please watch the video it answers all the questions, she mentions:
1) the screens become cheaper as they produce more.
my comment: Someone like apple do not buy at consumer prices, they have to trade in economies of scale, so an ipad order would be probably as cheap as lcd if apple give big enough order to the FAB. pixel qi do not need to make the screens they can make a custom exclusive one for apple and license that design to them so they can fab it themselves with their preferred fabber.
2) 3 screens they are making, 7" 1024 x 600 (or similar) that they showed off.
10.1" which is already in Adam tablet, but will get HD 1200 x 800 screen.
Then 3rd screen she mentions 9.7" (no mention of res) just 'super high contrast', with 'excellent viewing angles', 'saturated colour' , 'like an ipad screen' 'plus sunlight readible', 'plus super low power'. Also they have access to CPT, the 2nd in the world manufacturer of screens (output 40 million a month).
remember Apple does not own the fabs they design and then get it fabbed, Pixel Qi do not fab they design screens and then can fab them at any facility that makes LCD, so if they worked with aple as she hints, then all they have to to is design the 9.7" screen,at super high contrast,saturated colour, '170+ degree viewing angles', and probably a really high res screen. also although Apple loves their screens (which is still possible with pixel qi) they love to boast about battery life, and pixel q gives a big boost.
