Faulty pixels in display
A minimum number of faulty pixels in the display cannot be avoided. The following
is permissible:
Pixel number
Permanently light and permanently dark pixels
≤

Permanently light green pixels

The production process for modern flat screens (LCD) does not currently
guarantee that all pixels in the screen are error free. As long as it is not a case of
an accumulation of locally erroneous pixels, there are no relevant functional
restrictions.
