If you've ever wondered how a plasma screen TV works, then you've come to the right place. In this article we will look at plasma technology in order to understand why a plasma television has a big advantage over other TV technologies.
Despite the fact that there are a number of other types of TV available, the plasma TV is showing no signs of losing ground to it's cheaper rivals such as LED and LCD TVs.
What is the reason for this? It is because the picture quality of a plasma TV is still acknowledged to be superior to that of its rivals.
The quality of the image has always been the strong point of the plasma television, and in this area the other types of TV have always come up short.
So let us take a look at how a plasma screen TV works so that we can understand the secret of its success.
A plasma screen TV is similar to an LCD TV in that it is a type of flat screen TV, and the screen is made from a large grid of small pixels - but that is where the similarity ends.
The pixels in a plasma TV are filled with a gas, and these pixels are positioned between two electrodes. Keeping all this together are two glass plates at either side. Each pixel is also coated with a phosphor material and it is this phosphor that interacts with the gas particles to create colour.
The two electrodes at either side of the pixel are charged with a voltage and this causes an electric current to flow through the pixel cell - and therefore through the gas. This current stimulates the gas atoms and causes them to release ultraviolet photons.
The photons that are created then interact with the phosphor coating on the walls of the cell to create light which can be seen by the human eye, and it is this colour which makes the image we see on our screen.
In actual fact, each individual pixel in a plasma screen is divided into three smaller pixels, each with a phosphor that creates red, green or blue light. As you are probably aware, by mixing red, green and blue in different amounts we can create all the colours in the spectrum. Therefore, each pixel can be accurately set to the exact colour required for the picture as a whole by varying the level of electrical charge in each pixel. By doing this across all the pixel cells in the plasma screen, it is possible to create an image with an excellent picture quality and colour accuracy.
It is the fact that each pixel is individually lit throughout the plasma screen which makes a plasma TV picture stand out from the other technologies such as LED and LCD TVs.
So as we can see, it is down to the way a plasma screen TV works that enables it to produce such a great picture. LED or LCD TV technology is still trying to match the quality of the image we get from a plasma, and they struggle to compete because of the limitations of their backlighting.
However, there are other important things to understand before you go out and buy a plasma TV, such as the right size, resolution and connection types. To understand everything you need to know to make the right buying decision, follow the links below and get further information.
