If you switch from a high
-
contrast
display (for example black lines/
characters on a white background)
to a picture of medium brightness,
you may be able to see a faint
image of the previous display for a
time. This phenomenon is not due
to a monitor defect but to the
technology used (IPS display with
large viewing angle, IPS = In Plane
Switching).
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!
