The differences between LCD TV with LED backlight and CCFL

LED televisions are a member of the family of LCD-TV from a technical point of view. The screen of an LCD TV is an LCD display similar to other LCD TVs. The main difference between the two is the different lighting techniques that change the characteristics of image quality dramatically.

While conventional LCD TVs use such as light bulbs called Cold Cathode Fluorescent Lamp (CCFL) for those using TV-emitting diodes instead of LEDs. The result of using LEDsis a more dynamic contrast, darker blacks and whites whiter means. Especially black most often as a dark gray on normal LCD TV. Since LEDs are very low, in many cases, this leads to a leaner and TV. You're also saving energy than CCFL and often below the requirements of Energy Star label, which remain a positive impact on the bill ' electricity as well. There is less pollution when recycling them as well.

LEDs have disadvantages and small,depending on the method of adjustment. During the beginning of a new line called TV fine-tuning often use local dimming prone, older models are edge-lit only. Even better, the CCFL, but it creates the lighting in this way is not entirely homogeneous.

Always remember that the quality of the display, or LCD or LED LCD backlight depending on the amount varies with the size and manufacturer. It is always advisable to see an electronics store nearIt also if you plan to buy a new TV on the Internet. leading brands often offer a better service than unknown foreign manufacturers, so you think that money and image, the only factors.

explain the differences - VS LED LCD vs Plasma TV

the last 10 years, many new flat-screen TV technology have been marketed in one, all with very good improvements over the previous technology. The rapid advances in technology have allowed many of us behind, like most of us do not graduate in electronics. So what are the main differences between these new TVs?

Plasma TVs

These are the oldest of the new flat screens. They arrived at about the same time as LCD TVs, but they were veryexpensive for their size, so they were more popular in the introduction. The plasma screens with a gas that turns into a plasma when an electric current passes through the emission of light.

Plasma professionals:

- Less expensive than other flat screens for the same size.

- In general, better, more realistic colors than LCD TVs.

- The deepest blacks and the contractual relationship than LCD TVs.

- Do not suffer from motion blur. Plasma displays have fast refresh rates, so movingObjects appear less blurry.

- Larger viewing angle of LCD TVs.

Plasma Disadvantages:

- Life less than other flat screens. The plasmas are expected to last 10-15 years, while the LCD TVs that take two or more times.

- Plasma uses more energy to function.

- Not available in all sizes (not in small quantities and only in a couple of sizes set, for example, 42 inches, 50 inches, 60 inches) ..

- Normally, a little 'thicker and heavier than the others.

- In case of moreprone to reflected glare in bright rooms.

LCD TV

LCD panels for the first time the existence in the form of computer monitors. The same technology has for many years. It 's the same basic technology as the screen of a pocket-calculator. LCD TVs generally refers to a fluorescent backlit LCD TV. This is not to be confused with the TV LED LED with most recent, which is technically still an LCD TV with the exceptionBacklight technology.

Advantages:

- A better life than plasma screens. life expectancy of 30 years is possible.

- LCD screens consume less power than plasma, but most of LED TV.

- There are many sizes of computer screens up to 60 + inch screens.

- Lighter than a plasma, thus easier to mount on the wall.

- While prices of LCD TVs were higher than the plasma, which is falling rapidly with increasingProduction.

Disadvantages:

- Worst-panel in terms of performance: low contrast and slow (motion blur possible).

- Narrow viewing angle possible, with slight variations in color for a particular audience.

LED TV

LED LCD TV is actually technically, but with LED backlighting instead of fluorescent lamp / s. This technology is the next generation of LCD screens.

Differences between the LED backlightCurrent LCD technology:

- A LED backlight produces far greater dynamic contrast because of its direct backlight.

- LED Television can be made extremely thin, about an inch thick on top.

- TV LEDs consume less energy of all three types of screens.

- Television is currently much more expensive than LCD, but prices should drop dramatically as increases the production of LEDs.

- TV LEDs are more reliable than anycurrent flat panel systems.

I hope this makes finding a suitable TV for a more easy!
