The TV is an important thing in the living room of most homes. In addition to their original purpose, which was to watch television, television sets have also become the medium for purchased and rented films, commercial industrial displays and games. There are some basic types of TV: Direct view TV, rear projection TV and HD TV. Included in the last two are plasma and LCD (LCD) models. Each of these has its own set of features.
This is an analog TV version and in earlier days it came with bulky cathode ray tubes on the back. Over time, several technical upgrades were made to this TV. They now come with less bulky backs and flatter screens compared to the previous bubble screens. This has resulted in a much clearer transfer relay. This form of television is still quite popular due to its cheaper price tag compared to digital TVs. In terms of benefits, the live view provides an excellent screen at prices that are significantly lower than their digital counterparts. The biggest plus point is that a viewer can see the screen clearly from any angle. They are also available in sizes from 9 to 40 inches.
Rear projection TV
The most important aspect of rear projection television (RPTV) is that they are large. Depending on sizes from 42 to 82 inches, these are large TVs. RPTVs are available in cathode ray tube (CRT), LCD screen (LCD), digital light processing (DLP) and liquid crystal on silicon (LCoS). These are just some of the variations. RPTVs are often preferred, because even with larger screen sizes, the cost does not vary much. This is not the same if one were to invest in digital LCD screens or plasma.
There are two basic RPTV screens.
CRT display RPTVs range in size from 42 to 82 inches. They are unbeatable in terms of projection quality. However, they need spacious rooms for installation, as they tend to be bulky. They also require periodic adjustments because the pipes need to stay aligned to get the most out of them.
The other form of RPTVs is the microdisplay TV, this works with fixed pixel based technology. The colors are lighter and remain constant. Every screen point on the screen is equally bright and clean. The advantage of these screens is that they do not require any periodic tinkering. The only time this TV requires a great service is when the lamp used on the inside dies.
High Definition TV
These can be tables or wall-mounted devices and are available as plasma or LCD screens. LCD screens are relatively slimmer and much lighter. They range from about 23 to 60 inches with a width of no more than 5 inches in any size. They have a resolution of 1,080 pixels and have images that are cleaner than plasma. This type of screen is best suited for bright rooms for the brightness that the image radiates. The only downside is that you can not view the screen from all angles. Plasma TVs are suitable for those who love large TVs. The smallest is 42 inches. They consume less energy than LCD screens. But when it comes to image, clarity is never a problem except for the rare occasions when the corners tend to burn a bit.
