Type 1: Continuous lighting pixel (a bright, white dot), even when
it should not light.
Type 2: Non-lighting pixel (a dark or black dot) even when it
should light.
Type 3: Abnormal or defective sub-pixels of the basic colours
(e.g. steady lighting with half intensity, non-lighting of a
specific colour, blinking or flickering, but not included in
Type 1 or Type 2).
Furthermore, a so-called cluster (a matrix of 5x5 pixel) may contain
a limited number of erroneous pixel only.
For Error Class II, for each 1 million pixel only 2 pixel may contain
errors of Type 1, Type 2 and Cluster; it may present up to 5
erroneous pixels of Type 3 (see the following table).
