Plasma Vs LCD Vs LED TVs - What Are the Differences?

In the last 10 years, TV technology has advanced to a great extent and has brought in state of art technologies in providing the finest flat-screen TVs. The most important aspect of the technology used has mainly focused around the size, resolution and compatibility and with this, in the last 5 to 10 years there has been a gradual change in the choice and viewing expectations of people.

The manufacturers have now started to put in unique features in their flat-screen TV models making the product having a distinctive advantage of full film effect viewing along with outstanding sound technology. There are various types of flat-screen TVs in the market today, and in order that you could decide between Plasma, LCD, and a LED TV, you ought to know a bit about the differences.

Overview of Plasma TV: The display in a Plasma TV is made up of millions of tiny plasma cells, and to put it simply, these cells emit light to create a complete image on the screen when a precise voltage is applied to them.

Plasma TVs available now offer larger screen size than LCDs. The screen sizes of Plasma TVs that are commonly available in the market include, 30 inch, 42 inch, 50 inch and 63 inch models, while the lcd tvs are limited to smaller screen sizes, which range from 10 inch to 40 inch models. Presently larger screen sizes of more than 60 inches are being made available in the market. One favourable point is that, the LCD technology is more flexible, which allows wide variety of screen sizes to be developed.

Advantages on Plasma TVs:
- Plasma TVs are available in larger display screen sizes.
- Plasma has better black levels, and also the contrast ratio.
- Plasma TVs can be viewed from any angle, as long as the viewing angle is between 160 to 180 degrees. - Plasma TVs have top refreshing rate which captures every detail in a fast action scene.
- Plasma screen can display billions of colors, producing smooth gradations of shades, enhancing the picture quality to a great extent, making the images life-like and realistic, responding sharply to fast moving images.

Disadvantages of Plasma TVs:
- Plasma TVS do not perform as well at higher altitudes.
- Plasma TVs are more susceptible to burn-in of static images.
- Plasma TVS are thicker than lcd tvs and hence much heavier.
- Plasma TVs produce glare in brightly lit rooms though some advancement in technology has been made to correct this.

Overview of LCD TVs: LCD TVs have Liquid Crystal Displays, a technology which is seen being used in computer monitors, cell phones, and at times are found in camera screens. LCD screen was first created for computer monitors, and now with the application of the technology in LCD TVs, they seem to be a bit better when you are playing games on your TV. However, the choice entirely depends on the user, since some like the vivid colors in Plasma TV, which comes from its deep black levels.

LCD panels work with liquid crystal solution being sandwiched between two polarized glasses. When an electrical voltage is applied to the liquid crystal, the crystals rotate, and this changes the polarization of the light passing through them. A LCD panel does not generate light by itself. It just filters or subtracts its back light source to create an image on the screen.

Advantages of LCD TVs:
- LCD TVs have better longevity than the Plasma. The average life-span has been predicted as more than 30 years.
- The display of LCD TVs uses lower power compared to Plasma TVs, but has more consumption than LED. - The screen sizes of LCD TVs are available in various sizes starting from computer monitor screens to over 60 inches.

Disadvantages of LCD TVs:
- The TV has a very poor contrast level and responds slower to fast moving images, creating a blur.
- The prices of LCD TVs are higher than the Plasma, and because of the demand and increased production the prices are gradually falling.

Overview of LED TVs: The term 'LED' stands for Light Emitting Diode. It is an electronic component which emits light when a certain voltage potential is applied to its terminals. Though the TV using this technology is call LED TV, but the LED light source is used as the TV's backlight, while the TV screen is actually LCD. Though some current TV models use CCFL (Cold Cathode Fluorescent Lamps), LED form of backlighting remains a far more efficient TV backlight system.

The Advantages of LED TVs are as follows:
- With LEDs as the backlighting source, the TVs have a far better dynamic contrast level than LCD TVs, since it uses a direct backlighting technology.
- LED TVS are ultra thin as much as about an inch in thickness.
- The power consumption of LED TVs are less than the LCD TVs currently available.
- Out of the flat screen TVs available in the market today, LED TVs are considered to be most reliable.

The disadvantage is that LED TVS are higher priced than LCD TVs, but prices are expected to come down with increased production.

The above is an attempt to provide a basic conception about the differences between the three technologies available presently in flat-screen TVs which would help a buyer to decide which TV to buy.

