LCDscreenNotes
High-quality LCD screens (TFT) are installed in Fujitsu notebooks. For technical reasons,
these screens are m an ufactured for a particular resolution. An optimum and sharp image can
only be ensured with the resolution intende d for the particular screen. A screen resolution
which differs from the sp e cication can result in an unclear image.
The resolution of your notebook’s screen is set to the optimum at the factory.
With the present standards of production technology, absolutely awless screen images
cannot be guaranteed. There may be a few constantly light or dark pixels (picture
elements) on the screen. The maximum permitted numb er of such faulty pixels is
specied in the international standard ISO 9241-307 (Class II).
Example:
A monitor with HD resolution 1366 x 768 ha s 1366 x 768 = 1049088 pixels. Each pixel consists of
three subpixels (red, green and b lue), making a total of about 3 million subpixels. According t o ISO
9241-307 (class II), a maximum of 2 light a nd 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, no rmally red, green and
blue. A pixel is the
smallest element that can be generated
by complete functi
onality of the display.
Subpixel
A subpixel is a sep
arately add ressable internal structure
within a pixel tha
t enhances the pixel function.
Cluster A cluster contains two or more defective p ixels or
subpixels in a 5 x 5 pixel block.
