Marcel Sieler, the scientist behind the project, claims that if the new system were scaled up to the size of current pico projectors, it would produce about 90 lumens--pretty impressive. As it stands, the projector is tiny enough to fit inside a smart phone, but the problem is that even existing pico projectors are really not that bright--you need to use them in a dark room for it to be worth your while, and even then clearest images are rather small and dim. Sieler is currently working to reduce the LCD pixels from 8.5 microns to 3. But if it's going to be worth it to incorporate pico projectors into smaller gadgets like smartphones, we'll need a combination of miniature size and very bright images (with higher resolutions). For now, still, it looks like a choice between one and the other.
