Several rumors have claimed that the upcoming iPhone 6 would be even thinner than the iPhone 5s. A report from LEDinside suggests that the extra margin to reduce thickness would come from newer LED backlights that are thinner and lighter.
According to sources from Apple supply chain, the iPhone 6 is likely to be released in June 2014, and will have larger monitor size of 4.7”. Industry insiders also projected the iPhone 6 will have a much lighter frame, which will lead to upgrades in LED backlight specs. In the previous generation, the iPhone used 0.6[mm] side-view type LED, in contrast the new iPhone will probably be adopting 0.4[mm] side-view type LED.
The iPhone 5s is 7.6mm thick, and the iPhone 6 is rumored to have an ultra-thin form factor as thin as 6mm.
While Apple has generally released new iPhones in September, this isn’t the first report this year to claim that the iPhone 6 will be launched in June. A report from earlier this month claimed that the iPhone would be released at WWDC, and would run iOS 7.2 rather than iOS 8. It’s also worth noting, that almost all iPhone 6 rumors note the existence of two models, one with a 4.7 inch, and the other with a display larger than 5.5-inches.
