It's worth the time to quickly understand the nature of these ingenious tools of electronics to better determine which method of technology you prefer or is more adapt to your location of use for these types of televisions. Let's quickly reference their origin of discovery and how they work.
LCD and the History of it's Discovery LCDs are everywhere we look, but it didn't happen overnight. There was a long time from the discovery of liquid crystals to the vast applications of LCD we now enjoy. Liquid crystals were first discovered in 1888, by Austrian botanist Friedrich Reinitzer. Reinitzer observed that when he melted a curious cholesterol-like substance (cholesteryl benzoate), it first became a cloudy liquid and then cleared up as its temperature rose. Upon cooling, the liquid turned blue before finally crystallizing. Eighty years passed before RCA made the first experimental LCD in 1968. Since then, LCD manufacturers have steadily developed ingenious variations and improvements on the technology, taking the LCD to amazing levels of technical complexity. And there is every indication that we will continue to enjoy new LCD developments in the future!
Plasma TV Display In a plasma TV display the electrical current running through it causes negatively charged particles to rush toward the positively charged area of the plasma or color spectrum, and positively charged particles are rushing toward the negatively charged area. This causes a collision of sorts and results in a luminous or florescent type of reflection of light which greatly enhances the color spectrum of light resulting in a clearer more defined display on the screen.
HDTV stands simply for High Definition Television. It is a broadcasting standard for sending television signals in digital format instead of the more traditional standard or analog method. HDTV is a vastly improved method of displaying more lines of information compared to an analog type of display of information lines. Where an analog processor can only display 500 lines of information, HDTV can process some 1800 lines of information and results in a much more refined and greater resolution display.
Now that you understand a little more about the current age of television monitoring, you can better choose your next television set. Keep in mind that as the technology improves, initially so does the price go up, but if you can be patient with your current model until the initial run on the 'new technology' subsides and the prices readjust for market share and affordability.
