A defect found in some iPhone 5 display panels may result in short supply next month, suggesting that Apple’s iPhone launch may once again be marred by angry customers unable to get their hands on Apple’s latest and greatest.

The defect described involves a bubble that appears between the panel and the lamination layer only after the displays are sent out for assembly. Wintek would not confirm or deny the report when contacted by DigiTimes for comment, though it did state that all of its products are being delivered on schedule. According to the report, Apple’s fourth-quarter shipment goal for the iPhone 5 is in the 25-26 million unit range. Wintek is estimated to be supplying between 20% and 25% of the display panels used in Apple’s iPhone 5.
