There haven’t been many attempts at a phone with an inbuilt projector, in fact, we can’t think of one. There was the LG eXpo on AT&T, a Windows Mobile phone from 2009, that allowed you to buy a (rather expensive) projector add-on. The eXpo saw limited appeal, and the technology just wasn’t there yet.
Samsung is hoping that the world is ready for a projector-phone with their announcement of the Galaxy Beam. It’s an Android 2.3 Gingerbread device with a 4″ WVGA display, a 1GHz dual-core CPU, a 5MP camera, and a 2,000mAh battery. The most important aspect of the phone, of course, is the projector, which provides 15 lumens of brightness.
It’s a bit thick at nearly 13mm in depth, but in exchange for the extra bulk, you get the unheard of ability to project what you’re seeing on your phone’s display to a nearby wall or screen. Pretty neat!
