Sharp says iPhone 5 displays being made for Apple in 'adequate volumes'

The unnamed Sharp official made the comments at a press briefing in Osaka, Japan, and spoke on condition he would not be identified, according to Reuters. The comments suggest that any earlier issues the company was rumored to have experienced have since passed.

Sharp was previously said to have fallen behind schedule in producing the new in-cell touch panel displays for Apple's iPhone 5. Those screens are reportedly being mass produced at the company's Kameyama plant in central Japan.

Specifically, the new in-cell panels were said to have low production yields at the Sharp plant. An unnamed source who spoke with Reuters speculated that Apple could "sweeten financial incentives to secure an acceleration of production."

In addition to Sharp, iPhone 5 displays are also being supplied to Apple by LG Display and the newly formed Japan Display Inc., a venture from the LCD operations of Sony and Hitachi.

The new iPhone features a taller 4-inch screen that allows for another row of applications on the device's home screen. The new in-cell touch technology allows the component to be thinner, aiding in the iPhone 5 being both 18 percent thinner and 20 percent lighter than its predecessor.
