Samsung did not detail whether the smartphone will go on sale anytime soon or how much it will cost. Samsung only showed off the display of the smartphone and didn't give a clear look at the body of the smartphone. 

Having said that, the smartphone looks like a normal smartphone when folded and opens up like a book to transform into a 7.3-inch display. It will be the largest smartphone screen ever released and is big enough to run three apps side by side. According to Samsung, the screen can be folded thousands of time and the company is also looking into a screen that rolls and stretches. 

When folded, the display will be 4.85-inches in size and have an aspect ratio of 21:9 and resolution of 840x1,960 pixels. As a tablet, the 7.3-inch Main Display will have a 4.2:3 aspect ratio with 1,536x2,152 pixel resolution. When unfolded the Cover Display automatically turns off.
