Using your notebook
Permanently unlit or lit pixels
The standard of production techniques today cannot guarantee an absolutely fault-free screen
display. A few isolated constant lit or unlit pixels may be present. The maximum permitted number
of pixels faults is stipulated in the strict international standard ISO 13406-2 (Class II).
Example:
A 15" LCD screen monitor with a resolution of 1024 x 768 has 1024 x 768 = 786432 pixels. Each
pixel consists of three subpixels (red, green and blue), so there are almost 2.4 million subpixels in
total. According to ISO 13406-2 (Class II), a maximum of 4 pixels and 5 subpixels may be defective,
i.e. a total of 17 defective subpixels. That is approx. 0.0007 % of the entire set of 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 during the period of use of the notebook. However, you can
set the brightness of your monitor individually.
