ISO 13406-2 Class II

Active matrix LCDs (TFT) with a resolution of 1920 x 1080 pixels which are in turn
composed of three sub-pixels each (red, green, blue), contain about
6.2 million addressable transistors. Because of this very high number of transistors and
their extremely complex production process occasionally defective or incorrectly ad-
dressed pixels or sub-pixels may occur.
There have been several attempts in the past to define the acceptable number of defec-
tive pixels. But this can be difficult and varies widely between different manufacturers.
We, therefore, adhere to the clear and strict requirements of ISO 13406-2,
class II, for the warranty handling of all TFT display products. These requirements are
summarized below.
Within ISO-standard 13406-2 the general requirements regarding pixel defects are
defined. Pixel defects are classified into three failure types and four failure classes. Each
individual pixel is made up of three sub-pixels in the primary colours (red, green, blue).
