The PicoPix looks like a miniature version of a standard projector and is designed to be carried everywhere. It uses an LED lamp and liquid crystal on silicon (LCoS) technology to project a 52in diagonal image at 7ft. It can run on batteries for two and a half hours, and play MP4 videos from USB drives.
LCoS is much like digital light processing (DLP) technology, but where DLP uses an array of moving micro-mirrors to reflect a light source either through the lens or away from it, depending on whether the pixel is on or off, LCoS uses liquid crystals on top of a reflective surface. These block light or allow it to reach the reflective surface below – if light is allowed to hit the mirror, it’s reflected out through the lens. In DLP projectors, the light then passes through red, green and blue filters in a spinning colour wheel to produce three colour images, one after another. The fast speed of the wheel tricks your eyes into seeing a full-colour image. Read the rest of this entry »
