The
EN ISO 9241-307
standard defi nes, amongst other things, the generally applicable
guidelines relating to pixel defects. Pixel defects are categorised into four fault classes
and three defect types. Every individual pixel consists of three sub-pixels, each of
which is assigned a basic colour (red, green, blue).

Pixel defect types:
• Type
1:
permanently illuminated pixel (bright, white dot) even when not activated. A
white pixel occurs due to the illumination of all three sub-pixels.
• Type
2:
non-illuminated pixel (dark, black dot) even when activated.
• Type
3:
abnormal or faulty red, green or blue sub-pixel (e.g. permanently illuminated at
half brightness, one colour not illuminated, fl ashing or fl ickering but not type 1
or 2)
Supplement: Type 3 cluster (= failure of two or more sub-pixels within a 5 x 5 pixel
block). A cluster is a fi eld of 5 x 5 pixels (15 x 5 sub-pixels).
