It's amazing how many functions can be crammed into one tiny handheld device, but then it's a shame how little you can do with such a small display. The HTC Flex smartphone tackles this problem by providing you with a built-in slide-out screen that adds no extra bulk to the super slim gadget.
Not simply suggesting the addition of an expandable visual display, this concept by Kareem Pownall integrates touchscreen technology as the means to interact with the transparent membrane. For watching movies, looking at photos and carrying on video calls, this futuristic feature greatly enhances the capabilities and one's expectations of a cellphone. And as if that wasn't enough, the HTC Flex smartphone is already equipped with two fixed elongated screens.
