LCD TV comes in the design called Twisted Nematic (TN). It is a naturally twisted crystalline structure that reacts to electric currents by untwisting to varying degrees depending on the voltage of the current to which it is exposed. These TN crystals are stuck between panes of polarized glass and the untwisting allows different amounts of light to pass through. Basically, LCD displays can switch between light states (where the liquid crystals are fully twisted) and dark states (where the liquid crystals are fully untwisted), or somewhere along the gray scale in between. The TN liquid crystal is the most common type of liquid crystal being used in display applications today, including LCD TVs and monitors.

A LCD display consists of millions of liquid crystals, or pixels, that are manipulated to form images. Pixels are turned on by disabling the passage of light and turned off by enabling the passage of light, therefore creating an image in front of the viewer. A florescent bulb emiting white light through the transparent panels in a LCD TV. When all liquid crystals are completely twisted and therefore able to direct the full spectrum of light out through, you will see the white display. Color filters are used for color production in the LCD TV. To establish the color, each pixel is divided into three subpixels, red, green, and blue, working together to create the LCD pixel's overall hue.

I hope the above brief overview will help you better understand "how does LCD TV work."

There is no limit to the different styles and sizes of LCD TVs manufactured today, all of which are created by leaders and pioneering companies in the television industry. A consumer may want to check out different LCD TVs from manufacturers like Samsung, Panasonic, and Phillips, but there are also LCD offerings supplied by manufacturers like Sony, LG, Westinghouse, and Vizio too. Among the latter selections the consumer will see there are hundreds of variations in terms of cabinetry, screen sizes, an internal features.

Answering the question, “What is the best LCD TV,” begins by considering feature offerings and what the consumer wants. Knowing about an LCD TVs viewing angles, resolution, sound quality, picture quality, image enhancing features, and color quality are the first step in getting a great LCD TV. Examining reviews of select LCD TVs can prove revealing too as such reviews can explain the myriad features and the quality of LCD features to the consumer.

Ultimately, the consumer decides what is the best LCD TV. If the television delivers the precise resolution, viewing potential, screen size, structural design, and great picture quality the consumer is likely to be happy with the LCD TV selection. Of course, one of the most significant considerations is that of price. Consumers will need to spend some time checking out various LCD suppliers if they desire an affordable LCD television. It’s a good idea to check out Internet offerings in the quest for a good price on LCD television offers. Buying an LCD TV online usually can save the consumer quite a bit of money.

Determining the answer to the “LCD vs Plasma which is better” dilemma is not as complicated as it might first seem. If the consumer readily asks himself a few questions before television shopping, he or she will be better able to decide whether an LCD TV or plasma TV is the right buy for him. There are several questions that the consumer will need to reflect on before they begin seeking the LCD or plasma TV they desire at a good price.

First, the consumer needs to know what type of screen size in a television he or she is seeking. LCD TVs are offered in a range of different styles, cabinetry and sizes. Usually LCD TVs are thinner and lighter than plasma of the same size, making them more portable and cheaper to ship and install. Until recently, Plasma is considered as the favorite for larger screen sizes 42 and up. However, thanks to the advancement in LCD technology, LCD TVs go up to over 65" wide today. In fact, when comparing LCD offerings with plasma offerings, one will find that picture resolution is better delivered by LCD TVs comparing to Plasma.

Now more and more families are opting to a HD (high-definition) ready TV unit. Both plasma and LCD TVs display HD signals for a sharper, more three-dimensional picture. LCD TVs, however, have a slightly higher-resolution (more screen pixels) than plasma TVs.

As for color accuracy, Plasma TVs produce a more colorful picture than LCD TVs. Plasma color accuracy will prevail in rooms with low to normal lighting, while LCDs will be better in brighter rooms due to their inherent anti-glare technology. However, when it comes to viewing angles, longevity and energy savings, LCD TV is definitely the winner of the two. Plasma TVs have a screen life of about 30,000 to 60,00 hours, while LCD TV's have a screen life of 60,000 hours or more. In addition, Usually LCDs consume about half the power that plasma TVs consume.

LCD TVs today are now created with special, innovative technologies for motion enhancement too. A 120 Hertz LCD TV is highly recommended for those consumers seeking an LCD that is comparable to plasma TVs offering high motion control and quality imagery. One will pay a bit more for such technologies, but if the consumer finds it affordable, an LCD TV is indeed a quality selection.

In truth, the answer to the question “LCD vs plasma which is better", is really based upon consumer preference. Both television styles have their unique advantages. The consumer will need to consider style factors along with affordability factors in order to make an appropriate selection.

