Let's see how the LCD differs from the "plasma"

Very often, from people choosing a new TV, you can hear the question of what LCD is different from "plasma". Many people confuse these concepts and do not see the difference between them. In this article, we'll figure out what LCD is different from "plasma", what are the advantages and disadvantages of both technologies.

Plasma TVs for a long time were the leaders in sales. They have a thin body and a wide screen. However, to date, LCD technology has successfully competed with LCD technology. A few years ago, LCD matrices were used only in the production of computer monitors. Modern LCD monitors have grown significantly in size, they even by some parameters were able to circumvent the plasma panels. To date, LCD TVs and "plasma" are very widely represented in household appliances stores. The buyer has plenty to choose from; Even 20 years ago it was difficult to imagine such a huge assortment, differing in design, size and characteristics.

Now let's look at the parameters of both technologies to understand what LCD is different from "plasma". The first indicator, which is essentially shared by these devices, is the amount of electricity consumed. A working plasma TV consumes three times as much energy as an LCD device of the same size. This is due to the technologies for creating images on the plasma screen in which one cell consumes 200 to 300 volts. In contrast, one cell of the LCD TV consumes only 5-12 volts. The spread of electric current consumption in plasma devices is explained by the brightness of the glow of the pixel at a given moment. If the picture is light, then the maximum electricity consumption, and if in dark colors, then the consumption is minimal. In LCD monitors, the current consumption does not depend on the image transmitted on the screen. Power of pixels in the calculation is not even taken into account. The main consumption of electricity in such a TV is spent on the backlight, which is located behind the LCD panel.

For many people, the low consumption of electric current is a priority, therefore, having started reading about what distinguishes an LCD TV from "plasma", and having learned about the first such parameter, they can immediately make a choice. We continue to consider the differences between the two technologies.

So, the second parameter is the need to cool the plasma device (often they have built-in fans). The sound of working coolers is very annoying when you use the "plasma" at home. LCD TVs do not need cooling.

The third important parameter in our comparison is the resolution of the monitor. Plasma technology is characterized by a large distance between the pixels. For LCD TVs, this distance is much smaller, so the image is much clearer. So, plasma screens with a diagonal of 42 inches have a resolution of 860x420 pixels. LCD TV with a diagonal of only 40 inches has 1280x768 pixels.

The fourth parameter of comparison of these technologies is the contrast of the image. At this stage, plasma TVs have considerably bypassed their competitors. Thus, LCD monitors have an average contrast ratio of 500: 1, while plasma displays have a contrast ratio of 4000: 1 and even more.

The next important characteristic is the viewing angle, and here the plasma technology is also ahead. The LCD TV has a maximum angle of 170 degrees, but already significantly reduces the contrast. In plasma monitors, the viewing angle is practically unlimited.

Even in LCD technology, the weak spot is considered black - it is not as saturated as a plasma TV.

The last parameter in our list will be the aging of the screen. In plasma monitors, this process is more noticeable. In addition, they are very capricious with respect to operating conditions. LCD technology is more stable and will last longer.

So we looked at how the LCD differs from the "plasma", but you have to choose yourself.
