Samsung provides several examples of how back touch could be useful on a transparent device, including the ability to open applications or control a video without obscuring the display. Other examples include moving objects that sit on the bottom layer of a multi-layered screen, and strengthening unlock screen with dual-sided passwords. Samsung is no stranger to transparent displays so it wouldn t be too surprising to see the company try rolling out a smartphone with a curved see-through screen at some point over the next few years.
