New display technology

Light Blue Optics has developed a hologram-based technology for miniature laser projectors. Their latest demonstrator unit is matchbox-sized.

Projectors based on this technology could be used to display images from a range of mobile devices, the most obvious being PDAs and mobile phones.

If you want to know more about the technology, type 'light blue optics hologram' into Google. The significance of this development is that it overcomes the size limitation of conventional projection techniques and, for that matter, LCD screens. It has no prisms, no fans, in fact, no moving parts at all. Its power consumption is modest and the image it produces is high-resolution and always in focus.

The technology works, and it could be mass-produced very cheaply. Imagine a mobile phone where you could project a high-resolution image on to any available flat surface. It could be happening sooner than you think.
