FLM-19XX: Model Numbers FLM-1911, FLM-1911M, FLA-1911B 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.

A ZONE: The center rectangle, with height of ½ of total height and width of ½ of total width A ZONE: Item Specification Bright cell 0 Dark cell 1 or less All bright and dark cells combined 1 or less B ZONE: Item Specification Bright cell 3 or less Dark cell 5 or less All bright and dark cells combined 5 or less
