What Is The Difference Between LCD And LED Televisions?

Looking for a new television can be a confusing experience. With all of the latest TV technologies, it can be difficult choosing the best TV for you. Two types of televisions that people will often compare are the LCD TV and LED TV. The following is a brief guide on the difference between an LCD and LED television to help you make your television selection.

Technically speaking, LCD TVs and LED TVs are both LCD TVs. The screen on both types of TVs is a liquid crystal display. The LCD television is a flat-panel television. With a LCD display, there are 2 layers of polarized glass which are joined together. The liquid crystals are contained in one of the layers. The liquid crystals pass or block the light to display the television image. The crystals do not produce their own light. The light comes from fluorescent lamps that are located at the back of the screen. Arranged in a grid are millions of shutters that open and close to release light and capture light that is not needed to produce images. Each shutter is paired with a colored filter which produces a sub-pixel. The sub-pixels are so tiny that when they unite they produce a single pixel. It displays as a single speck of color on the screen. Along with the assistance of fluorescent lamps, the television images that we view are created. LCD television can be quite thin and create high quality images. These TVs take up less space and they can even be hung.

LED TV's also have a flat-screen and use Liquid Crystal Display technology. However their source of light is different. LED TV uses Light Emitting Diodes LED. There are two types of LED back-lighting - Edge lighting and Full-Array lighting. The Edge lighting utilizes a series of diodes are that are arranged along the exterior edges of the screen. The light is dispersed across the screen. Full-Array lighting involves a number of rows of diodes behind the entire surface of the screen allowing for more control over dimming and brightness as the diodes can be switched on and off.

If you are not familiar with the current TV technologies, it can be difficult understanding the choice between LCD and LED televisions. Although LED TV's and LCD TV's both use Liquid Crystal Display technology, the key difference is that the LED TV uses Light Emitting Diodes while the standard LCD TV uses fluorescent lamps. When it comes to LCD TVs, Edge-lit television sets are normally lighter and thinner than a Full Array because the lighting source takes up less space. Full-array television sets are thicker and heavier, but one section of the LED panel can be dimmed while other sections stay bright which improves blacks and contrast in the television image. Edge lighting television sets are the lightest and thinnest TVs on the market.

LED TVs are more expensive than LCD televisions. Each type of television has its own advantages and disadvantages. The choice will depend on your needs and television preference.

What's the Difference Between a Reconditioned and a Refurbished HDTV?

So, you've heard about the latest buzzword: reconditioned and/or refurbished HDTVs. You sometimes see the word refurbished and sometimes reconditioned (and sometimes even the word used or second hand). You probably want to know the difference between reconditioned, refurbished, and used items. In this article I will explore that and also what a refurbished HDTV is.

Well, truth is, there is no real difference between refurbished and reconditioned. ("Used" is a different story. I'll get to it later on.) It's just that different retailers use slightly diverse terminology. Just make sure that it says the word factory before, as in factory refurbished and factory reconditioned. That means that it was repaired (if needed) and tested by factory trained personnel using original factory parts.

Many items get returned to retailers within the first 30 days. There are many different reasons for returns. Sometimes the partner doesn't approve, or it's not what the buyer expected. It might be too big, too small, not the right color, not the right size, etc. Or, it might even be broken. Whatever the reason, once it was opened and returned to the store (even if it was returned the same day for being the wrong color), it cannot legally be sold as new.

So the retailer sends it back to the manufacturer, where it is inspected. After fixing any defect, the refurbished HDTV is thoroughly tested and then repackaged. It must meet the same stringent quality-assurance standards that a new TV meets. And it usually comes with manufacturer's in-home warranties.

On the other hand, a used TV means just that "used"; a TV that has been used and the owner wants to sell it. This is the same as second hand. I wouldn't recommend buying it, though if you personally know and trust the seller, and it's for a ridiculously low price, you might consider it.

