LCD Televisions - Advantages and Disadvantages

LCD televisions are television sets that use LCD technology, just like in the computer LCD monitors, tuned up for video and television display. Many features of LCD Television rendered it more practical than CRT TVs and thus LCD TVs began to gain instant popularity among the consumers.

LCD televisions are referred to as "transmissive display", because light is not emitted by the liquid crystals themselves. A light source behind the panels emits light that gets redirected by a white panel to the rear of LCD, which distributes the light evenly to generate uniform image. This is the basic principle behind the working of LCD televisions.

The LCD tv display has a liquid crystal solution sandwiched between two polarizing transparent crystals. In order to form a template for the liquid crystal, the front layer glass of the display is etched on the inside in a grid pattern. These crystals bend light in response to an electric current and each crystal behaves like a shutter either allowing light to pass through or blocking it. So a pattern of dark and transparent crystal are formed that generates the image.

LCD televisions have their own set of advantages and disadvantages. The LCD TVs do not have a rapid pixel response time and thus in cases of fast moving objects exhibit motion lag. Improvements have been made to overcome this defect, however this works only if your screen size is lesser than 35 inch. The bigger the screen gets, fast action videos create more of ghosting effect and they video becomes highly indistinct. Since LCD TVs use LCD panels, many LCD televisions do not have the capacity to go fully black, rather blacks appear to be darker gray.

LCD TVs are also quite expensive compared to their CRT counterparts. Especially when it comes to sizes over 35 inch and the ones with a 16:9 aspect ratio are very expensive. However with continuous research and improvement, the manufacturing price of the LCD televisions fell and eventually LCD TVs began to dominate the market.

Though LCD TVs suffer quite a few drawbacks, there are more advantages that cancels out the few imperfections. The major and obvious advantage is that LCD televisions are easier to watch. LCDs offer more brightness and contrast than CRT televisions and perform well under almost every light atmosphere. Even under bright light ambiance, the images of the display do not appear washed out. Also, the display does not suffer glare due to surrounding lights. Since most flat screen LCD television displays can have a viewing angle of 160 degrees, the video will look agreeable from anywhere under 80 degrees on both sides.

Unlike plasma televisions, you will not have to worry about image burn-in, ideal for gaming usage. This is because colors are created using filters and the display screen is not coated with phosphor dots. Also LCD televisions are multifunctional; you can use them either as an HDTV player, home video player or as a monitor for your PC.

The screen size of LCDs range typically from 13 - 65 inches and there are brands that manufacturer displays up to 100 inches. The slim profile television is also economical in the sense that it does not require much maintenance.
