5 Pixel
For active matrix TFTs with a resolution of 1920 x 1080 pixels, each of which
consist of three sub-pixels (red, green, blue), there are a total of approx. 6,2
million control transistors in use. Due to this very high number of transistors
and the associated extremely complex manufacturing processes used, occa-
sionally one or more pixels can fail or become incorrectly controlled.
In the past, there were a number of approaches for defining the permitted
number of pixel defects. However, these approaches were mostly very compli-
cated and varied from one manufacturer to the next. When handling warran-
ty issues for all of its display products, MEDION therefore adheres to the strict
and transparent requirements of the standard ISO 9241-307, Class II; which
has been briefly summarised below.
The ISO standard ISO 9241-307 defines, amongst other things, the generally applicable guidelines relating to pixel de-
fects. Pixel defects are categorised into four fault classes and three defect types. Every individual pixel consists of three
sub-pixels, each of which is assigned a basic colour (red, green, blue).
Pixel fault class Defect type 1
Continuously lit pixel
Defect type 2
Continuously black

The table describes the maximum number of pixel failures allowed on the screen, before a warranty claim arises. A war-
ranty claim may be applicable if the above number of defects in a category is exceeded.
