LCDscreenNotes
High-quality TF T 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 (p icture elements) may be present. The maximum
permitted nu mber of pixels faults is stipulated in the internationa l 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 o f
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
subpixels, normally red, green a nd
blue. A pixel is the s
mallest element that can be g enerat ed
by complete functi
onality of the display.
Subpixel
A subpixel is a sep
arately addressable internal structure
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 operated with ba ckground 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 individu ally.
