Defects
Blemish Description
Hot/Dead Pixel defects Typical 0.0025%
Max 0.005%
Any pixel that deviates by ±20% from the average of
neighboring pixels at 50% saturation including pixel stuck at 0
and maximum saturated value.
Spot defects none Grouping of more than 8 pixel defects within a sub-area of 3x3
pixels, to a maximum spot size of 7x7 pixels.
Clusters defects none Grouping of more than 5 single pixel defects in a 3x3 kernel.
Column defects none Vertical grouping of more than 10 contiguous pixel defects
along a single column.
Row defects none Horizontal grouping of more than 10 contiguous pixel defects
along a single row.