A factory reconditioned or refurbished HDTV however is safe to buy and usually sells for huge discounts. When you buy a refurbished HDTV, you get a quality, name brand TV for an incredible price.

Knowing the difference between LCD, Plasma HDTV LCD, OLED and

There are many emerging technologies in display devices such as televisions. Each technology is characterized by certain features of the display and is a particular method of representation. different technologies used in televisions

LCD TV:

Hd Tv

LCD (Liquid Crystal Display) televisions are thinner and lighter and offer much sharper and clearer the screen size of CRT. They are ideal for display on your phone, computer monitors, and photo viewing. LCD TVs have a flat so weno image distortion and have no windows "burn in" as curved tube TVs. In general, the angle of the liquid crystal is 175 degrees. The image can be 87 degrees on each side. LCD TVs are very economical to use and less than 35 screens are cheap enough. LCD TVs are backlit and block outside light. So are suitable for situations of natural light. Most LCD TVs have a half-life (50% of original brightness) of 30,000 hours (16 years, more than 6 hours per day). LCDSizes generally in the range of 13 to 65, but some manufacturers offer up to 100 variables.

Plasma TV:

A plasma display panel (PDP) is a large flat-screen television displays are used. You have to do better and more accurate colors than the generation LCD display with wide viewing angle, and not to degradation at high angles than LCD. Plasma displays are ideal for viewing moving video to large displays.

• Dimensions plasma usually in the range 32-84but some have screen sizes up to 100
· Technology pixel plasma offers a brighter image with more contrast between white and black as standard TV.
• In general, plasma TVs viewing angles of 160 degrees to 180 degrees and the images can be seen from every angle.
• In an average plasma TVs have a half-life (50% brightness) of 50,000 to 70,000 hours (20 years, which is 6 hours per day to 50,000 hours).
Some plasma televisions are equipped with updatedGraphics cards, which helps to match the technology of the future.

HDTV:

HDTV or High Definition Television is a digital television broadcasting system provides greater resolution than standard television systems. HDTV is digital broadcast program, in contrast with previous analog because digital television (DTV) signals require less bandwidth video compression, because digital.

HDTV is not a standard TV system problems, such as low qualityproblems of sharpness, brightness and contrast, patch, other visual or audio imperfections, problems such as double images (ghosting) and weak signals. HDTV offers clearer images with excellent sound quality, a larger screen and up-to-date scanning. Experience HDTV channels and more available than the system provided by satellite or cable with the normal theater.

LED-TV:

LED (Light Emitting Diode) TV is an LCD TV that uses LEDs for the rearLighting rather than fluorescent tubes (as it produces more black spots). They are ideal for indicators of low energy used to replace traditional light sources for general lighting and automotive.
· LED TV which currently cost more than a standard LCD or plasma TV.
· LED TV has been good and seems very easy to install.
· TV Edge-lit LED consumes 30-40% less than LCD or plasma. But LED backlighting and consume morePower.
· Light LED TV picture can be compared to a standard LCD TV to consider.
· LED TV that has a backlight with local dimming RGB LED and have a more extensive and better contrast and color accuracy than conventional LCD TVs.
It has a long life and environmentally friendly.

OLED TV:

OLED (Organic Light Emitting Diode) television employee light-emitting polymer technology. His property, including,
• In OLED TVs,do not need a backlight or additional heaters or coolers, so there is less power consumption.
• How OLED materials has the ability to support full spectrum of visible light, so that a higher contrast and is the frame rate at high speed.
OLED · are much faster than LCD. Time Lapse and rapid eye movement images are more realistic. OLED TV and virtual images look more realistic and can be easily observed for a longer period.
· There must be greaterAngle of vision for near-eye applications, it offers comfortable, without distortion.
A disadvantage with OLED TV is the limited lifetime of organic materials used in their manufacture. In addition, the blue light rapidly degraded with a life of 14,000 hours (8 hours per day for five years) for flat panel displays.

Before you buy a television, know the difference between the technology and buy one, the features you want and suitsYour budget.
