Notes regarding the DIN EN ISO 13406-2 standard
Permanently unlit or lit pixels
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (picture elements) may be present. The maximum
permitted number of pixels faults is stipulated in the stringent international standard ISO 13406-2
(Class II).
Example:
A 17" or 19" flat-screen monitor with a resolution of 1280 x 1024 has 1280 x 1024 = 1310720 pixels.
Each pixel consists of three subpixels (red, green and blue), so there are almost 4 million subpixels
in total. In accordance with ISO 13406-2 (Class II), a maximum of 6 pixels and 7 subpixels may be
faulty.

Pixel
A pixel consists of 3 subpixels, normally red, green and blue. A
pixel is the smallest element that can be generated by complete
functionality of the display.

functionality of the display.
Subpixel
A subpixel is a separately addressable internal structure within a
pixel that enhances the pixel function.

Cluster
A cluster contains two or more defective pixels or subpixels in a
5 x 5 pixel block.
