The invention of flat screen TV is a breakthrough in the manufacture of television. There are two main types. The first is known as the TV plasma that works with continuous loading and unloading of cells containing gas. Second type is known as the LCD (LCD), which produces the image where the fluorescent light falling on the LCD. Both technologies have their advantages and disadvantages.
Plasma TV has important advantages. He has a brilliant image quality, as can show the deep black color with great precision. This helps to produce images with a contrast very well, improving their quality. This property is very important, while to view the video particularly dark scenes. For LCD backlight is used to fall on compact layout of cells to produce the image, therefore lighter black color occurs in it.
Point angle of view is also very important to consider. The image on a plasma TV can be seen clearly at an angle of 160 degrees. In another type of flat screen televisions, the image is clear only from the front. Plasma TV in brighter colors occur due to the fact that the amount of electricity passing through the cells can be changed in a split second, to that effect. In LCD TVs, there are relatively bright colors.
Plasma TVs are sensitive to temperature and their performance varies with an increase or decrease of temperature. For this reason, do not function well the highest elevations, where the temperature is lower. This disadvantage due to the use of gas properties change dramatically with temperature variations. LCD TVs generally do not face to this problem and are ideal for use in high altitude. Plasma TV is usually heavier than LCD TV and is more difficult to install. Heavier size makes it difficult move from one place to another.
Plasma TV is available in screen sizes ranging from 32 "to 100". LCD TV screen size above 37 "generally not found, because the transistors show very poor Above this screen size. LCD TV durable compared to plasma TVs. It was a life of 60,000 hours. Plasma TVs even shorter shelf life and can last for hours 30000-60000.
LCD TV consumes 30% less energy compared with plasma TV. This makes an economical product. A high energy plasma TV due to the fact that a large amount of electricity used in the loading and unloading of the cell to produce the image.
