LCDscreenNotes
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TFT monitors are m an ufactured for a s pecific resolution. An optimal, clear
picture can on ly be ensured with the correct resolution intended for the relevant TF T monitor. A
monitor resolution wh ich differs from the specifica tion can result in an unclear picture.
The screen resolutio n of the LCD mon itor of your notebook is optimally set at the factory.
The standard of production techniques today ca nnot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (picture elements) may be present. The maximum
permitted nu mber of pixels faults is stipulated in the international standard ISO 9241-3 (Class II).
Example:
A monitor w ith 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 subpixe
ls, normally red, green a nd
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.
Background lighting
TFT monitors are operate
d with ba ckgro und lighting. The luminosity of th e background
lighting can decrease du
ring the period of use of the notebook. However, you c an
set the brightness of y ou
r monitor individually.
