Apple has suspended new iPad 2 panel orders from LG Display because of some serious production issues, say industry sources. LG's panels allegedly failed recent drop tests, during which backlight units malfunctioned. The company's yield rates, more critically, are said to be below Apple requirements. In July LG shipped somewhere between 2.5 and 2.6 million panels, a million units below its original goal for the month. The company's longer-term goal is 4 million a month.
