Alternative technologies: LCD-display or "plasma"?

Today, there is no longer a question of what is best - a CRT monitor or LCD-display. For the average user, the choice is obvious. The technology of production of liquid crystal screens is constantly being improved and opens new horizons in this field. What prospects are possible with its further development? Will LCD successfully compete with alternative technologies?

The very abbreviation LCD (Liquid Crystal Display) means a well-known liquid crystal display. This technology was invented a long time ago, but due to the difficulties in industrial production, it was not widely used. Small screens on such crystals could be seen on the electronic clock of that time. They were black and white and did not last long. At the same time, new and high-quality models of cathode-ray tubes (CRTs) appeared, which gradually gained almost the entire market.

The development of LCD technology has been going on for almost 30 years and has led to striking results. To date, LCD-display almost completely replaced its electronic competitor from the stores. It has excellent performance characteristics and successfully competes with alternative devices.

The modern LCD-display in its parameters has far gone from its black and white predecessor:

1. He began to serve much longer.
2. The screen resolution and its size have improved many times.
3. The brightness is not inferior to a CRT monitor.
4. Good contrast (250: 1).
5. Excellent viewing angle (120 degrees).
6. Small size and light weight.

To date, the LCD-display is more attractive to the buyer than the CRT monitor. An alternative to it can be only a plasma screen, but before its practical implementation, which will satisfy the needs of a wide range of users, it will take a long time. The very technology of its production is too expensive and time consuming, it has a high energy consumption, and the problems with the color rendition are the same as those of the other competitors. In addition, it is very difficult to achieve high resolution on the "plasma". Its main advantage is high brightness and contrast of the image. By this parameter, it overtakes other types of monitors. But in terms of their dimensions, LCD-displays are leaders, they are much more compact and "plasma", and CRT. It should also be noted and their complete safety for human health. They do not create harmful radiation and electromagnetic fields.

But in every industry there are drawbacks, which can not be got rid of. Before you buy an LCD-display, pay attention to the presence of "broken" pixels. It is believed that there should not be more than three on one screen. To distinguish them from the rest is quite simple - these pixels always shine with only one color. Test the screen by changing the same pictures, and choose the best one.

Interesting prospects are the technology of light emitting plastics (Light Emission Plastics). It is constantly evolving, and Cambridge Display Technology has made considerable progress in this direction. The luminosity of such screens constantly grew and today has reached the level of modern LEDs.
