Great Combination - LCD And HDTV
The easiest and simplest way to describe what LCD HDTV is is to break it down in two parts, HDTV and LCD.
HDTV
HDTV stands for High Definition Television. High Definition usually refers to 720 vertical lines of resolution. It has much greater resolution than analog televisions.
When people upgrade from analog to digital they most often comment on the absence of fog or snow in the picture. HDTVs all operate by receiving high definition signals. You may receive your HDTV Signal "through the air" by using a device called an antenna.
Another way you might receive the HDTV signal is with an HD tuner. Most new HDTV sets have an HD tuner built in. If you own an HDTV without an HD tuner built in, then you will need an HD tuner box, which can be rented or purchased from your local cable or satellite company.
LCD
LCD stands for Liquid Crystal Display. An LCD is a flat, thin device that is made up of a number of pixels arrayed in front of a light source or reflector. It is often used in small electronic devices like games, because it uses very small amounts of electric power.
LCD HDTV Technology
LCD HDTV technology is used by televisions to produce an image. Computers also use LCD screens. During the early 1900s, almost all computer monitors were manufactured with LCD flat panels. The biggest reason for this was that energy consumption was much less when compared to the old CRTs.
In the early years of LCD televisions, there were major problems with visual display. One problem was that anytime there was fast action on the screen, there was a "ghosting" effect on the screen. A second problem was the viewer almost had to stand directly in front of the screen, because light the emitted by the TV focused directly ahead.
These problems have been solved and LCDs - especially LCD HDTVs -- are now popular all over the world .
Competition From Plasma TVs
LCD's biggest competition comes from plasma and rear-projection. A few years ago it was commonly believed that LCD HDTV technology was primarily suited for flat panel televisions that were 40 inches or smaller, because Plasma had the edge in performance and cost. This is no longer true.
Manufactures can, and do, decrease the weight, increase the resolution, and lower the price. The major manufacturers of both computer monitors and televisions are expected to invest billions of dollars in LCD and HDTV technology in the coming years.
What a great combination, LCD and HDTV.
