Which TV is right for me? (Device & Conquer)

The technology behind the screen that creates the image is the core of what you're paying for when you buy a TV.

Understanding the differences can be confusing and, frankly, very technical. Leave it to CNET's Brian Cooley to make it simple and narrow down your choice in just a few minutes. Luckily for even the least attentive consumer, there are very few bad TVs out there.

Toshiba and Bridgelux think they're worked out the key ingredient to making LED lighting mainstream: silicon.

As part of the deal, Toshiba has invested an undisclosed amount in Livermore, Calif.-based Bridgelux.

Liquid-cooled LED bulbs ready for summer

Switch Lighting's LED bulbs have similar technical specs to its competitors, but the startup is counting on clever design and good looks to stand out in a crowded field.

100,000 'firefly' LED bulbs float through Tokyo

For centuries, the people of Tokyo have been flocking to the Sumida River to see fireworks displays. This past weekend, though, they got a spectacle of a different sort as thousands of electric "fireflies" wafted downstream.

The Tokyo Hotaru Festival 2012 is a modern twist on the age-old Japanese love of watching fireflies along waterways. Some 100,000 blue LED light bulbs floated down the Sumida in imitation of the insects, long celebrated in haiku and other verse.

Measuring just over 3 inches across, the LED bulbs were charged with solar-generated electricity and later reclaimed in nets downstream. … Read more

Flashing LED guitar neck channels your inner rock star

I'm looking at my guitar sitting on a stand in the corner of the room. It just looks so plain. If only it had screaming LED lights blazing along the neck and lighting up as I shred my way through a folksy murder ballad.

My imaginary light show could soon become reality with NeckFX, a Kickstarter project that aims to turn regular guitar necks into finger-triggered light shows.… Read more

Why do plasma TVs look washed out in the store?

CNET Reader Rob asks:

I've been reading your articles on HDTV and find them very informative so, here's something I need cleared up. You mentioned how plasma TVs can control the brightness of individual pixels, made me think they should have a superior picture to LCD -- so I went looking at plasmas. I noticed that they seem to have a "washed out" look, an overall dimmer picture than LCD. Everywhere I go this seems to be the case. What's up with that? Thanks.

A common question, and a huge issue with plasmas, but not how you might think.… Read more
