New innovations have radically changed the way people around the world perceive the concept of entertainment. Be it cinema or music system, mp3 players or television, people are constantly adopting new ways of entertainment, jettisoning the old ones. Technology changes always. You can`t stop the advancement in technology. There is some advancement in terms of technology in everyday things like cell phones, calculators, computer monitors, and televisions, too.
The latest version of television is Liquid Crystal Display Television or LCD TV. Old model tube (CRT) TVs are large and bulky. They need a lot of space for placing it. During the early 2000`s LCD flat panels started ruling over the television market from the typical CRTs.
LCD TV is a flat screen television which needs less space for placing. They are slim, lighter, and hardly goes beyond 3.5 inch in thickness. They have a very trendy look which draws attention of others. The technology has penetrated our everyday lives. But how does it work? Basically, a very large amount of tiny liquid crystals are held between two electrodes. When a charge is passed between the tiny liquid crystals they react to the change. This reaction emits light which creates an image that we can viewed on the screen of the television.
Usually LCD TVs are cheaper as compared to Plasma models. However, when it comes to large screen size, plasma TV is sold for better prices. If you compare with the CRT tube TVs, then the price is a little higher, no matter the screen size.
The screen lifespan of Plasma and LCD TVs should not be an important way to differentiate them. Plasma TV have a reported half life of 30,000 to 60,000 hours. While the average tube (CRT) TV set has a half life of around 25,000 hours. LCD TV can be installed on your own where as you have to depend on an expert to install a plasma TV. The best part of LCD TV is that it draws only about 60 of the power consumed by plasma displays. You are also protected from harmful electromagnetic waves while using it.
LCD TVs have certain minor drawbacks too, with restricted viewing angle and limited contrast ratio. They have graying effects on the screen which deteriorates the clarity of the image, mainly the color factor. The viewing angle of an LCD TV is up to 160 degrees, where as the viewing angle of plasma TV is up to 170 degrees.
The right LCD TV screen placement is a very important point to consider. Sitting the right distance from your TV set optimizes your viewing experience. Also for the viewing height, your eyes should level with the middle of the screen, since the LCD image picture will look its brightest as this level.
LCD TVs may often look better in `real world` situations, as they reflect very little light, enabling them to keep levels in well lit rooms. This way, LCD TVs will usually meet the brightness expectations of most customers.
Technology has brought many interesting products in recent years. One of them was the LCD TV. For those who love indoor entertainment, like watching TV, look no further. LCD TV will provide one of the best viewing experiences.
