LG launches production of 4in display, possibly for use in iPhone 5

LG Display, one of the world’s leading flat-panel screen manufacturers, has kicked off the mass production of a new, thinner display expected to be used in Apple’s sixth-generation iPhone, Reuters has reported.

"We just began mass production and we don't expect any disruption in supplies," LG Display chief executive Han Sang-beom told reporters late on Wednesday.

LG and Samsung, the consumer electronics giant currently embroiled in a legal battle with Apple over alleged patent infringement, are the Cupertino-based company’s primary display suppliers, making components used for the iPhone, iPad, and iPod touch screens.

Previous reports have suggested that Sharp and Toshiba could be involved in producing the displays for the so-called iPhone 5, though that does not stop Apple from procuring the screens from multiple sources.

In July, it was reported that Apple would begin incorporating in-cell technology in its displays - a technique that would allow it to offer slimmer capacitive touch screens without compromising their functionality. In-cell displays incorporate touch capability into the LCD manufacturing process, ultimately eliminating the need for a third touch layer and radically reducing a device’s thickness.

The iPhone 5 is also expected to boast a 4in display, 30 per cent bigger than the current model’s 3.5in screen. Apple is expected to introduce these changes to make its next-generation smartphone more competitive and more in-line with market trends, as it strives to wrest away market share from the likes of smartphone behemoth Samsung, whose flagship Galaxy S3 handset features a 4.8in screen.

The new iPhone is expected to be announced at a product launch next month, and the rumours will likely continue to trickle in until then.
