LCD Plasma TV Sounds Incorrect
The increasing quantum of technological advancements in the field of home entertainment has left people in a real quandary about the terms that are floating around. You hear that cathode ray tube technology has given way to plasma technology and then you hear about Liquid Crystal Display technology: well the list is endless. This also leads to confusion about the prevailing terms. Therefore if you hear a person mention a LCD Plasma TV, it means he is totally confused about the latest in television technology. The question that he will probably ask you is what the term should be. To put things absolutely straight, there is no television that is called LCD Plasma TV. It should be either an LCD TV or a Plasma TV, it just cannot be both. The confusion is mainly because televisions that adopt both these technologies look alike. Today very few people have a television set that is shaped like a box. In days gone by this was the most commonly found kind of television that was found in all homes. The only variation that you could have spotted would be regarding the size of the televisions. Either you would have a television with a screen that measured 20" or one as small as 6". Giant television screens were also available; all these adopted the cathode ray tube technology.
If you really want to understand why there is no such a thing as a LCD Plasma TV, you need to understand what each of the technologies really is. First let us begin with the LCD technology. This involves a process wherein current is passed through liquid crystals which are part of a coating on one of the layers of see-through material. There are two of this kind of see-through or transparent material, one of which is coated with the liquid crystals. Since these crystals do not have the capacity to produce their own light, a light from outside needs to be directed to them. This will ensure that the crystals light up and create an image which you can see as the moving images on the screen. It is not enough if you understand how an LCD works. In order not to make the same mistake of saying LCD Plasma TV, you also need to know the basics of plasma technology. Here there are phosphors that actually light up because of the plasma that is present between two glasses. There is a neon-xenon gas that is put in between two very thin glasses in a plasma form. When the gas gets charged, the various phosphors start lighting up in quick succession; this in turn results in images on the screen. A person uninterested in knowing how a television really works will not worry about making a mistake in the terminology that he has used, namely, LCD Plasma TV. He will want to know if one technology is better than the other. |
