Lifespan of LCD TVs

LCD stands for Liquid Crystal Display. lcd tvs are quite famous over the recent years due to their fault-less clarity and picture perfectness. Usually it is said that LCD has a greater lifespan than plasma TVs. But that does not mean that lcd tvs do not undergo wear and tear at all and work all through one's life. They too can undergo problems and other faults just like any other electronic device does. They generally work based upon the twisting and untwisting of the crystal.

The normal lifespan of lcd tvs is said to come to approximately 60, 000 hours. Some manufacturers also claim that their LCD TVs can last up to 80, 000 hours, when used under controlled conditions, like the room temperature, the other climatic conditions, the maintenance conditions etc. The display effect of these LCD TVs would definitely reduce as time passes by, because they are constantly being lit by powerful lights that could dim, just like the other electronic devices, over a period of time. This results in the picture getting dim as time goes by. Hence, the most important thing to be considered in an LCD TV is the actual lifespan of the light source of the LCD. There should be good warrantee provided for the light source of the LCD TV as this is the mean thing that controls the picture effects and clarity.

The quality of this light source is important to maintain the perfect white balance in the LCD TV. The back lighting bulb should be definitely of higher quality for the longevity of the TV. So it is better paying more for the branded ones that offer exchange or maintenance warranty rather than the cheap ones that do not have any warranties on them. Also the contrast levels have to be taken care of. The more the contrast levels, for a longer period of time, the faster the TV would age off. The lower the ambient light levels, the more the life of the light source.

Some Sharp LCD TVs provide separate units that have the light source, whereas the others have the light source placed along with the other units and so if the light source is out, the whole LCD TV becomes a waste. The main thing to be considered here and always to be remembered is the warranty of the back light. Unlike the other types of television the LCD TVs cannot be used for the whole lifetime because of its limited lifetime. The light beams are the main source used in the working of an LCD TV. When compared with the plasma television the LCD TVs have a short lifetime and the maintenance of the device is also easy when compared with the normal televisions.
