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

His comments were embargoed until early Thursday morning.

Apple is planning a major product launch on September 12, stoking speculation that the world's most valuable technology company will announce the sale of its redesigned iPhone.

Apple is equipping the next iPhone with a larger screen after Samsung Electronics unveiled its latest Galaxy smartphone with a 4.8-inch touch-screen.

Sources have told Reuters that the panels for the new iPhone will be 4 inches corner to corner -- 30 percent bigger than current iPhones.

The iPhone screens will also be thinner than previous versions with the use of so-called in-cell panels. The new technology embeds touch sensors into the liquid crystal display, eliminating the touch-screen layer found in current iPhones.

Japan's Sharp Corp also said earlier this month it would start shipping screens destined for a new iPhone in August.
