LCDscreenNotes
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TFT monitors are manufacture d 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 m onitor 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 e lements) m ay 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. E ach pixel consists of
three subpixe ls (red, green and blue), so there are almost 3 million subpixels in total. Acco rding to
ISO 9241 -3 (class II), a maximum of 2 light an d 2 dark pixels and an additional 5 light or 10 dark
subpixels or a corresponding mix may be defective (1 light s ubpixel co unts as 2 dark s ubpixels).
Pixel
A pixel consists of 3 subpixe
ls, 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 a
ddressable internal structure
within a pixel that enhance
s the pixel function.
Cluster A cluster contains two or more defective pixels or
subpixels in a 5 x 5 pixel block.
Backgroun d lighting
TFT monitors are operate
d w ith background lighting. The luminosity of the background
lighting can decrease du
ring the period of use of the note book. However, you can
set the brightness of you
r monitor individually.

Ambient light sensor
If your notebook was shipped with the Windows 7 operating system, the screen brightness is
regulated by means of the amb ient light sensor and depending on the respective light conditions.
This results in optimum readability and longer battery life at the s ame time.
