When you go shopping for a flat-panel television these days, the vast majority of available models are LCD TVs. Today's LCDs are super-slim, super-bright, and super-colorful thanks to many improvements made since Sharp introduced the first commercial LCD TV—with a screen measuring a whopping 14 inches—in 1988.

But exactly how does an LCD TV work?

Sony 46HX929 46″ Backlit LED-Array HDTV

Chris Heinonen

All LED LCD TVs are not designed the same. Manufacturers have two approaches they can take with an LED design: An edge-lit design that is thin and functions like a conventional CCFL backlight, or a backlit LED-array that isn't as thin, but allows for precise control over lighting individual areas of the screen. In this review, we take a look at the Sony 46" backlit LED-array HDTV, model 46HX929.

Toshiba 55ZL2 4K LCD 3D Display

Ofer Laor

When Toshiba announced the idea of a glasses-free 3D display, I was less than enthusiastic. I have been seeing lenslet based 3D glassless displays for a few years (mostly in the B2B and Digital signage spaces) and they were far from ready for consumer prime time. Now, Toshiba has announced their 55ZL2, which is a 55" LCD 3D display that has 4K native resolution. It's a first generation produce. How did it work with 4K video material, and does native 4K resolution improve the clarity of 1080p?
