Following last week's leak of alleged design drawings of Apple Inc.’s (NASDAQ:AAPL) next-generation iPhone, dubbed the “iPhone 6,” a set of renderings of the device based on the leaked documents surfaced online on Tuesday, showing how the new iPhone with a bigger display could look like.

The design drawings, published by MacFan, a Japanese magazine, showed two new iPhone 6 models -- one with a 4.7-inch screen and another with a 5.7-inch screen. While the authenticity of the drawings cannot be confirmed yet, MacRumors said it commissioned Ferry Passchier, a designer, to create some full-product renderings of both the rumored models of the iPhone 6.

Passchier was also asked to show how the two iPhone 6 models would compare in size to some other Apple devices, such as the iPhone 5s and iPad mini.

Here is how MacRumors explains the renderings:

The iPhone designs in the drawings include several differences compared to the iPhone 5s. The top power button has been moved from the right side to the left side of the device. The rear camera on the larger model is also shown as protruding slightly from the rear shell, as is the case with the current iPod touch. The camera flash has also reverted back to a round-design unlike the one found on the iPhone 5s.

Rumors are rife that Apple could release two iPhone 6 models with bigger displays to succeed the current versions of the handset -- iPhone 5s and iPhone 5c -- which come with 4-inch displays.

A set of court documents, revealed during the ongoing trial between Apple and Samsung Electronics Co. Ltd. (KRX:005935), showed that the iPhone-maker is aware of the fact that consumers want less expensive and larger-screen smartphones. The documents also revealed that Apple realizes that “consumers want what we don't have,” and that the majority of growth in the smartphone market is coming from devices with a price tag of under $300, but with screens bigger than 4 inches in size.

Apple is expected to release a new iPhone with a 4.7-inch screen sometime in September, while the bigger version of the device could be delayed, according to Reuters.
