Pixel errors in the TFT monitor
A total of approx. 4.3 m control transistors are used in the case of Active Matrix TFTs with
a resolution of 1600 x 900 pixels , each composed of three sub-pixels (red, green, blue). A
failure or incorrect control of pixels or individual sub-pixels can arise occasionally, because
of this very high number of transistors and the extremely complex manufacturing process
associated with it.
There have been continuous approaches to define the number of permitted pixel errors in
the past. However, these attempts have for the most part been very complicated and
completely different from manufacturer to manufacturer. MEDION follows the strict and
transparent requirement of the
ISO 9241-307, Class II Norm, which are summarised in
brief in the following, in the handling of guarantees for all TFT display products for this
reason.
Among other matters, the 9241-307
ISO Standard defines generally ap-
plicable guidelines in relation to pixel
errors. The pixel errors are catego-
rised into four error classes and three
types of error. Each individual pixel is
composed in its turn of three sub-
pixels each with a basic colour (red,
green, blue).
