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.
The maximum permitted n umber of faulty pixels is stipulated in the international standard ISO
9241-307. In accordance with standard ISO 9241-3, LC D monitors by Fujitsu comply with Class II
for low resolutions an d Class I for resolutions of 1680 x 1050 (1764000 pixel) and higher.
Examples:
A flat-screen monitor with a resolution of 1280 x 1024 has 1280 x 1024 = 1310720 pixels. Each pixel
consists of three subpixels (red, green and blue), so there are almost 3.9 million subpixels in total.
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 co rrespon ding combination, may be faulty (1 lit subpixel counts as two unlit subpixels).
A flat-screen monitor with a resolution of 1920 x 1200 has 1920 x 1200 = 2304000 pixels. Each pixel
consists of three subpixels (red, green and blue), so there are almost 6.9 million subpixels in total.
According to ISO 9241-3 (Class I), a maximum of 2 lit and 2 unlit pixels plus 5 lit or 11 unlit subpixels,
or a co rrespon ding combination, may be faulty (1 lit subpixel counts as two unlit subpixels).
