ISO 13406-2 Class II standard (none / 0) (#6)
by Anonymous User on Tue Mar 07, 2006 at 12:03:13 PM PDT

The ISO standard says "A flat panel display should not have pixel faults" (http://www.viewsoniceurope.com/data/63/I13406e2.pdf)

My interpretation of the full text is that if there are dead pixels then it is faulty.

"Also pixel faults are being identified. A flat panel display should not have pixel faults, i.e. fault class I. According to ISO 13406-2 further fault classes with the following number of faults are specified. Types 1, 2 or 3 differentiate pixels, which always illuminated, never illuminated or e.g. contain subpixel faults:"

Fault Class Type 1 Type 2 Type 3
----------- ------ ------ ------
I             0       0     0
II            2       2     5
III           5      15    50
IV           50     150   500
