a. Test program will allow maximum of one minor couplet in inner zone of pixel array.
b. No major couplet allowed.
Couplet definition
A failing pixel at X with a failing pixel at position [0] or [1] or [2] or [3] or [4] or [5] or [6] or [7] such that
there is a maximum of 2 failing pixels from the group of 9 pixels illustrated in
as a couplet fail. The example shown on the right in
location and at position [7].
The basic couplet definition is further subdivided into minor and major couplets. With respect to the
example in
extreme fail, that is a “stuck at black” or “stuck at white”, but the second pixel in the pair must differ
from the local pixel average by less than 15% of that average value. If the second pixel in the couplet
differs by more than 15% of the local pixel average value then this would be defined as a major
couplet.
Note that the test program considers a couplet as 2 independent pixels. If the test identifies two
independent pixel fails (pixels that differ by more than 15% from pixel average of neighbors) that
form a couplet with 2 minor pixel fails within the inner area, the device fails the test and is rejected.
If however the test identifies 2 couplets where the pixels span the border between the inner and
outer areas and where only one of the pixels in the inner area is determined as a major fail and the
other a minor fail, then this device passes the test.
Cluster definition
We define a cluster fail as a failing pixel with at least two adjacent failing pixels. In the example from
Figure 34
A sensor containing a cluster is always rejected.
Summary pass criteria
Test program will allow maximum of two minor couplets in outer zone of pixel array.
