Lcd TV:

Lcd (Liquid Crystal Display) televisions are thinner and lighter and provide much sharper and clearer picture than CRTs of similar size. They are ideally used for cell phone displays, Computer monitors, and to view still images. LCD TVs have a flat screen so there will be no picture distortion and don't have screen burn in "like curved tube TVs. In general, LCD viewing angle is 175 degrees. The picture can be viewed 87 degrees from each side. LCD TVs are very economical to use and screens less than 35 are fAirly inexpensive. LCD TVs are backlit and blocksoutside light. I know, they are suitable for natural lighting situations. Most LCD TVs have a half lifespan (50% of original brightness) of over 30.000 hours (16 years of viewing at 6 hours per day). LCD sizes generally range from 13 to 65 but some manufacturers will offer up to 100 sizes.

Plasma TV:

A Plasma Display Panel (PDP) is a flat panel display used in large TV displays. They have better and accurate color generation than LCDs, and with far wider viewing angles, display, and do not experience degradation at high angles compared to LCD. Plasma displays are ideal for viewing motion video in large displays.

· Plasma screen sizes generally ranges from 32 to 84 but some offer screen sizes up to 100.
· Plasma pixels, technology provides a brighter picture with more contrast between the blacks and whites than standard TV.
· In general, plasma TVs viewing angle is 180 degrees to 160 and picture can be viewed from any angle.
· On an average, Plasma TVs have a half lifespan (50% of brightness) of 50.000 to 70.000 hours (20 years of viewing 6 hours a day to 50.000 hours).
Some plasma TVs are provided with upgradeable video cards that helps to match with future technology.

Hdtv:

Hdtv or High-Definition Television is a digital television broadcasting system offering a higher resolution compared to regular television systems. Hdtv is digitally broadcast unlike earlier analog broadcasting, because digital television (DTV) signalsrequire reduced bandwidth because of digital video compression.

HDTV standard TV will not have problems, like low quality sharpness, brightness or contrast with troubles, spots, other visual or audio YouTube girls, problems like double images (ghosting), and weak signals. HD television provides clearer pictures with excellent sound quality, a wider viewing screen and up-to-date scanning. HDTV will provide more and superior channels provided by regular satellite or cable television with theater system experience.

LED TV:

LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for back lighting, instead of using the fluorescent lights (as it creates more black spots). They are ideally used for low-energy indicators, as substitutes for traditional light sources ingeneral lighting and automotive lighting.
· LED TV currently costs more than a standard LCD or plasma TV.
· LED TV has got great looks and very easy to Install.
· Edge-lit LED television will consume 30-40% less power than LCD of or plasma TV. But backlit LEDs will consume more power.
· Brighter picture can be viewed with LED television compared to a standard LCD TV.
· LED TV that is backlit, with local dimming and RGB LEDs, will have an enhanced picture and better contrast ratio and colour accuracy compared to standard LCD TV.
It has a long lasting life and also eco friendly.

OLED TVs:

OLED (Organic Light Emitting Diode) TVs depend on light emitting polymer technology. Its featuresincluding,
· In OLED TVs, there is no need for backlights or extra heaters or coolers, so there is less power consumption.
· As OLED materials has the capacity to support the full spectrum of visible light, so there will be higher contrast and it has high-speed refresh rates.
· OLEDs are much Faster than LCDs. Fast motion and quick eye moveMent pictures are more realistic. OLED TVs will make And virtual images to look realistic and can be viewed easily for longer periods.
· It has larger viewing angle and for near-eye applications, it provides more pleasant viewing without distortion.
One disadvanTAGe with OLED TVs is the limited lifespan of the organic materials used in its manufacturing. In addition, blue light degrades quickly with alifespan of 14.000 hours (8 hours when used per day for five years) on flat-panel displays.

Before purchasing a television, know the difference between each technology and purchase the one, which has your desired features and suits your budget.

What's the Difference Between Plasma TVs and LCD TVs?

Plasma and Lcd TVs are the latest trend in home entertainMent. Both offer unrivalled picture quality and resolution, while doing away with the bulkiness of the older rear-projection technologies. But with all of the hype surrounding these two types of televisions, what is the difference between them? Although they look-and are virtually priced-the same, they are not.

What's the Difference Between Plasma TVs and LCD TVs?

