LCDscreenNotes
High-quality LCD scre ens (TFT) are installed in note books from Fu jitsu. For technical reasons,
TFT monitors are manufactured for a specific resolution. An optimal, clear picture can only
be ensured with the correct resolution intended for the relevant TFT m onitor. A monitor
resolution which differs from the specification can result in an unclear picture.
The screen r esolution of the LCD screen of your notebook is optimally set at the fact ory.
Current production technology cannot guarantee a n absolutely fault-free screen display. A few
isolated constantly lit or u nlit pixels may be present. 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 1280 x 800 has 1280 x 800 = 102400 0 pixels. Each pixel consists of
three subpixels (red, green and blue), so there are almost 3 million subpixels in total. According to ISO
9241-307 (class II), a m aximum of 2 light a n d 2 dark pixels and in addition 5 light or 10 dark subpixels
or an equivalent mix (1 light subpixel counts as 2 d ark subpixels) are allowed to be defective.
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 m ore defective pixels or
subpixels in a 5 x 5 pixel b lock.
Background li
ghting
LCD screens ar
e operated with background lighting. The luminosity o f the background
lighting can
decrease during the period of use of the notebook. However, you can
set the brigh
tness of your monitor individually.
