15.2. Smart TV pixel faults
Despite the most modern production methods, in rare cases there may
be individual or multiple pixel drop-outs (dead pixels) due to the high-
ly complex technology.
For active matrix TFTs with a resolution of 1,920 x 1,080 pixels, which
are each made up of three sub-pixels (red, green, blue), there are a to-
tal of approx. 6.2 million control elements in use. Occasionally pixels
or individual sub-pixels can fail or become incorrectly controlled be-
cause of this very high number of transistors and the associated ex-
tremely complex manufacturing processes used.

The permitted number of defects for every type named above in each class of pixel defect refers to one million pixels
and must be converted accordingly to match the physical resolution of the display.
Your device complies with the European ISO 9241-307 Class II standard (pixel fault class).
