Working with the notebook LCD screen LNCoDtescreen High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For technical reasons, TFT monitors are manufactured for a specific resolution. An optimal, clear picture can only be ensured with the correct resolution intended for the relevant TFT monitor. A monitor resolution which differs from the specification can result in an unclear picture. The screen resolution of the LCD monitor of your notebook is optimally set at the factory. The standard of production techniques today cannot guarantee an absolutely fault-free screen display. A few isolated constant lit or unlit pixels (picture elements) may be present. The maximum permitted number of pixels faults is stipulated in the international standard ISO 9241-3 (Class II). Example: A monitor with a resolution of 1280 x 800 has 1280 x 800 = 1024000 pixels. Each pixel consists of three subpixels (red, green and blue), so there are almost 3 million subpixels in total. According to ISO 9241-3 (class II), a maximum of 2 light and 2 dark pixels and an additional 5 light or 10 dark subpixels or a corresponding mix may be defective (1 light subpixel counts as 2 dark subpixels). Pixel Subpixel Cluster 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. A subpixel is a separately addressable internal structure within a pixel that enhances the pixel function. A cluster contains two or more defective pixels or subpixels in a 5 x 5 pixel block. Background lighting TFT monitors are operated with background lighting. The luminosity of the background lighting can decrease during the period of use of the notebook. However, you can set the brightness of your monitor individually.

Working with the notebook
LCD screen
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TFT monitors are manufactured for a speci
fi
c resolution. An optimal, clear
picture can only be ensured with the correct resolution intended for the relevant TFT monitor. A
monitor resolution which differs from the speci
fi
cation can result in an unclear picture.
The screen resolution of the LCD monitor of your notebook is optimally set at the factory.
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (picture elements) may be present. The maximum
permitted number of pixels faults is stipulated in the international standard ISO 9241-3 (Class II).
Example:
A monitor with a resolution of 1280 x 800 has 1280 x 800 = 1024000 pixels. Each pixel consists of
three subpixels (red, green and blue), so there are almost 3 million subpixels in total. According to
ISO 9241-3 (class II), a maximum of 2 light and 2 dark pixels and an additional 5 light or 10 dark
subpixels or a corresponding mix may be defective (1 light subpixel counts as 2 dark 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
A cluster contains two or more defective pixels or
subpixels in a 5 x 5 pixel block.
Background lighting
TFT monitors are operated with background lighting. The luminosity of the background
lighting can decrease during the period of use of the notebook. However, you can
set the brightness of your monitor individually.
