Smart Tv Pixel Faults - Medion LIFE P15052 Manual De Instrucciones

13.2. Smart TV pixel faults

Despite the state-of-the-art production meth-
ods, in rare cases there may be individual or
multiple pixel drop-outs (dead pixels) due to
the highly complex technology.
For active matrix TFTs with a resolution of
3,840 x 2,160 pixels, which are each made
up of three sub-pixels (red, green, blue), there
are a total of approx. 24.9 million control ele-
ments in use. Occasionally pixels or individual
sub-pixels can fail or become incorrectly con-
trolled because of this very high number of
transistors and the extremely complex manu-
facturing process used in this context.

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 defect
