Touchscreen
Tou chs cr ee nNotes
High-quality TFT displays are installed in Tablet PCs from Fujitsu Technology Solutions Gm bH. 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 monitor. A
monitor resolution which differs from the specification can r esult in an unclear picture.
The screen resolution of your Tablet PC’s touchscree n is optimally set at the factory.
The standard of p roduction techniques today cannot guarantee a n absolutely fault-free screen
display. A few isolated constant lit or unlit pixels (picture e lements) 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 8 00 has 1 280 x 80 0 = 1024000 pixels. E ach pixel consists of
three subpixe ls (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 an d an additional 5 light or 10 dark
subpixels or a corresponding mix may be defecti ve (1 light subpixel counts as 2 dark subpixe ls).
Pixel
A pixel consists of 3 subpixels, normally red, green and
blue. A pixel is the smallest element that can be generated
by complete functionality of the display.
Subpixel
A su bpixel is a separately addressable internal structure
within a pixel that enhances the pixel function.
Cluster A cluster contain
s two or more defective pixels or
subpixels in a 5 x
5 pixel block.
Background l igh ting
TFT monitors are operated with backg round lighting. T he luminosity of the
background lighting can decrease wh ile the Tablet PC is in use. However, you
can set the brightness of your monitor individually.
Select display orientation (portrait or
landscape orientation)
Landscapeorientat ionPortraitorientationDisplayorientation
You can choose to use either portrait o r landscape orientation for the display.
The alignment of the screen always automa tically adapts to the a lignment in which you are using the
Tablet PC. If you hold the Tablet PC in portra it orientation, the image will be shown in portrait format.
If you hold the Tablet PC in landscape orientation, the image will be shown in landscape format.
If you want to disable automatic matching of the alignment, proceed as follows:
► From All apps, sele ct the option Settings.
► Ta p on Display and deactivate the Automatic screen rotation setting.

The tick on the setting disapp ears, matching of the alignment is disabled.
► To reactivate adaptation of the orientation, tap on the Automatic screen rotation setting again.

The tick on the setting appears, matching of the alignment is enab led.
