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, occasionally 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 complicated and varied from one manufacturer to the next. When handling warranty 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 defects. 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
