Operators are standing by…
Of course Apple is not a primary manufacturer of LCD panels; like everyone else, they buy their panels from someone like LG. Due to how much Apple loves IPS technology, which I cannot blame them for, they in fact do purchase their displays from LG.
If you have an itchy soldering iron, so can you.
According to EmertHacks, the LG part number for retina iPad screens is LP097QX1-SPA1. The blog post states that he could find the panel for as cheap as $55, but my own digging game up with costs between $60 and $200 plus shipping. These panels are mostly destined to iPad repair shops, but you can give it a better home.
With under $20 of other parts, this panel could be attached to a DisplayPort connection. All said and done, you could have a 2048×1536 9.7" display with an 800:1 static contrast ratio for about $70.