LCD television ratings and assessments make it easy on the consumer to know precisely how one LCD TV varies from another. LCD television ratings and reviews will commonly make mention of the various features every LCD TV under assessment has to offer. For example, an article presenting LCD television ratings might examine what types of tuners are integrated into the LCD TV housing, what the resolution of the LCD television set is, what the aspect ratio is in the set, and if the LCD television offering supplies the consumer with personalized setting options. LCD television ratings also assess the adaptability of color temperatures, the contrast ratio, the inputs that the device contains, as well as the quality of the sound system and output offerings. A full examination of available specs through LCD television ratings and assessments gives consumers a full understanding of what beneficial attributes are assigned to various LCD TVs.

Scanning various reviews of the latest LCD TVs gives the consumer instant access to the latest LCD television ratings. Understanding the benefits assigned to various LCD purchases, the consumer can then make an empowered LCD TV buying decision, and can feel less overwhelmed by the entire process. The reviews on LCD TV selections can help consumers sift through all the technical jargon and to get to the heart of the matter: what an LCD has to offer. Such reviews can also allow the consumer to assess whether or not the LCD TV in question is really worth the cost associated with the set as well.

This is a good questions, and the answer will depends on your own particular needs or preference. Now let's compare these two types of popular TVs first:

RESOLUTION
Winner: LCD
LCD HDTV displays usually have a higher-resolution, and therefore produce a sharper image than plasma of the same size comparison. For instance, the lowest resolution of a 40 inch LCD will be 1366 X 768 - easily full HD resolution in 1080i or 720p. A 42 inch HD plasma has a resolution of 1024 X 768.

COLOR ACCURACY
Winner: Plasma
Plasma TVs produce a slightly more colorful picture than LCD TVs. This is due to the fact that plasma TVs display blacks better than LCD TVs, which creates better color contrast, and produces brighter colors. Plasma color accuracy will prevail in rooms with low to normal lighting, while LCDs will be better in brighter rooms due to their inherent anti-glare technology.

SCREEN SIZES
Plasma TVs come with screen sizes ranging from 32 inches to 63 inches. Until recently, Plasma is considered as the favorite for larger screen sizes 42 and up. Thanks to the advancement in LCD technology, LCD TVs comes as small as 2" wide and go up to 65" wide today. LCD TVs are thinner and lighter than plasma TVs of the same size, making them more portable and cheaper to ship and install.

VIEWING ANGLES
Winner: Plasma
Plasma usually has up to 178° viewing angles, which is about as good as horizontal and vertical viewing angles get. LCD has up to 175 LCD ° viewing angles. However, LCD TV screens has the edge, although only by a very slight margin. On the other hand, Plasma images don't suffer from the same degration at higher viewing angles that LCD TVs do because of the different technologies utilized.

LONGEVITY
Winner: LCD
Plasma TVs have a screen life of about 30,000 to 60,00 hours, depending on the make and model, while LCD TV's have a screen life of 60,000 hours or more. In addtion, LCDs last as long as its backlight does. Plasma, on the other hand, utilizes slight electric currents to excite a combination of noble gases, which is an essentially active phenomenon. So the phosphoric elements in plasma displays fade over time. That's why Some Plasma owners who have used their TVs for a few years now have already witnessed the dimming of their screens.

HIGH-DEFINITION

Winner: LCD
Both plasma and LCD TVs display HD (high definition) signals for a sharper, more three-dimensional picture. LCD TVs, however, have a slightly higher-resolution (more screen pixels) than plasma TVs.

COMPUTER USE
Winner: LCD
LCDs display static images from computer or VGA sources extremely well, while Plasma have some issues with each source varying on different models and manufacturers.

GAME USE
Winner: LCD
Plasma TVs can experience screen "burn in" caused by static images. This happens when the still images is left too long on the screen, resulting an after-image ghost remaining permanently on the screen. LCD TVs do not have this problem and are therefore a better choice if you want to buy a TV to play video games.

ENERGY SAVING
Winner: LCD
LCDs require substantially less power to operate than plasmas do because of the different technologies they use. Usually LCDs consume about half the power that plasma displays consume.

PERFORMANCE AT HIGH-ALTITUDE
Winner: LCD
High altitudes can affect the performance of plasma TVs, because the gas held inside each pixel is stressed, and has to work harder to perform. Some manufacturers make plasmas that are specifically designed for high-altitudes, but they may be priced higher than standard models. LCD TVs, on the other hand, are not affected by high altitudes.

So to sum up, it seems LCD TV wins the contest "LCD vs Plasma: Which is Better", although we have to admit that each has their own characteristics. So whether to buy a plasma or an LCD will depend on your personal taste and preferences.
