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" or 18" 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, i.
e. a total of 25 faulted dots. This corresponds to
approx. 0.0006 % of the entire screen surface!
