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).
Examples:
A 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
(1680 x 1050).
In accordance with ISO 13406-2 (Class II), a maximum of 7 pixels and 10 subpixels
(1680 x 1050).
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.
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.
