Developers of plasma technologies have made significant progress in working on high-contrast images. For example, Panasonic claims that their plasma panels achieve a contrast ratio of 3000: 1. This technology blocks the supply of energy to specific pixels to form black or dark dots. Thanks to this method of operation, plasma technology does form black dark colors. But what is plasma?
Fully or partially ionized gas today has a well-known name - plasma. A TV with this technology has many advantages. But about them a little later. The density of negative and positive charges in this gas is almost the same. In the process of combustion and explosions, in laboratory conditions, the formation of plasma occurs in a gas with electric discharge. What plasma is, people learned back in 1929, when the famous American scientists - Tonsom and Langmuir introduced this concept into physics. At that time, this phenomenon was represented by a substance heated to millions of degrees. At such high temperatures, the atoms collided with each other with incredible strength, while they simply could not remain intact. Upon impact, the particles were divided into components - atomic electrons and nuclei. Electrons were endowed with negative charges, and nuclei were positive.
Today, for people who want to choose a TV for themselves, the question arises - what is better: plasma or LCD? No one can give a definite answer to this question. What is plasma, few know, but not everyone understands LCD TVs. In stores, they advise what is beneficial primarily to them, sellers. In this case, it is better to contact specialists, they will be able to explain everything to you in an accessible way.
Pros and cons of the models provided.
Plasma technology in televisions is characterized by the following qualities:
density is the number of free electrons per mass per unit volume;
the degree of ionization is the ratio of the number of ionized particles to their total number;
quasineutrality. Plasma is a fairly good conductor, and this property is very important. Due to this quality, the plasma shields all electric fields.
The benefits
Plasma TVs are:
small thickness flat screen;
stylish and original design;
large screen sizes;
completely no flicker;
plasma TVs do not create harmful magnetic and electric fields, since they do not have a source of high-voltage anode voltage and a scan device;
the screen does not attract dust to its surface;
lack of x-rays;
Plasma TVs have no problems of mixing, focus and linearity;
viewing angle of about 160 degrees;
plasma displays the same resolution as on the input channel;
the service life of such TVs is about seventeen years.
After people learned what plasma is, enterprises for its processing began to develop at an incredible speed. Today it is a widely used technology that is used in many areas.
