The Differences between HD TVs and LCD TVs

Unlike a few years ago when the only option available to anyone who wanted to buy a new television was the size of the screen today there are a few different types of TVs available. Many people choose the clarity and enjoyment provided by a HD TV but you may not be aware of the fact that these TVs do not have to have an LCD panel.

High definition

HD TVs can have plasma screens and as such they also have a number of different features that the LCDs do not have. Of course there are both disadvantages as well as advantages no matter which screen you choose to buy. Let's take a closer look at some of the differences that exist between the plasma screens and the LCD screens.

  • When it comes to brightness the Plasma TVs are usually far brighter than other types of TVs.
  • Plasma TVs are also more capable of showing black areas.
  • These TVs do not have internal speakers although they sometimes have an amplifier already installed. If you choose the plasma TV you will obviously have to connect it to your home theatre system. Because this is not much of a disadvantage many people to disregard it altogether.
  • LCD TVs have scan lines across the image and this is a nuisance plasma screens do not have. This is because they make use of transistor electrodes for each pixel and therefore your viewing enjoyment is all the more guaranteed.
  • Plasma screens are also able to accept signals from most computer systems and work with many old formats. The plasma TV will have no problem decoding signals like NTSC, SECAM, BNC, RCA and PAL.

In case you are not already aware of the fact HD TVs do not have to have a flat screen. CRT televisions capable of handling the 1080p/l or 720p signals can also provide HD quality. Bear in mind though that they are harder to find these days due to the popularity of plasma and LCD.

Lcd Television

Although different from the plasma screen the lcd televisions can and does display HD signals. Many people find they prefer the LCD television when it comes to high definition viewing which also includes gaming. Unlike their plasma counterparts the LCD TVs do not suffer from the infamous burn-in problems and so are much more able to handle still images for a longer period. Despite the fact that the LCD TVs do not offer images as clear as that of the plasma TVs they are still a great choice when you are in the market for a new HD TV.

  • LCD TVs use a technology that allows black and colored images to be filtered by white light that comes from a line of cold cathode fluorescent lamps housed at the rear of the screen. You will be able to see these when you look through the back air vents. Shutter open and close when necessary to allow a specific amount of white light to shine forth. The shutters are all fitted with color filters that remove RGB from the light. Although this is very simplistic it explains the reason why they are able to maintain an image.

  • All LCD TVs will have the recommended ports which include HDMI, VGA, Composite, Component, S-Video and audio out.
  • Some models have a USB port that is able to process different media types which is very handy.

As the above has illustrated there are differences between a standard HD TV and LCD TVs. Depending upon your specific requirements you will be sure to find what you need.
