15.1. Full HD Caravan TV pixel faults
Despite the most modern produc-
tion methods, the highly complex
technology involved in produc-
ing this type of device means there
may be individual or multiple pixel
drop-outs (dead pixels). This is rare,
however.
For active matrix TFTs with a reso-
lution of
1920 x 1080
pixels, which
are each made up of three sub-pix-
els (red, green, blue), there are a to-
tal of approx.
6.2
Mio. control ele-
ments in use. Occasionally one or
more pixels can fail or become in-
correctly controlled because of this very high number of transistors and the associ-
ated extremely 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).
