We’ve heard several reports over the past few months that Apple is using a new, thinner display in its next iPhone. The tech is called in-cell, and will help slim down the handset.

Interestingly enough, LG Display’s CEO Han Sang-beom announced today that his company has just started mass-producing a new line of thinner, smartphone display panels…

Reuters reports on the CEO’s comments this evening, and it’s clear it believes that LG’s new display panels are going to be used in Apple’s next-generation iPhone.

“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.”

It’s worth noting that LG is a panel supplier for Apple, and the company was tapped as a next-gen iPhone display-maker by The Wall Street Journal back in May. So it’s possible that Reuters is spot-on, further confirming reports that the next iPhone will have a thinner, larger screen.

As far as the specs of the displays, they’re said to have a resolution of 1136 x 640 and a PPI (pixels per inch) of 326. Essentially they’ll have the same width and PPI as the iPhone 4S.

Apple is expected to unveil the new iPhone at a media event on September 12. Pre-orders are said to start the same day, with the handset arriving in retail stores the following week.
