Information on LCD screen
LCDscreen: Notes:
High-quality TFT displays with especially bright background lighting are installed in
notebooks from Fujitsu Siemens Computers GmbH. For technical reasons, TFT monitors
are manufactured for a speci
fi c resolution. An optimal, clear picture can only be ensured
in the resolution intended for the particular TFT monitor. A monitor resolution which
differs from the speci
fi cation can result in an unclear picture.
The monitor resolution is understood to be the number of horizontal and vertical pixels (i.e. picture
elements) which make up the monitor display. For example, "UXGA" stands for 1600 x 1200
pixels. Each pixel consists of three so-called subpixels of the colours red, green and blue.
As a result, a UXGA monitor consists of 1600 x 1200 x 3 = 5.760.000 subpixels.

The correct screen resolution for your notebook can be found under "Technical Data" in the EasyGuide.
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 strict international standard ISO 13406-2 (Class II).
Example:
A 15" LCD 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 almost 2.4 million subpixels 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 defective subpixels. That is approx. 0.0007 % of the entire set of subpixels!
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 (= group of faults) A cluster contains two or more defective pixels or subpixels in a 5 x 5
pixel block.
