How "new" is the new Apple iPad, exactly? iFixit dismantled it and confirmed the obvious23
iFixit even took the liberty of swapping in the digitizer and LCD from the original iPad Air. The digitizer worked, while the LCD has backlight problems. However, the Air 1 can take the new iPad's LCD, and the same display timing controller is found in both tablets. The LCD unit on the new iPad is different – it's not the old LG panel, but a new and unmarked one. iFixit also observed that the unfused display design with no lamination and coating makes for a brighter display than the iPad Air 2's, and its tests confirmed the panel is 44% brighter than the iPad Air's. The tablets have an identical battery pack as well.
While the revelation might seem anti-climactic, it's just how business works. Apple won't profit by building budget models from the ground up. That's why it dusts off old tech that's grown cheap to manufacture and is still good for effective use, then markets it in its typical fashion. This is Tim Cook's Apple for you – all calculated, big margin, low risk, cautiously innovative products. Sometimes outright lazy products like the new iPad and the iPhone SE. Thankfully, they are still great for what they are, just like Apple's big hitters.
