LCDscreenNotes
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 w ith the correct resolution intended fo r the relevant TF T 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 tod ay cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (p icture 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 reso lution 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 to tal. 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 ma y be defective (1 light subpixel coun ts as 2 dark subpixels).
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 more defective pixels or
subpixels in a 5 x 5 pixel block.
Background li
ghting
TFT monitors a
re ope rated with background 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.
