LCDscreenNotes
High-quality LCD screens (TFT) are installed in notebooks from Fujitsu. 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 m onitor
resolution which differs from the spec ification can result in an unclear picture.
The screen resolution of the LCD monitor of your notebook is optimally set at the factory.
Current production technology cannot guarantee an absolutely fault-free screen display. A few
isolated constantly lit or unlit pixels may be p resent. 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 12 80 x 800 has 1280 x 800 = 102400 0 pixels. Each pixel consists of
three s ubpixels (red, green and blue), so there are almost 3 million subpixels 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 dark subpixels
or an equivalent mix (1 light subpixel counts as 2 dark subpixels) are allowed to be defective.
Pixel
A pixel consists of 3
subpixels, normally r ed, green and
blue. A pixel is the s
mallest element that can be generated
by comple te functi
onality of the display.
Subpixel
A subpixel is a sep
arately addressable internal structure
within a pixel tha
t enhances the pixel fun ction.
Cluster A cluster contains two or more defective pixels or
subpixels in a 5 x 5 pixel block.
Background li
ghting
TFT monitors a
re operated with backgro und lighting. The 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. T his
results in optimum reada bility and longer battery life at the same time.
