Sometimes where high tech meets the average consumer communicating is often like speaking two separate languages. You might a 46 inch LCD HDTV 720p flat screen you absolutely love but have no idea why it's $400 dollars cheaper than the same brand 46 inch LCD HDTV 1080p right next to it. To you the TV's are the same size but if you checked the picture out you would see the difference. So lets give a brief synopsis on the key terms when you shop for your next flat screen.
LCD
Liquid Crystal Display: A display method created back in the 1960s where the orientation of rod shaped molecules (like a liquid) bend light like a crystal would. So if you vary the orientation of these filters it will determine how the light you ultimately see passes through the crystals. LCD are not new but the technology is still out there and in use today. You can also find LCD screens used for computers monitors. They provide a very clean image and is what most flat screen TVs are made with today.
HDTV
High Definition Television: The highest form of digital TV you can receive. You can think of it as if you were watching a movie at the movie theater with its 16:9 aspect ratio. Also along with HDTV is the resolution you can have, 720p, 1080i and 1080p. To give you a starting reference, traditional TV sets had a 480 lines. The lines determine how good of a resolution you are going to have. We also have the "i" and "p" which follow the number of lines used to create an image. These stand for "interlaced" and "progressive". Just remember that the progressive scan is the more desirable as it processes the image twice as fast as the interlaced scan. What this will do for you is create a better clarity and and color on your final picture. Also keep in mind that these scans are considered more important on flat screens larger than 32 inches. So when you purchase a 46 inch LCD HDTV 1080p you want to keep this in mind.
