LCDscreenNotes
High-quality TFT displays are installed in notebooks from Fujitsu Technology Solutions GmbH. For
technical reasons, TFT monitors are manufacture d for a specific resolution. An optimal, clear
picture ca n only b e ensured with the correct resolution intended for the relevant TFT monitor. A
monitor resolution which differs from the specification can result in an unclear picture.
The screen re solution of the LCD monitor of your notebook is opt imally set at the factory.
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (picture 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 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 m ay be defective (1 ligh t subpixel counts as 2 dark subpixels).
Pixel
A pixel consists of 3 subpixe
ls, normally red, green and
blue. A pixel is th e 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.
Backgroun d lighting
TFT monitors are operate
d w ith background lighting. The luminosity of the background
lighting can decrease du
ring the period of use of the note book. However, you can
set the brightness of you
r monitor individually.
