LCD displays are made up of a set number of pixels and each pixel is made from 3 sub-pixels -one Red, one Blue and one Green. Every sub-pixel is addressed by its own transistor and so the manufacture of a glass substrate is very complex.
Hannspad tablets are covered by a 0/4/4 pixel policy: 0 bright dots / 4 dark dots / 4 total defect dots.
Only products above this tolerance will be considered as defective and thus will be treated in Warranty.
