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 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"/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 dots
in total. According to ISO 13406-2 (Class II), a maximum of 6 pixels and 7 subpixels may be
defective.
A 20" flat-screen monitor with a resolution of 1600 x 1280 has 1600 x 1200 = 1920000 pixels. Each
pixel consists of three subpixels (red, green and blue), so there are almost 6 million dots in total.
According to ISO 13406-2 (Class II), a maximum of 8 pixels and 10 subpixels may be defective.
