When the iPhone 5’s opening-weekend sales only reached 5 million units instead of the sky-high estimates some Wall Street analysts’ offered ahead of launch, investors panicked and Apple’s (AAPL) stock took a hit. Some might say the record-setting sales figure is still “epic,” but Apple bulls whose projections overshot actual sales were quick to blame the disparity on supply shortages. Sharp’s display panel production in particular was said to be falling short, but an unnamed company executive on Friday confirmed that it is now producing “adequate volumes” of display panels Reuters says are destined for Apple’s new iPhone. The iPhone 5 launched on several regional U.S. carriers and in 22 new countries earlier on Friday.
