Today, the question of which is better is not a CRT monitor or LCD display. For the average user, the choice is obvious. The technology for the production of LCD screens is constantly being improved and opens up new horizons in this area. What prospects are possible with its further development? Can LCD successfully compete with alternative technologies?
The abbreviation LCD
(Liquid Crystal Display) itself means the well-known liquid crystal display. This technology was invented a long time ago, but due to 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 conquered almost the entire market.
The development of LCD technology has been going on for almost 30 years and has led to amazing results. To date, the LCD-display has almost completely replaced its electronic competitor from store shelves. It has excellent performance and successfully competes with alternative devices.
The modern LCD-display in its parameters has far gone from its black and white predecessor:
- He began to serve much longer.
- The screen resolution and its size have improved many times.
- The brightness is not inferior to a CRT monitor.
- Good contrast (250: 1).
- Excellent viewing angle (120 degrees).
- Small dimensions and light weight.
Today, an LCD display is more attractive to a customer than a CRT monitor. An alternative to it can only be a plasma screen, but before its practical implementation, which will satisfy the needs of a wide range of users, a long time will pass. The technology of its production itself is too expensive and time-consuming, it has high energy consumption, and its color rendering problems are the same as those of other competitors. In addition, it is very difficult to achieve high resolution on a “plasma”. Its main advantage is the high brightness and contrast of the image.
By this parameter, it overtakes the other
types of monitors. But LCD displays are leaders in their dimensions; they are much more compact both in 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 each production has its own shortcomings that cannot be eliminated. 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 of them on one screen. To distinguish them from the rest is quite simple - such pixels always glow in only one color. Test the screen by changing the same type of pictures, and select the highest quality.
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 area. The luminosity of such screens is constantly growing and today has reached the level of modern LEDs.
