A plasma screen is a technology recently developed for the purpose of offering high-quality television on large-screen equipment, starting at 37 inches. Its system consists of multiple and tiny cells that are located between two glass panels composed of a mixture of gases. This gas, a product of electricity, is converted into plasma which, 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 of a 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 their quality conditions and their speed of response, plasma screens were more suitable than LCD screens as an HDTV or high definition vision 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 to manufacture, which makes them cheaper to purchase, and consume up to 30% less than their plasma competitors. Additionally, a plasma screen can suffer from a "screen burn" effect which, as a result of being on for a long time, causes the image to remain fixed or as a watermark on the screen. On the other hand, the LCD monitor can produce brighter, more saturated and purer colors than plasma. Finally, plasmas do not usually have a long useful life and depend to a large extent on the conditions in which they are used.
