Name: Kairen Projector X Pro920
Category: portable projector
Price: JPY36,540
Release date in Japan: Early August, 2008
Saitama-based Kairen YK is about to release the smallest projector I've ever heard of. It's a mere 9 x 8 x 4.4 cm and weighs a scant 190 grams. Yet it's a real projector, designed for use with your iPod, DVD player, or other media player.
Input is via a mini AV jack for DVD players, or D-Sub15 pin connector for PCs. The sold-separately "VGA SMART" kit allows connection to smart phones, letting a phone with slideshow or PDF display capabilities run a full presentation for a (small) table of people.
At 10 lumens, the Pro920's LED light won't outshine the big models. In fact, it sounds downright dim. Kairen says the brightness is good for a 25-inch screen (presumably in a dark room), but you'd do well to confirm visibility yourself with a store display model before dropping the cash.
Maximum input resolution is 1024x768; output is via a VGA (640x480) 0.44-inch LCoS panel with 4:3 aspect ratio. Completing the low-rent theater experience is a 1W monaural speaker and manual focus.
