Important Facts You Need To Know Before Buying A Television

Televisions (TV) are the most commonly used form of public entertainment. They are increasingly becoming an important part of our homes, offices, and public places such as airports, train stations, bus stations, etc. Televisions are used for watching TV, listening to music, for accessing the Internet, etc. TV sets are portable and can be carried around, while PC’s and laptops are stationary and cannot be moved.

Television (TV) has three components: video programming, audience feed, and audio/visual equipment. Televisions are built on circuit boards called TFTs or Thin Film Transistor technology chips. These chips can support liquid crystal display, LED, or LED backlighting, or resistive or polarised LCD displays. In the past, cathode ray tube TVs (CRT) dominated the television market. Now, due to the widespread availability of Freeview Satellite TV services, many people prefer to watch TV on the move or with their laptops.

When a television is switched on, it draws power from the local electricity supply and converts it into electrical signals which are later sent to the television set. In the USA, the majority of Americans have access to Freeview satellite TV. Satellite TV is usually delivered in the form of a Freeview TV box, small TV receivers, DVR cards, or PC satellite TV software. Satellite TV offers a range of special features that are not available with other kinds of television. For example, Freeview TV lets the television user select his own weather forecast, whereas other kinds of television are dependent on the weather forecast provided by various channels.

The quality of the picture is dependent upon three factors: picture resolution, colour depth, and contrast. Picture resolution is measured in terms of pixels, and it is the number of pixels per inch. Hence, the higher the pixel resolution, the clearer the picture will be. Pixels can also be referred to as texels, which are very tiny dots.

Generally, LCD TV’s and Plasma TV’s have similar image resolution, but the level of image resolution is different between the two types of TV. LCD TV’s have better picture resolution than plasma TV’s because LCDs have much better pixels per inch than plasmas. However, plasma TVs always perform better than LCD TV’s when it comes to colour depth. The depth of the picture is measured in pixels and each individual colour within an image is assigned a particular number of pixels. When the depth of the picture is greater than 300, this is referred to as ‘deep colours’ and it gives a richer, more realistic look to the picture.

The amount of detail is another factor that affects the quality of the picture. As a result of the HD resolutions, today’s televisions can show much more detail than previous televisions. However, it is important to note that the picture resolution of a TV does not necessarily correlate to the amount of detail presented on the TV screen. So, for example, if you watch a movie on a plasma TV, it may have a greater amount of detail than on an LCD TV. Another thing to keep in mind is that HDTV’s can also compress the digital signal that is transmitted over channels so your picture may appear blurred if the signal has a high modulation level.
