Buying a new TV can turn out to be quite frustrating if you have no idea what you are looking for. From plasma to tubes – there are more different types of TV devices than covers of magazines. Before you start thinking about the differences between digital, HDTV, SDTV and EDTV take a look at what the modern consumer’s market can offer. Here are some of the most important types of TV devices:
1. Tube or Direct View
A tube TV is also called direct view and it is the closest to what baby boomers had to watch back when they were kids. This kind of device is a cathode ray tube (a specialized vacuum tube). The most important thing about CRTs is that they come in different sizes and shapes up to about forty inches. The picture they create is good from every single angle and they are a lot cheaper than the rest of the other options on the market. They might be a bit heavy and bulky in build but they are surely long-lasting and their lifespan can be decades.
2. Digital Light Processing or DLP
DLP was first made in 1987 in Texas. The name comes from the ability of these TV devices to process light with help from optical semiconductors referred to as DMD chips (Digital Micromirror Device). This small chip has more than a million mirrors! Each one of these mirrors’ size is about 1/5 of the thickness of human hair. At the moment, there are only fifty manufacturers that produce this kind of devices. DLP’s come in front and rear projection. These are not susceptible to burning in, but there is the common Rainbow Effect some people have noticed.
3. Liquid Crystal Display
When it comes to LCD, there are millions of choices on the market regardless of whether it is rear projection or a flat panel. Liquid Crystal Display TVs are popular with their flat panels because they are quite thin and lightweight. This is very convenient for the folks who want to use their TV set as a monitor for their PC as well as a TV. An LCD is not at all susceptible to burn-in. Some LCDs that have slower responding times sometimes show a ghosting effect and some others have a screen door effect. Therefore, it is quite important to inspect the LCD screen of all the TV devices you are considering before you pick one.
4. PDP or Plasma Display Panels
This is the type of TV devices that can be called high-end electronics. This is so because we usually get told that plasma will provide us with the best possible picture we can get for our money. All plasma TV sets have flat panels. Most of them have a size of 40 to 49 inches. Their prices compete with the prices of LCD TVs, but the picture is stunning and puts you right in the middle of the action. This is why plasma TV devices are considered the best up to date.
