A concept image of the Apple iPhone 6 shows a radical curved screen design.

Part of a string of concept images including a budget iPhone with a plastic case, MyVoucherCodes has commission the design showing what the iPhone 6 could look like. The design is based on a recent patent meaning a possible curved display. See also: iPhone 6 release date: When will Apple's next iPhone arrive?

The patent describes: "A consumer electronic product includes at least a transparent housing and a flexible display assembly enclosed within the transparent housing. In the described embodiment, the flexible display assembly is configured to present visual content at any portion of the transparent housing."

The patent also says the display can achieve "an illusion of depth perception" capable of "mimicking a 3D experience."

So the iPhone 6 could have a wraparound AMOLED display and the loss of the iconic physical home button. If so, it would be the biggest design overhaul of the iPhone since Apple launched the device in 2007.

However, Nickolay Lamm, the designer behind the concept, thinks it's unlikely that Apple will release an iPhone with this kind of design this year but it could feature in a future generation; perhaps the iPhone 7.

"Such a design may appear on the iPhone 6 or 7, or maybe never. It’s a cool design, but one which is unlikely to give Apple a sustainable competitive advantage. If Samsung sees that Apple’s curved iPhone is selling well, it can come out with a curved phone of its own. So, although this is a radical design change, Apple needs to look to new frontiers, new products, in order to be the “think different” Apple it was under Steve Jobs." said Lamm.
