Years ago, the only high definition televisions (HDTV) were bulky rear projection sets which had finicky or unreliable parts that were as likely to break after only a year than work flawlessly. They also cost an arm and a leg, making it difficult to justify as anything but an indulgence for those with plenty of disposable income.

A few years ago, two new technologies were introduced that would forever change how we all watch high definition content. Old rear projection televisions looked like they belonged in the distant past compared to the new plasma and liquid crystal display (LCD) televisions that had a  sleek and futuristic appearance.

 

Furthermore flat screen hdtv televisions weigh less and use a fraction of the energy of the older style televisions, but there are several differences you should be aware of before making a purchasing decision.

 

Plasma and LCD

 

Plasma and LCD flat screen hdtv televisions are fairly different from one another, although they can both display the highest resolution high definition content today or 1080p video. They are both very slim comparatively to rear projection televisions, and use less power. However, for image quality, video enthusiasts tend to like plasma flat screen hdtv televisions more because of their higher contrast ratio (how many different shades of a color which can be displayed so that colors can be deeper or lighter). Most people claim that plasma screens can get deeper blacks, which improve the overall image quality of the whole picture.

 

LCD flat screen hdtv televisions in recent years have nearly reached the contrast ratio of plasma screens though, and they are generally much cheaper than plasma televisions as well. In years past, LCD screens were not as large as plasma screens, but this has also changed in recent years so that LCD flat screen hdtv televisions can reach sizes or 60” (five feet diagonally) or even larger. Also, both technologies have matured, and as with all other technologies (computers, for example), LCDs and plasma screens have dramatically fallen in price to the point where they are a fraction of what they used to cost.

 

However, some new exciting technologies are about to be released which are set to beat plasma and LCD flat screen hdtv televisions in terms of power usage and image quality. The most talked about one is the organic light-emitting diode (OLED). Not only will they draw significantly less power and produce better visuals, but they can also be used with many different materials, and they are expected to be significantly cheaper to produce, resulting in greater affordability for the consumer.

 

There is far more high definition content available to watch these days. Apart from DVDs, many terrestrial and satellite TV stations are broadcasting in HD. There is a gentle push on consumers to update their televisions by extolling the virtues of HD broadcasting thus it is only a matter of time before most people will have some kind of technology that allows them to view HD quality content.  If you are looking to watch high definition content, look no further than flat screen hdtv televisions.
