If you are not clued-up on new TV technologies, can be overwhelming when trying to understand and choose, are all possibilities. What is the best for what you see on TV? LCD, LED or 3D? If only the answer was so simple! Unfortunately, there are many types of each of the categories mentioned above, using a more verbose than the headings and subheadings to follow for sure, but it is no longer the only useful information on how to read the product (which is difficult) The understanding of the different models you are interested? Probably not! So we try to simplify the comparison of these technologies for those of us, not the guru of technology and pure that some basic, sound advice on our trip to the shop for our perfect TV.
LCD TV
3dtv
LCD TVs are televisions that use liquid crystal technology to produce images. These energy-efficient technology uses liquid crystal-filled cells sandwiched between two glass plates and place afluorescent backlight. The light is shone on the thin film transistor, which allow different amounts of light pass through the liquid crystal-filled cells. The liquid crystals are sensitive to light - the light that later become darker and more. The images are then displayed on the screen in black and white or in color, with color filters that the intensity of light produced by the LCD.

Pros:
• thin, easily in large sizes.
• Energyefficiently.
• Largely produced and available.
Cons:
• Lower the contrast ratio - less detail in darker areas.
LED TV
LED televisions are technically a member of the family of LCD-TV. The screen of an LED is a liquid crystal display, the same as any other LCD TV. The main difference between the two lies in the different techniques, the backlight of the image quality can change dramatically in properties.
In cases where a form of LCD TVFluorescent lamps, LED TV using the LED light on the LCD panel. Just as there are different types of fluorescent lamps with conventional LCD TVs, and there are various types of LED backlighting. In some TV LED is a panel of LED lights behind the LCD panel. These are three LED colors and can be controlled in the bank to an effect called "local dimming". This allows darker image for the back-light behind them that led to a better contrast and grayBlack levels. Other TV LED functionally similar to conventional LCD televisions. These televisions are LED lights on the edge of the plate, what a very thin depth, but without the possibility of local dimming.
Pros:
• thin, easily in large sizes.
• Increased contrast ratio - good image detail.
• Three-color LED provide realistic colors on the screen.
Edge environment • '"LED consumes less power than LCD TVTV.
Cons:
• expensive.
• "local dimming" LED TV consume more energy than LCD TV.
3D TV
A 3D-TV is a television that uses techniques of 3D presentation. To understand how you see a 3D image, we must understand that our eyes two separate lenses, which register the two images different angle of an object that is sent to the brain, together, and transformed into a three-dimensional image in mind. Making screen 3D display of images based on asimilar mechanism, but is divided into two categories - TV and stereoscopic television autostereoscopic (which appear 3D without options) (special glasses to see 3D images require).
stereoscopic television require the use of polarized glasses or both. Both types of glasses have the same primary mission - to use the lenses for each eye a different image, which are then processed by the brain to form a three dimensional image in your mind.
Autostereoscopic count on TVor lenticular lenses or parallax barrier. Lenticular lenses are tiny cylindrical plastic lenses that are inserted into a transparent film, which clamp down on the surface of the LCD display. The lenses magnify the images on the screen when viewing pictures of the new cylinder provides each look different 2D images are combined by the brain to produce a 3D image. parallax barrier is a grid of thin liquid crystal placed in front of the screen, with slits in it thatcorrespond to specific columns of pixel thin film transistor screen. These slots intentionally light from each image slightly different on each eye, forever in a 3D image of the brain.
Pros:
• High refresh rates provide regular and detailed.
• TV allow autostereoscopic parallax barrier can be turned on / off - 3D and 2D version of a.
Cons:
• image appears darker because less light reaches the eyes because of the glass.
• Glassesare uncomfortable and take the simplicity of television.
• autostereoscopic TVs have a "sweet spot" and display the image when the user changes from this point distorted.
• noted the risks to health, especially in children, pregnant women and elderly people.
This has to you, the consumer, in your decision to buy a TV? This is only a beginning to the process. Of course there are several things to consider when comparing TV technologies such as functionalConsiderations, response time, refresh rate, longevity and cost of the specific models you are interested in. But at least now we can begin to inform your shipment!
