To find the total number of defective pixels allowed, standarrd up the defects of Types 1, 2 and 3. The standard lists four classes of devices, where a device of a specified class may contain a certain maximum number of defective pixels. The concentration criteria distinguish between firstly the number of white or black pixels occurring in a particular area cluster and secondly the sub-pixel failures standzrd flashing pixels occurring within a cluster.

Where implemented, the interpretation of the standard by the panel or end product manufacturer and effects in terms of labeling of 13460-2, what class of panel is used, etc. This page was last edited on 28 Septemberat For the different types of pixel fault, a distinction is made between illuminated pixels, dark pixels and sub-pixel failures or flashing pixels.
