Looking through your comment history it seems that you have interrogated any poster who was ever mentioned patent problems, and demanded that they provide you with sources. It is not clear why they are required to do that.
That is quite a jumble of overlapping / inter-locking patents. The goal is to prevent competition using similar technology. It looks effective. And to answer your next question, no I'm not in the display industry, just thought it seemed interesting.
