2.3.4 Inspection Criteria
Definition of dot defect:
If the size of a dot defect is larger than 0.5 times a single pixel, it can be regarded as one dot
defect
Bright dot: Dot appears bright and the size is fixed in a black pattern.
Dark dot: Dot appears dark and the size is fixed in pure red, green and blue pattern.
2.3.4.1 Display defects
The size of a circular area is defined by the average of the size along the horizontal axis (=a)
and the vertical axis (=b), i.e. D=(a+b)/2. The size of a lint/scratch is defined by its with (=W)
and its length (=L).
