Wirelessly-powered TVs are nice, and transparent displays are cool and all, but what about an ambient light-powered transparent LCD? Well, that's nothing short of awesome. Samsung showed off just such a device at CeBIT 2011 last week -- a prototype 46-inch display with 1920 x 1080 resolution and ten-finger touchscreen capability. We aren't sure what kind of black magic Sammy put in this thing, but it's an incredible feat of engineering to make such a large display -- and its accompanying solar cells -- efficient enough to run exclusively off the juice it pulls from surrounding light sources. No word on how the photon-powered LCD compares to existing HD monitors in terms of brightness, refresh rates, or color reproduction, but a muted picture is a small price to pay for cutting the electrical cord forever.

Update: It appears that the source article misunderstood the way this LCD is powered -- there are no solar panels involved here; the ambient light is merely to replace the traditional backlight rather than powering the device.
