LCD or Liquid Crystal Display initially intended for laptops has gained wide acceptance in digital clocks, microwave ovens and CD players and other electronic devices. Before discussing the advantages of LCDs, it is important to understand how the technology works. The LCDs trap a liquid crystal solution between two panes of polarized glass. An electric current passed through the liquid causes the crystals to align in such a manner that light is either allowed to pass or is blocked. Based on the wavelength of the light and where it is passed, the LCD monitor displays the images.
The salient features of the LCD technology include brighter, clearer, and sharper images obtained at a click of a mouse. Features such as a high picture resolution, color, clarity and brightness coupled with improved visibility of smaller fonts and a reduction in response time have all contributed towards increasing the market demand for LCD monitors by industrial enterprises ranging from banking, ATMs, games to hospitals and restaurants.
The dynamics of constant research has resulted in many advances in this technology. Initially incepted for a screen of about 12 to 14 inches, LCD is now a popular choice for a 50-inch screen. Another benefit of the advancement of technology is that the manufacturers have been able to cut down on the cost of production. This in turn, has brought down the cost of LCDs thereby making it a feasible choice for various industrial enterprises. Also, the LCD has a long life of about two decades allowing a person to use it between 8 to 10 hours daily.
The advantages of LCD monitors are such that they are gradually replacing CRT or the cathode ray tube monitors. This is because LCD technology is better for the eyes. LCDs have uniform screen brightness. Also, the screens covered with a flexible surface are less susceptible to glare as compared to the CRT screen.
Given the advantages of LCD, it is not surprising that LCD monitors are slowly and steadily replacing the conventional computer systems that used CRT technology for the computer display.