Choose the Right Stand for a 42 Inch LCD TV

Unless you're mounting your new 42 inch lcd tv on the wall or on the ceiling, you'll need a solid and reliable stand to support it. Many TVs come furnished with an appropriate stand, but some require that the stand be purchased separately. If the manufacturer furnishes your 42 inch lcd tv stand, and it meets your needs in terms of styling, you're in great shape. Because your 42 inch lcd tv could become an integral part of the room's decorating scheme, though, you may choose to purchase a stand that matches the needs of your viewing habits, your home, and your sense of style.

Because a 42 inch lcd tv is reasonably heavy, the most important requirement is that any stand must handle the weight of your particular 42 inch LCD TV and must provide a stable base in case it's bumped or jarred. For that reason, make sure the stand you purchase meets the unique weight and strength requirements of the 42 inch LCD TV you purchased. The last thing you want to have happen is for your new TV to become damaged simply because your stand wasn't up to the task. The owner's manual for your 42 inch LCD TV will specify all the requirements of a suitable and effective TV stand for that model.

There are a few other considerations besides strength, though. Let's look at a few other decisions you'll want to make to ensure you get the maximum enjoyment from your 42 inch LCD TV.

1. Determine if the stand needs to hold other audio-visual equipment? If you own a DVD player, use a cable converter, have game systems like an Xbox or a PS2, and/or have a home theater system, you may want your stand to house that equipment as well as support the 42 inch LCD TV itself. Make sure you pick a stand that has shelves or compartments for the equipment you own, or even may someday own.

2. Determine if the stand will position your TV at an optimal viewing height. The height of the TV is an individual choice - make sure the stand you select will place your 42 inch LCD TV at the height you want. If you can, find an adjustable stand that gives you some flexibility. If not, determine the right height for you and select an appropriate height stand. An easy way to calculate your optimal height is to sit in your favorite chair or couch and determine how high your eye level is. Once you've determined eye level, make sure your 42 inch LCD TV will be centered at that point. Many stands are pre-engineered to approximate an appropriate viewing level for the average person, but make sure you're comfortable with that height before you make a purchase. Some pedestal stands are adjustable; if you don't need storage space, check out a pedestal stand.

3. Check to see if the stand has integrated cable management. If you're buying a cabinet with a closed back, cable management probably isn't an issue, since you'll have plenty of space to hide cables. If you're interested in a pedestal stand or a stand with an open back, make sure there are provisions built in to hide all the cables you may have. If you have a home theater, video gaming system, DVD player, and other components, you'll have a large number of cables running from component to component - make sure the stand gives you plenty of room to store those cables out of sight. The stand shouldn't just house your 42 inch LCD TV - it should handle all the cables and components, too.

Once you've found the right 42 inch LCD TV, finding a stand suits your needs and fits you're your room's décor and design is important, too. Make sure you can enjoy your TV while it's turned on, and how it looks when it's not turned on.

Samsung LED LCD TV Features

The term LED stands for light emitting diodes. It is a new technology that has replaced the use of standard florescent tubes in televisions. Samsung LED lcd tv uses this technology to produce extremely fine images.

Samsung TV has received the esteemed "Innovation Award" from the European Image and Sound Association because of its outstanding features and extremely high quality.

They are energy savers in that they use 40% less power as compared to the ordinary lcd tv that is of a similar size.
Due to local dimming capabilities the LED TV produces finer dark images by reducing the white light in the required areas.
The problem of viewing the TV from different angles is solved with the introduction of LED lights behind the LCD panels.
Price of LED LCD TVs is higher than the traditional LCD TV but the quality of the vibrant images that they produces enhances the viewing experience making the increased cost worth it!

Vizio 32 Inch LCD TV VU32L Review

The Vizio 32 inch lcd tv VU32L is a 720p widescreen HDTV ready television with 1080i capability.

The native resolution of this flat panel TV is 1366 x 768. Don't be disturbed that it is lacking the full high definition resolution of 1080p - on a TV of this size that resolution would be wasted, so Vizio has done consumers a favor by foregoing marketing hype in favor of providing sheer value for money.

- Lamp life of 50,000 hours
- Uses 60% less power than a conventional TV of the same size

What is lamp life?
The lamp life is the time span a TV will be able to display a picture before a half level of brightness is reached. In the case of the VU32L, it is rated at 50,000 which on average is equivalent to abo8ut 20 years of usage (more than just about anyone keeps a TV for). If you use your TV for less than 6 hours per day then you can expect an even greater lamp life.

Pros
There are so many good things about this TV. You will find that images are very sharp and crisp, with deep colors. The 3:2 pulldown feature comes in handy as well. The TV works well in brightly lit rooms.

Cons
Connectors are only located at the rear which could be a pain for some people.
