Seeing the World in High Definition with Flat Screen HDTVs
Years ago, the
only high definition televisions (HDTV) were bulky rear projection
sets which have parts that generally break after only a year or two
and are literally hundreds of pounds, making them difficult and at
times nearly impossible to move. 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 to decades past, but new plasma and
liquid crystal display (LCD) televisions were sleek and futuristic
in appearance. Flat screen HDTVs look much nicer, weigh less, and
use a fraction of the energy of older televisions, but there are
several differences you should be aware of before making a
purchasing decision.
Plasma and LCD
Plasma and LCD flat screen HDTVs 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 HDTVs 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 HDTVs 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 HDTVs 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 HDTVs 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. If you are looking to watch high
definition content, look no further than flat screen HDTVs.
