Notes: A bright spot is a subpixel which, when a black screen is being displayed, is visible through a 20%
transmission ND filter to an unaided eye at least 45 cm [18”] away from the display surface in a dark room.
Dark spots in which the dark spot area divided by the subpixel area is less than 1/3 are not counted.
