Anything’s a screen for the Pico Projector
Texas Instruments’s Pico Projector is small enough to fit in a cellphone (albeit a chunky one, if the prototype we saw is any indication) but bright enough to shine a 15-inch-wide image even in a well-lit room. TI first showed the device at last year’s Consumer Electronics Show (CES), and it’s made only one public appearance since then, said TI representatives who busted it out during a small reception in New York last night.
Seeing really is believing with this tech. Point the Pico at any even vaguely flat surface—a wall, someone’s back, the palm of your hand—and it’s movie time. The model I tried works by shining red, green, and blue lasers on a tiny digital micromirror device—the same kind of chip that powers DLP movie-theater and living room projectors and rear-projection TVs. A new version in development uses light emitting diodes to save money, power and heat. Good thing, too, because the Pico I held last year made a loud whirring sound, courtesy of the cooling fan.
So when can you have your own Pico? It will likely first appear in a cellphone, and probably next year, said TI representative Kateri Gemperle. Will the first cellphone maker break the news at CES in early January? “We don’t think a manufacturer would let CES go by without announcing something,” said Gemperle. —Sean Captain
Rear-projection TVs are big, beautiful and bewildering. Which kind is right for you?

When buying a big-screen TV, you can go flat or you can go fat. Flat (with a plasma or direct-view LCD screen) means you can hang your TV on the wall, but you'll feel the pinch in the checkout lane. In the fat camp are the rear-projection screens, which offer larger screen sizes, great resolution and more affordable prices. Rear-projection TVs will also be the first to be
digital-cable-ready, eliminating the need for a digital-cable box. And the best news of all-they're not even that fat anymore.
With many technologies to choose from, it can get complicated. Here's how to translate the specs.

Enter a showroom this fall and you'll find the widest selection of big-screen HDTVs ever, each incorporating different tech. There are hang-on-the-wall plasma and LCD sets, along with DLP (digital light processing), LCD, and LCoS (liquid crystal on silicon) rear-projection TVs. Follow these guidelines: Look for a brightness rating of at least 400 candelas per meter squared (expressed as cd/m2), which is double the brightness of a typical direct-view set. Insist on a contrast ratio (the visual difference between the blackest black and the whitest white) of 400:1.
