1) Non-Ignition Dot (Dark Defect) is defined as "A cell of which more than 50% area is not ignited"
2) Unstable Dot (Flickering) is defined as "A cell which repeats On and Off"
3) Uncontrollable Dot is defined as "A cell which is distinctly brighter or darker than other cells around it"
and/or "A cell of which color is distinctly different from that of other cells around it"
4) Non-Extinguishing Dot (brightness defect) is defined as "A cell of which more than 50% area is
always ON"
5) Stain is defined as "A blob due to local color contamination in white or simple color pattern"
