20. European Norm EN 9241-307

Class II

There have been several attempts in the past to define

the acceptable number of defective pixels. But this can be

difficult and varies widely between different

manufacturers.

We, therefore, adhere to the clear and strict requirements

of EN 9241-307,

class II, for the warranty handling of all LCD display

products. These requirements are summarised below.

Within standard EN 9241-307the 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).
