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 international standard ISO 13406-2 (Class II).
Examples:
A 20" or 22" flat-screen monitor with a resolution of 1680 x 1050 has 1680 x 1050 =
1764000 pixels. Each pixel consists of three subpixels (red, green and blue), so there
are almost 5.3 million subpixels in total. In accordance with ISO 13406-2 (Class II),
a maximum of 6 pixels and 9 subpixels may be defective.
