With most of the major challenges tackled, this technology will surely bring the future of smartphone to next level - a smartphone with long battery life. The question is still coming down to the cost of the final product. Only time will tell.
The ability to create small geometry "reflective displays with vivid colors that can be viewed at nearly any angle" is an elegant development. In nature typically the colors vary with angle. An alternative approach would have been to use small colored spheres which would therefore maintain their color at all angles - but requires get good pigments and a larger scale.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
