Reuters reports on comments from LG Display’s CEO regarding the company’s upcoming, thinner smartphone displays. According to Han Sang-beom, LG Display’s CEO, LG “just began mass production and [they] don’t expect any disruption in supplies.” Reuters seems to believe that the displays mentioned by LG are for the upcoming iPhone.

These particular displays are described as a thinner type of screen, likely built with in-cell technology. In-cell technology was previously rumored for the next-iPhone’s display, and the technology seemingly will allow Apple to build thinner iPhones.

Current and previous iPhone touch-screens include multiple display layers, including a separate LCD and touch sensor sheet. With in-cell technology, the two layers are combined, making the display thinner overall.

Photos of a purported next-generation iPhone LCD were recently posted online (shown above). We reported earlier this year that the next-generation iPhone would feature a taller, 4-inch (diagonal) display with a resolution of 640 x 1136. We corroborated those claims with iOS 6 based evidence earlier this month.

Notably, LG Display’s comments about new screens going into mass production come just about a month prior to Apple’s rumored September 12th event and September 21st iPhone launch.

The Wall Street Journal previously said that LG, Sharp, and a new company named Japan Display would be the supplier trio for Apple’s next-generation iPhone displays.
