It's simple how it works. They have an LCD over a mirror substrate. If no current is going to the pixel of the LCD, a mirror is shown. If there is current, then it's black. They shine a laser at it, and it's reflected off the mirror (or not) and thus projects the image onto whatever surface you want. Since they are using lasers, and refraction, no focusing is needed. Also, the lasers don't use much voltage, and are very bright even in regularly lit rooms. You should check out 'light blue optics' webpage for more information.
