1.0 How Does an LCD HDTV Work?
Much like plasma has a gas that is excited by electricity, which morphs it into quasi-solid plasma between two sheets of glass, an LCD HDTV liquid crystals stored in between two sheets of polarized glass. These crystals get "twisted" or "untwisted" to make the full range of light to dark. The in-between areas are where an LCD creates grayscale. A fluorescent light is used to create color, starting with the whitest of whites and, as the crystals are untwisted, they can create millions of different colors between the fully twisted and fully untwisted elements. This can result is as many as 16-plus million colors that can be reproduced by a modern 1080p LCD HDTV.
2.0 Which HDTV is Better: Plasma or LCD?
The term "plasma" has become the generic term for a flat HDTV, despite the fact that there are two major technologies driving the flat HDTV market today, with others, such as OLED, being developed for future technologies.
Plasma HDTVs are thought by video calibrators to have the best "blacks" as promoted by plasma supporter with their line of KURO sets (KURO means black in Japanese). In a darker room, the blacker blacks allow for more contrast, which creates a more three-dimensional-looking HDTV image.
LCD HDTVs are generally sold for environments that might have more ambient light in the room, as they tend to be able to make a brighter picture than other HDTV technologies.
To date, both formats have been honed to a point where they make a fine HDTV image. Most people pick one in the biggest size they can afford. If you pick a premium brand, get it professionally calibrated and hook up a Blu-ray player for a 1080p video source - you can't lose.
3.0 All About Refresh Rate
An LCD HDTV's refresh rate is the number of times a display's image is refreshed per second. The refresh rate is almost uniformly measured in Hertz. A refresh rate of 75 means the image is redrawn 75 times per second.
Scientists who study the eye say the tipping point for the refresh rate is about 70 Hertz. However, most of today's LCD HDTVs have refresh rates of over 120 Hz. The effect of 120 Hertz refresh rates includes a TV that looks smoother and less blurry, even during complicated movement scenes in movies and/or other fast-moving images.
Sony recently showed 240 Hertz refresh rates on their LCDs.
