LCDscreenNotes
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TFT monitors are man ufactured 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 un clear picture.
The screen resolution of the LCD mon itor 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 stan dard 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 s ubpixe
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 p ixels or
subpixels in a 5 x 5 pixel block.
Background light ing
TFT monitors are operate
d with ba ckgro und lighting. The lum inosity of the background
lighting can decrease du
ring the period of use of the notebook. 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 ambient light sensor and depending on the respective light conditions.
This results in optimum readability and longer battery life at the same time.
