Display Cell Defect Specification - Polaroid FLM-2632 Service Manual

In some cases, a panel may have defective cells that cannot be controlled.
These defective cells can be categorized into two types;
(1) Non-lighting or dark cell defect: defect in which the cell is always off
(2) Non-extinguishing or bright cell defect: defect in which the cell is always on
The display cell defect specifications define the allowed limits for display cell defects and are
used as the criteria in determining whether a panel is replaced.
