Working with the notebook
LCD screen
LCDscreenNotes
Fujitsu notebooks have high-quality LCD monitors (TFT). For technical reasons, these
monitors are manufactured for a specific resolution. An optim al, clear picture c an only
be e nsu red with the resolutio n intended for the relevant monitor. A resolution which
differs from the specification can result in an unclear picture.
The resolution of your note book’s monitor is optimally set at th e factory.
Current production techno logy cannot guarantee an a bsolutely fault-free screen display. A few
isolated constantly lit or unlit pixels may be present. The maximum permitted number of such
faulty pixels is specified in the international standard ISO 9241-307 (class II).
Example:
A screen with an HD resolution of 1366 x 768 has 1366 x 768 = 1049088 pixels. E ach pixel consists of
three subpixels (red, green and blue), so th ere are almost 3 million subpixels in total. According to ISO
9241-307 (class II), a ma ximum of 2 light and 2 dark pixels and in addition 5 light or 10 dark subpixels
or an equivalent mix (1 light subpixel counts as 2 dark 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 subpixel is a sep
arately addre ssable internal structure
within a pixel tha
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
LCD monitors a
re operated with background lighting. The luminosity of the background
lighting can
decrease during the period of use of the note book. However, you can
set the brigh
tness of you r monitor individually.

Ambient Light Sensor
In the case of delivery with a Windows operating system, the screen brightness is regulated
by means of the amb ient light sen sor and depending on the p a rticu lar light co nditions. This
results i n optimum readability and longer battery life at the same time.
