (bright or dim) being closer than 5 mm to
each other.
Temporal sub-pixels
(sometimes called blinking defects) exhibit
temporal variations not related to any steady-state
video input. Temporal sub-pixel defects may be
intermittent, exhibit a sudden change of state, or
be flickering.
