To give a full answer to the question what is an LCD Full HD TV there are a couple of points must be answered.
What is and LCD TV?
LCD or liquid crystal display televisions are TVs that utilize LCD technology to produce the images that we see on the screen. Very simply put a liquid crystal display uses a layer of liquid crystal pixels sandwiched between layers of glass. For the display to produce different colors each individual pixel is divided into three sub pixels for the primary colors (red, green, blue). The result is a thin panel which has a matrix of many thousands of pixels.
The LCD panel on its own does not produce any light. The images created by the panel must be illuminated by a light source. This has typically been done by the use of a fluorescent light which is deflected from behind the LCD panel. Once the light is passed through the panel the images become visible.
The resolution of a Full HD LCD TV is defined by the number pixels that makes up the panel. The pixels are arranged in horizontal lines and typically a HD TV will have either 720 or 1080 lines. The higher the number of pixels the higher the resolution and hence the greater level of detail the television is capable of producing.
What is Full HD TV?
Now we now the what an LCD TV is, what is Full HD? Full HD is popular term used to describe televisions that conform to the 1080p standard. This means firstly they have 1080 lines of pixels.
Secondly they also use progressive scanning. Scanning is the method by which the images are refreshed or redrawn on the screen. As we know the images are produced by the rows of LCD pixels, the rows of pixels are refreshed many times a second and as the images on-screen change the rows of pixels are redrawn. With progressive scanning every row is refreshed for every frame of the picture (the other option is interlaced scanning where only alternate rows of pixels are refreshed for every frame). The effect is that progressive scanning produces smoother pictures than interlaced.
Summary
So when you put both together you get the answer an LCD Full HD TV is a television that uses LCD technology and the 1080p standard with progressive scanning.
