ISO 13406-2 Class II

Active matrix LCDs (TFT) with a resolution of 1920 x 1080 pixels which are in turn com-

posed 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 defective

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

summarised 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).
