Colour monitor B15-1

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 15" flat-screen monitor with a
resolution of 1024 x 768 has 1024 x 768 =
786432 pixels. Each pixel consists of three
subpixels (red, green and blue), so there are
about 2.4 million dots in total.
According to ISO 13406-2 (Class II), a maximum
of 4 pixels and 5 subpixels may be defective, i.
e. a total of 17 faulted dots. This corresponds to
approx. 0,002% of the entire screen surface!
