Characteristics of LCD and Plasma LCD TV – Understand and Decide!
Year in and year out, there have a lot of models introduced in the market. Samsung LE40A786R2 LCD is a 403 wide screen LCD, Panasonic TX19LXD8 LCD Television, and SHARP LC-37D5U 37″ LCD are among the models newly manufactured. Hence, contemporary Televisions have totally outmoded the conventional Cathode Ray tube. At present, instead of the latter, the newer televisions have greatly invaded the abodes of customers during the previous years. LCD TV and Plasma TV are the most loved and admired TV choices by consumers at this moment, hence, regarding them as the two highly significant forms of contemporary TVs.
Plasma TVs are operated by a fluorescent bulb and its images are created by neon-xenon gases. In contrast, LCD TV is a slim, flat gadget which has two glass panels whose light are sourced from outside. Sandwiched in these panels are liquid crystals. The manner of selecting between these two Televisions, several features are very much important. How long will the TV last? Does it provide a good image quality? How about the power expenditure? These queries need responses and they shall be discussed together with some other factors. Surely, you will be given a general idea of the advantages each television have.
Viewing Angles – Plasma takes the lead in this feature as it provides numerous comfy angles while viewing.
Image Quality- Undoubtedly, Plasma TV provides a more superior image quality as compared to LCD Television since the pictures screened in the former are clearer and more detailed.
Display Resolution – Undeniably, Plasma and LCD TVs are capable of Hi-definition depending on the screen resolution. But if we try matching both up, LCD TVs will win over Plasmas considering screen resolution.
Screen Burn-Ins – This is a dilemma suffered by Plasma TVs. Hence, said TV is not a proper to select of you desire playing games with it.
Power Consumption – Who among the two absorbs lesser power? LCD TVs as against Plasma TVs. Hence, there is a little tendency that the gadget will heat up in a little moment. As for plasmas, heating up is one of its downsides necessitating fans to cool down.
Costs – After a thorough price hunt has been done, it was uncovered that huge plasma television sets costs lesser than its LCD counterpart. It is the other way around if the subject is medium or small sized TVs. In the latter case, cheap LCD TVs reign.
Some Other Points of Variation There are other features associated with both types of television sets that make them advantageous in their own ways. These features are compiles as follows:
Other than the aforementioned factors, the following are additional features which will highlight who between the two will reign:
o The Plasma TVs provide more superior motion tracking features than LCD TV.
o The LCD TV screens survive longer than plasma screens
o LCD televisions are slimmer and may be obtained in lesser weight as compared to Plasma TVs.
o Plasma televisions are manufactured at a large size which is not true in LCD TVs.
Therefore, after the aforementioned facts, it cannot be denied that the two contending televisions are market rulers having their unique and amazing features. If you seek a television, your preferences should be more superior to other influencing factors although the latter must still be present. Try searching also some consumer reviews so that you. You may also search for user reviews on the Internet while making a choice as to which you should by. Thereafter, enjoy all that your obtained TV can offer.

How a Plasma TV Display Works
A normal television works on the Cathode Ray Tube technology. In CRT TV a beam of negatively charged particles, known as electrons, fires up inside the glass tube. This beam of electrons hits the designated glass surface that has been coated with phosphor solution that emits various colors at varied intensities. The phosphor atoms lights up and thus produces the pictures.
For the past seventy-five years televisions have been working with this technology using the CRT. But the plasma TV display technology is very different and does not involve the CRT which is not only bulky but also very heavy and takes up a lot of space. Plasma TV is a product of high technology in its purest form for video display.
A Plasma TV with its flat screen display has quite different from the CRT TV technology. Apart from have a large screen it is less then six inches thick. The thickness is getting even thinner with more advanced technology. The technology used by Plasma TV and that used by CRT TV are quite different from each other. But the basic process remains the same; that is, they both deliver different lights at diverse intensities to create the spectrum of colors that we are so fascinated by.
