Definition of Plasma (technology)

A plasma screen is a technology recently developed for the purpose of offering high-quality television quality on large screen computers, starting at 37 inches. Its system consists of multiple and tiny cells that are located between two glass panels made up of a mixture of gases. This gas, a product of electricity, it becomes plasma that, in turn, emits light.

These types of displays are bright, display a wide color gamut, and can be manufactured in sizes up to more than 260 cm. diagonal. Due to their quality and resolution, they are ideal for watching movies, resembling the experience that you live in a room movie theater.

The first plasma screen was created in 1964 by a group of students from the University of Illinois in the United States. Not until long ago there was a tendency to consider that due to its quality conditions and its speed In response, plasma displays were more convenient than LCD displays as HDTV or high definition viewing technology. However, improvements in LCD technology have made it its great competitor in the market for displays of 40 inches or more.

Regarding the advantages that a plasma screen has over an LCD screen, it can be said that the former has a higher contrast and viewing angle. In turn, the response time is shorter and exhibits a greater number of colors and resolution. In addition, plasma does not contain mercury among its components and is gentler on the human eye.
However, LCD screens have a lower cost of manufacturing, which makes them cheaper to acquire, and consume up to 30% less than their competitors in plasma. Furthermore, a plasma display can suffer from the "screen burn" effect which, as a result of remaining on for a long time, causes the image to be fixed or as a watermark in screen. On the other hand, the monitor LCD can produce brighter, more saturated and purer colors than plasma. Finally, plasmas do not usually have a long useful life and depend largely on the conditions in which they are used.
