The next-generation iPhone will feature a thinner display that incorporates in-cell technology, according to a report in The Wall Street Journal.
In-cell technology would mean the iPhone's touch sensors and LCD are combined into a single layer, doing away with the need to have a separate touch-screen layer.
As well as enabling thinner screens, in-cell panels are also thought to be cheaper to produce than the current two-layer set-up.
LCD screen makers Sharp, LG Display, and Japan Display are mass-producing the in-cell panels for the screen, according to the Journal. Apple's use of in-cell technology is seen as part of its efforts to take on Samsung's own push on OLED technology. OLED is found in Samsung's current flagship device, the Galaxy S III, which boasts a 4.8-inch screen and a design that shaves a few millimeters off the iPhone's thickness.
The thinner screen could come as part of a move by Apple to increase the screen size of the next iPhone; the Journal reported in May that the forthcoming device will sport a 4-inch display.
Previous generations of the iPhone, despite several design changes, have retained a 3.5-inch screen since the device's debut in 2007.
The next-generation iPhone is expected to launch in or around October, in time for the holiday-shopping season.
