The first prototype of a device with a double-sided and transparent display was demo'd recently in Japan. The project is a joint effort between NTT DoCoMo and Fujitsu. While the prototype shown packs a 2.4-inch display with a resolution of 240x320 pixels the creators realize the resolution is to low to end up in retail devices and they acknowledge this in the video. The project continues to evolve, but the future looks very promising for some mind blowing apps and smartphones sporting this tech. Check out the video and share your thoughts.
