TV technology - LCD Vs Vs LED 3D Made Simple

LED TV


If you are not the small TV on the new technologies can be overwhelming when trying to understand and choose, are all possibilities. What is the best what you're looking for on a 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 good readingThe product information (which is barely understand) for the different models you interested in? 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

LCD TVs are televisions, liquid crystal display technology to generate images. These energy-efficient technology uses liquid crystal-filled cellssandwiched between two glass plates with a fluorescent 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 largeSizes.
• Energy Efficiency.
• 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 on an LED display is an LCD TV is the same story on the LCD. The main difference between the two is the different techniques, the backlight can change the image qualityProperties drastically.

Where LCD televisions use some form of fluorescent lamps, LED Light Emitting Diodes TV shows are the light of the LCD panel. Just as there are different types of LCD TVs in conventional fluorescent lamps, there are also various types of LED backlighting. 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 darkAreas of the image to get the backlight, that behind them in gray for improved contrast and black level. Other TV LED functionally similar to conventional LCD televisions. In this TV, LED lights are around the edge of the plate, which is a very thin depth, but without the ability to dim to the local levels.

Pros:

• thin, easily in large sizes.
• Increased contrast ratio - good image detail.
• Three-color LED provide morerealistic colors on the screen.
Edge environment '• "televisions consume less power than LED LCD TV.

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, togethertogether in a three-dimensional image in my head. Making screen 3D display of images based on a similar mechanism, but is divided into two categories - TV and stereoscopic television autostereoscopic (without options that seem to 3D) (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 imageare then processed by the brain to form an image in three dimensions in your mind.

TV autostereoscopic trust or parallax barrier or lenticular. 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 of a 3D shapeImage. parallax barrier is a grid of thin liquid crystal placed in front of the screen, with slits in it that correspond 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 viewsone.

Cons:

• image appears darker because less light reaches the eyes because of the glass.
• Glasses are 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 technologies such as TV, for functional reasons, response time, refresh rate, longevity and cost of the specific models you are interested in. But at least now can begin to inform your shipment!
