Until recently, people were stuck with large, clunky CRT (cathode ray tube) devices in their daily lives, in the span of a decade after they hit television screens. LCD (liquid crystal displays) and plasma displays have made CRT displays obsolete. In this article, I'll explain in detail how the basic physics of LCD and plasma technology work, compare the two, and decide which one is best for your needs. The wide range of applications for which LCD displays are used is impressive; they include computer monitors, televisions, dashboards and road signs. Many consumer devices such as video players, gaming devices, clocks, watches, calculators and mobile phones have benefited from the unique characteristics of LCD displays. They are available in a wider range of screen sizes than CRT and plasma displays and are by far the most popular display technology. Plasma displays have some advantages over LCD displays. Modern color LCD displays work on a similar principle to monochrome LCD, the main difference is in the pixel configuration and light source. A pixel on an LCD screen is made up of 3 sub-pixels, each of which is a primary color, but each sub-pixel is activated by current passing through an electrode and changing the properties of the liquid crystal. This type of LCD screen is made up of 7 layers, the first of which is a fluorescent backlight different from the mirror of the basic LCD, this allows the screen to appear bright and to be clearly seen in a dark room. The screen consists of a mirror then a layer of polarized film, a layer of liquid crystal sandwiched between a positive and negative electrode/glass, another layer of polarized film placed perpendicular to the 'another piece of ...... middle of paper. .....vibrant colors. Some high-end LCD displays can have refresh rates and viewing angles similar to plasma displays while still retaining all the benefits of LCD. Finally, plasma displays are less energy efficient and could overheat if not placed in a well-ventilated area. I think a good quality LCD screen would be the best choice for your home theater because the theater will be in an enclosed space so there will be no overheating. problems. You'll avoid issues like burn-in and shortened lifespan which are issues that have plagued plasma displays. Plus, by purchasing a high-end LCD TV, you'll avoid all the problems that plagued earlier LCDs, like slow refresh rates. If you buy a good LCD screen, it should provide the best overall experience because you will avoid the problems of plasma screens while minimizing the problems of LCD screens..
