There are very few panel manufacturers these days, and many panels use the same or can be made to use the same outputs/inputs. To that end it could well be they wanted so many screens of a given size, resolution, attachment method, input and so forth and gone and tapped a bunch of sources to make it happen. If their approach to dead pixels is what it is then that might also speak to them doing things somewhat on the cheap.how is it cost effective to produce the 2 types of screens?
