Working with the Tablet PC

Touchscreen

High-quality TFT displays are installed in Tablet PCs from Fujitsu Technology Solutions GmbH. 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 result in an unclear picture.

The screen resolution of your Tablet PC’s touchscreen is optimally 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 may be defective (1 light subpixel counts as 2 dark subpixels).

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 subpixel is a separately addressable internal structure
	within a pixel that enhances the pixel function.
Cluster	A cluster contains two or more defective pixels or
	subpixels in a 5 x 5 pixel block.

Background lighting

TFT monitors are operated with background lighting. The luminosity of the background lighting can decrease while the Tablet PC is in use. However, you can set the brightness of your monitor individually.

Select display orientation (portrait or landscape orientation)

You can choose to use either portrait or landscape orientation for the display.

The alignment of the screen always automatically adapts to the alignment in which you are using the Tablet PC. If you hold the Tablet PC in portrait 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, select the option Settings.

►Tap on Display and activate the setting Auto-rotate screen.

The tick on the setting disappears, matching of the alignment is disabled.

►To re-enable matching of the alignment, tap again on the setting Auto-rotate screen.

The tick on the setting appears, matching of the alignment is enabled.
