When flat-panel TVs first started popping up, eager shoppers basically had two options: plasma and LCD TV. But in those early days, LCD TVs were tiny. expensive and didn't really look that great. What a difference 15 years can make. LCD TVs are bigger, brighter and more beautiful than ever, and also offer excellent value for your high definition television dollars.
It's a Liquid?
LCD isn't the type of liquid you'd want on a hot day -- unless you're enjoying a movie marathon next to some air conditioning. Otherwise, the way LCD works is fairly simple to understand. LCD is made up of two polarized glass panels. One has an array of liquid crystal pixels, which are typically made up of red, green and blue sub-pixels. The other panel is a polarized filter with no color component. Instead, it controls the intensity of light passed through it. Behind the panels, there is a light source, which shines through the LCD panel to make that pretty, bright picture.
LCD TV is often confused with LED TV -- and for good reason. LED TV is actually part of the LCD family.Both use LCD panels to produce an image with the only difference being the light source. A traditional LCD TV uses skinny fluorescent tubes called CCFL (cold cathode fluorescent lamps) as a light source, while LED TVs use an LED-based light source to illuminate the panel. For simplicity, we're going to limit this buyer's guide to standard CCFL-lit LCD TVs. For more information on LED TV models and technology, check out our LED TV Buyers Guide for 2012.
When it comes to TV technology, LCD is typically the least expensive flat panel you can buy, but that doesn't mean you can't find a nice high quality image and plenty of features. Panel response times, refresh rates, contrast ratios and color accuracy and saturation have all improved over the years as the prices continue to fall.
Dissecting the Specs
Those response times, contrast ratios and refresh rates are all something to consider when buying an LCD TV. Why exactly? Well, a response time is the amount of time it takes an LCD's panel to go from full black to full white, resulting in more realistic images. The lower that number is, the happier you'll be. Just remember that it's measured in milliseconds.
Contrast ratio is important because it measures the difference between a full black signal and full white. Unlike response times, you want a high number on the contrast ratio. That said, this is a bit harder to measure. Currently, there's no industry standard and some manufacturers list this number as a dynamic contrast ratio or a native contrast ratio, making the decision sort of confusing and hard to compare.
Finally, a refresh rate stands for the number of times per second that the screen image is refreshed. A higher number is good here, as well. It basically means that the TV can handle things like action and sports pretty well. Measured in Hertz, typical LCD refresh rates measure anywhere from 60Hz to 240Hz (60 to 240 screen refreshes per second).
LCD TVs aren't just the least expensive, but also come in all sorts of sizes. Whether you're looking to add a flat screen to the living room, bedroom, basement or even the bathroom, there's an LCD out there for you. This year, we're going to see LCD sizes ranging from 22 to 65 inches. Besides sizes, there are plenty of other goodies being offered on this year's LCD HDTVs. Let's take a peek at what manufacturers are offering in the LCD category this year.
