LCDscreenNotes
High-quality LCD scre ens (TFT) are installed in note books from Fu jitsu. 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 m onitor. A monitor
resolution which differs from the specification can result in an unclear picture.
The screen resolution of the LCD mon itor of your notebook is optimally set at the factory.
Current production technology cannot guarantee a n absolutely fault-free screen display. A few
isolated constantly lit or u nlit pixels may be present. The maximum permitted numb er of such
faulty pixels is specified in the international standard ISO 9241-307 (Class II).
Example:
A screen with a resolution of 1280 x 800 has 1280 x 800 = 102400 0 pixels. Each pixel consists of
three subpixels (red, green and blue), so there are almost 3 million su bpixels in total. According to ISO
9241-307 (class II), a maximum of 2 light and 2 dark pixels and in addition 5 light or 10 da rk subpixels
or an equivalent mix (1 light subpixel counts as 2 d ark subpixels) are allowed to be defective.
Pixel
A pixel consists of 3
subpixels, normally red, green and
blue. A pixel is the s
mallest element that can be generated
by complete functi
onality of the display.
Subpixel
A s ubpixel is a sep
arately addressable internal structu re
within a pixel t ha
t enhances the pixel function.
Cluster A cluster contains two or m ore defective pixels or
subpixels in a 5 x 5 pixel b lock.
Background li
ghting
TFT monitors a
re ope rated with background lighting. T he luminosity of the background
lighting can
decrease during the period of use of the notebook. However, you can
set the brigh
tness of your monitor individually.

Ambient Light Sensor
In the case of delivery with a Windows operating system, the screen brightness is regulated
by means of the ambient light sensor and depending on the particular light conditions. This
results in optimum readability and longer battery life at the same time.
