LCD screen

Notes LCDscreen
Fujitsu notebooks have high-quality LCD monitors (TFT). For technical reasons, these
monitors are manufactured for a specific resolution. An optimal, clear picture can only
be ensured with the resolution intended for the relevant monitor. A resolution which
differs from the specification can result in an unclear picture.
The resolution of your notebook's monitor is optimally set at the factory.
Current production technology cannot guarantee an absolutely 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. 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 maximum 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.

Background lighting
LCD monitors are operated with background lighting. The luminosity of the background
lighting can decrease during the period of use of the notebook. However, you can
set the brightness of your monitor individually.

Ambient Light Sensor

In the case of delivery with a Windows operating system, the screen brightness is regulated
by means of the ambient light sensor and depending on the particular light conditions. This
results in optimum readability and longer battery life at the same time.

Using a device as a tablet PC

You can execute commands as follows:
• using the pen (supplied with your device).
• using your fingers
Fujitsu
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.
A subpixel is a separately addressable internal structure
within a pixel that enhances the pixel function.
A cluster contains two or more defective pixels or
subpixels in a 5 x 5 pixel block.
