Permanently unlit or lit pixels
Today’s production techniques cannot guaran tee an absolutely fault-free screen display. Depending
on the total number of pixels (resolution), there may be a few constantly lit or unlit pixe ls or subpixels.

Pixel
A pixel consists of 3 subpixels, normally red, green and blue. A pixel is
the smallest element that can b e generated by complete fun ctionality of
the display.
Subpixel
A subpixel is a separately addressable intern al structure within a pixel that
enhances the pixel function.
Pixel fault All 3 subpixels are lit/unlit. The result is a b righter or da rker pixel.
Subpixel fault Only one subpixel is lit/unlit. T he result is a pixel with missing colours.
The maximum permitted number of f aulty pixels is stipulated in t he international stan dard
ISO 9241-307. The LCD displays from F ujitsu comply to at least Class I. Fujitsu guarantees
displays that are free of pixel faults, so that only subp ixel faults may occur.
Example
Examples: A flat-screen d isp lay w ith a resolution of 1280 x 1024 has 1280 x 1024 = 1310720 pixels.
Each pixel consists of thre e subpixels (red, green and blue), making a total of about 3,9 million
subpixels. According to ISO 9241-3 (Class II), a maximum of 3 lit and 3 unlit pixels plus 7 lit or 13 unlit
subpixels, or a correspond ing combination, may be faulty (1 lit subpixel counts as two unlit subp ixels).
A flat-screen display with a resolution of 1920 x 1080 has 1920 x 1080 = 2073600 pixels. Each
pixel consists of three subpixels (red, green and blue), making a total of about 6,2 million subpixels.
According to ISO 9241-3 (Class I), a maximum of 2 lit and 2 unlit pixels plus 5 lit or 10 unlit subpixels,
or a corresponding combination, may be faulty (1 lit subpixel counts as two unlit subpixels). Because
Fujitsu supplies displays that are free of pixel faults, only subpixel faults enter into the evaluation.
