LG announces a pair of Minibeam miniature battery-powered projectors-- the Ultra Short-Throw (UST) PH450U able to projecto 80-inch images and the "extremely portable" PH150G.
The PH450U projects an 80-inch 1280 x 720 resolution image from a distance of 33cm, making it ideal for rooms lacking in viewing space. Users can also set it upright on one end to render images on any flat, horizontal surfaces, turning tables or even floors into a movie screen. Image brightness reaches 450 lumens, contrast is 100000:1 and lamp life reaches up to 30000 hours.
Connectivity comes through HDMI (with MHL capability) or USB, and LG claims the battery powers 2.5 hours of projection on a single charge.