The basic principle that works behind Plasma TV is lighting up of tiny fluorescent lights to produce the images. These tiny fluorescent lights are called pixels. These individual pixels contain three components of colors – red, green and blue. The individual pixel produces colors by mixing of these three basic colors. The brightness of the colors depends on the intensity of electrons that is hitting the pixels. These individual pixels together make up the whole screen and the intensity of the electrons hitting the pixels together make up the images on the screen. This is how the images are produced on the plasma TV screen.

What is Better – LCD or Plasma TV?
Which flavor of ice cream do you like better: chocolate or vanilla? The flavors are essentially the same but they’re also worlds apart when you compare the two part by part, aspect by aspect. And that’s what you’re facing as well when you’re shopping for a new TV. LCD or plasma TV? It’s a question that’s sure to set your head spinning if you don’t possess the right information.
What Makes LCD and Plasma TV Sets Alike
Before we get on with the various differences between LCD and plasma TV sets, let’s first take a look at the things they have in common.
To begin with, LCD and plasma TV sets are absolutely a better choice over CRT (cathode ray tube) TV sets. There are various reasons as to why both these new technologies are superior over the one that we had to make do with for generations. Firstly, LCD and plasma TV sets make use of flat screens whereas CRT TV sets make use of rounded screens. If you compare your viewing experience between the two, you’ll realize that you enjoy and see more with a flat screen.
Secondly, CRT TV sets are a danger to your health because it emits radiation while LCD and plasma TV sets don’t.
LCD and plasma TV sets can also display both standard and high-definition TV formatting. Whether you’re watching a program that uses normal or advanced formatting, you’re sure to enjoy them both with either a LCD or plasma TV set.
Prices are falling for both LCD and plasma TV sets. Although they don’t cost like peanuts, they are certainly much more affordable now so buying either one won’t be a pain to your pockets as much as they could have been if you had bought one in the past.
And there ends the similarities between the two. Now, it’s time to differentiate LCD and plasma TV sets from each other.
The Battle between LCD and Plasma TV Sets
Most of the differences arising from LCD and plasma TV sets are due to the different process each employs in producing high quality images in its screens. LCD TV sets make use of two liquid crystal panels that react to and against each other to display the appropriate images. Plasma TV sets, on the other hand, make use of a gaseous substance called plasma and which are contained in bubble-like cells of glass. Each glass contains RGB (red, green, and blue) phosphors. When electricity flows into these cells, the colors react accordingly to produce the appropriate images.
Brightness – If you’re looking for a TV set that can handle the brightest images, an LCD TV set may be more suitable than a plasma TV set. Brightness is often a concern for aging people as their eyes can only discern images accurately if they’re displayed in a brighter setting than usual.
Size – For near-sighted people, a larger TV set is better because it allows them to see images more clearly as everything is magnified by the screen. With regard to sizes, plasma TV sets can offer you more large scale options than LCD TV sets ever could. Generally speaking, plasma TV sets are built to be BIG while LCD TV sets are built to be compact.
Energy Conservation – Because of how LCD TV sets work, they will enable you to save more on electricity costs than plasma TV sets. But the difference between both energy costs is minimal so this must not be considered as a primary factor in the decision-making process.
Contrast Settings – How black is black, and how white is white? That’s the question you’re asking when talking about contrast. In a black-and-white movie, contrast is everything. Plasma TV sets will offer you better contrast than LCD screens. The margin between LCD and plasma TV sets is huge, so LCD TV sets are definitely second-best in this category.
Burn-In Images – Plasma burning is a somewhat common occurrence while burning is unheard of in LCD TV sets. But since manufacturers are continually come up with better and more effective ways to solve this problem, this shouldn’t be a primary factor in the selection process as well.
Ultimately, the choice is up to you. As cost is not a factor between the two, you’ll have to mostly depend on your opinion. Just as there’s no right answer between chocolate and vanilla, there’s no right answer as well for determining which is better between LCD and plasma TV.
