In-cell tech slows iPhone 5 production

If you are still waiting for your iPhone 5, you can apparently blame the phone's new display for the slowdown.

Apple's decision to use a thinner, lighter touch screen has contributed to the iPhone 5 backlog, which currently stands at three to four weeks, according to Bloomberg.

Apple's in-cell screen technology combines the display and touch sensors into a single component, making the handset more slender. Though the new feature may have played a role in the firm selling 5 million smartphone in three days, it is also more difficult to produce than earlier iPhone screens, which has slowed production.

IHS iSuppli senior principal analyst Tom Dinges likened the iPhone 5 launch to the opening weekend of a summer blockbuster film. "They needed to get a lot of products in the door during a tight window, and these supply constraints that were talked about probably did have some impact," he told Bloomberg.

The displays are made by LG Display and Japan Display, though Apple has also enlisted the help of Sharp to reduce reliance on the other companies, Bloomberg reported. But the supply-and-demand issue may be short-lived, since big-spender Apple will likely be first in line for new parts.

Apple CEO Tim Cook said recently that the company is "working hard to get an iPhone 5 into the hands of every customer who wants one as quickly as possible." Despite initial sell-outs, stores continue to receive shipments regularly, he said.
