Bright or dark pixels
It is not possible to guarantee an absolutely fault-free screen monitor with curre nt
production technology. A few isolated permanently bright or dark pixels (picture
elements) may be present. The maximum permitted number of such faulty pixels is
specified in the international standard ISO 9241-3 (Class II).
Examples:
A 43/48 m (17"/19“) flat-screen monitor with a resolution of 1280 x 1024 has 1280 x 1024 =
1310720 pixels. Each p ixel 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
bright an d 3 dark pixels plus an additional 6 bright or 13 dark subpixels or an equivalent mix
(1 bright subpixel counts as 2 dark subpixels) are allowed to be defective .
Pixel
A pixel consists of 3 subpixels, normally red, green and blue. A pixel is
the smallest element that can be g enerat ed by the overall functionality of
the monitor.
Subpixel
A subpixel is a separately addressable intern a l structu re w ithin a pixel that
extends the functionality of the pixel.
