Dark Dot Defects

Black dot defects appear as pixels or sub-pixels that are always dark or "off". These are the examples of black dot defects:

	Two adjacent dark dots=	Two	dark	dots, specifications
One dark dot		defines	the	minimum distance
	1 pair of dark dots
		between dark dots

Proximity of Pixel Defects

Because pixel and sub-pixels defects of the same type that are nearby one another may be more noticeable, Philips also specifies tolerances for the proximity of pixel defects. In the table below you can find specifications about:

∙Allowed amount of adjacent dark dots = (adjacent dark dots =1 pair of dark dots)

∙Minimum distance between dark dots

∙Total no. of all defective dots
