Tablet screen shipments spiked 35.5 percent in September in the wake of a seven-inch tablet boom, researchers at WitsView said in a new study. About 9.57 million of their panels shipped just in September, 1.82 million of which were for the smaller devices. The Amazon Kindle Fire, ASUS Eee Pad MeMo, the HTC Flyer, and possibly a new Nook Color were all adding to the tally.
