Back in late August, Reuters reported that Sharp had been experiencing low production yields on the iPhone 5 display, putting the company behind Apple's other two suppliers, Japan Display and LG Display.
MarketWatch now reports that Sharp has apparently ironed out its issues and has now begun shipping iPhone 5 displays into Apple's supply chain.
Mass production of the screens for the iPhone 5, which Apple unveiled Wednesday, began earlier this week at Sharp's factory in central Japan, the person said.
The start of Sharp's delivery of the screens could help ease concerns about whether Apple will have enough components to meet global demand for the new iPhone.
The iPhone 5 will launch in Apple's first round of markets on Friday, September 21, with pre-orders set to begin tomorrow.
