14.2. LCD TV pixel faults
Despite the state-of-the-art produc-
tion methods, 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 reso-
lution of 1920 x 1080 (MD 30223
/ 30224) / 1366 x 768 (MD 30326
/ 30327) pixels, which are each
made up of three sub-pixels (red,
green, blue), there are a total of ap-
prox. 6.2 (MD 30223 / 30224) / 3,1
(MD 30326 / 30327) million con-
trol elements in use. Occasionally
pixels or individual sub-pixels can fail or become incorrectly controlled because of
this very high number of transistors and the extremely complex manufacturing pro-
cess 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 fault
class).
