Apple is asking suppliers to manufacture 70 to 80 million 4.7-inch and 5.5-inch iPhone 6 units by the year’s end, reports the WSJ.
Its forecast for what is commonly called the iPhone 6 is significantly larger than the initial order last year of between 50 million and 60 million versions of the iPhone 5S and 5C—which had a display measuring 4-inches diagonally, these people said. Both of the coming models are expected to feature metal cases similar to the iPhone 5S and likely come in multiple colors, these people said.
The Journal says that one concern is the production of the 5.5-inch display. Manufacturing is complicated because the display reportedly uses in-cell technology, allowing the screens to be thinner and lighter by integrating touch sensors into the LCD and making a separate touch screen layer.
To account for the possibility of poor yield on the larger displays, Apple has component suppliers to prepare for up to 120 million iPhones by year’s end. It did the same last year, asking suppliers to prepare for 90 million iPhones.
