A new breakdown of tablet display shipments by Displaybank on Friday has hinted that iPad shipments could be much higher than they were in the winter. Deliveries of 9.7-inch touchscreens, used almost exclusively by the iPad, hit 5.38 million units in May alone. About 4.5 million of those were from Apple's two main contractors for iPad screens, LG Display (three million) and Samsung (1.5 million).