There are differences in the way in which they display their pictures. Plasma TV technology is made up of hundreds of thousands of little pixels, each capable of displaying red, green, and blue colors. A plasma monitor often consists of two panels, which are filled with an inert gas, such as neon or xenon. When the pixels are excited by pulses of electricity, the gasbecomes liquid, thus generating light. This light in turn then illuminates the pixels, causing them to display the appropriate color to form a picture.

Lcd panels function in a very similar manner. A panel of thin-film-transmitters, or TFT, sends electricity to cells filled with liquid crystal. When the cells are struck by the electricity, the liquid crystals allow light to Filter through. Unlike the pixels found in plasma TVs, Lcd monitors create color by blocking out the appropriate wavelengths from white light.

So which is better? The answer to this question depends upon what you plan to use for TV. Do you just want to use it to Watch movies and television? If so, then a plasma TV might be best, because they are capable of a higher better colorsaturation and contrast than their Lcd counterparts and for displaying moving images. If you plan on spending a lot of time showing digital photography or plan on using the monitor with your Computer, then LCD display might be better suited to these purposes.

Both plasma and LCD technologies each have their advanTAGes and disadvanTAGes and your decision should ultimately be based on your monitor's application.

The Difference Between Wants & Needs

The Difference Between Wants & Needs

So you want to become wealthy? While there is no single road to getting there, it's a sure bet that one principle is in place for those who keep their wealth over a lifetime. Live beneath your means. Spend less than you make. Don't spend more than you can afford. It doesn't come any simpler than this. If you want to create wealth, you have to learn to do this. It doesn't matter if you make ,000 a year or million, if you don't learn how to master the step of spending less than you earn, you'll never create lasting wealth.

While the concept is simple, chances are you are not following it. In all likelihood, you are living paycheck to paycheck, treading water. No matter how hard you try, you never seem to get ahead. Even when the raises come, the money still disappears just as Fast. If this sounds like your situation, you probably have not mastered the difference between needs and wants.

First, it's important to realize that wants and needs are not the same. When you read that sentence, you probably said to yourself, "Of course, everyone knows that." Again, while everyone may know this intellectually, it is a good bet that you aren't completely honest with yourself when it comes to the things you purchase.

How many times have you heard (or for that matter said yourself) "I absolutely need (fill in the blank)" when in reality the meaning was "I really want (fill in the blank)?" I can't live without those shoes...I will die if I can't have that ring...I simply have to have that car...the list can go on and on. Please don't get me wrong. These are phrases that we all use. That is why it's important to step back and remember that wants and needs are not the same.

It's important at this point to make clear that taking the time to critically look at your current lifestyle and what are the true needs versus those things that are convenient wants will go a long way in saving you money and enabling you to spend less than you make. Let's take an example of your TV. Is your TV a need or a want? Although I can hear the arguMents already rationalizing why a TV is a necessary part of your life, the truth is that it is more than likely a want. In most cases, it is probably an affordable want (The exception may be if you decided you had to have that 50 inch state of the art plasma television with the price TAG of a small car). The question is whether the digital cable TV, 6 premium channels, satellite dish, the on demand movies, the DVD player with movie selection, etc are all also affordable wants?

Here is a list. Take a few moMents to jot down what is a need and what is a want.

shoes designer suit water large apartment bed ice-cream lottery tickets car entertainment center club membership lunch concert tickets trip to Hawaii medicine necklace Computer daily espresso cellular phone golf clubs furnishings

Unfortunately, the answers to these questions are not completely black and white. What may be a want for one person may be a necessity for another person. For example, let's take a look at a Computer. If you make your livelihood on the Computer, then a computer is a necessity for you. If you only use a computer to play the latest online games, then it isn't. Knowing this, we can still make some pretty good guesses as to what are wants and what are needs from the above list for most people. Shoes (and Clothing in general), water, bed, car, lunch, medicine and furnishings are good bets to be needs. Now that doesn't mean that the latest model, 4 wheel drive sport utility vehicle with all the extras counts as a need for most people, but basic transportation to make a living does.

A large apartment, computer and cellular phone may or may not qualify as a need depending on your particular circumstances while a designer suit, ice-cream, lottery tickets, entertainment center, club membership, concert tickets, trip to Hawaii, necklace, daily espresso and golf clubs all probably fall into the want section.

If you can take the time to start being honest with yourself, you will find that a lot of the things which you assumed were an absolute necessity until now are in reality nothing more than wants. Once you distinguish between the two and look at these issues objectively, you have placed yourself in the position to live within your means by simply asking yourself whether or not an item or service you are about to purchase is a need or merely a want.
