LCD vs LED TV Lifespan

It is generally claimed that an LCD TV would last in the highest condition for around 75,000 hours. This is just an average estimation, and some LCD TVs could even last longer, if the conditions are right. There are several external factors that could affect the lifespan of an LCD TV, and the temperature in the room where it is kept, and the manner in which it is used, are the most prominent ones. LCD TVs are backlit by fluorescent lamps, and it is a fact that over time, these lamps become dimmer and less effective, and this affects the quality of the picture that is produced. This is not the only problem that LCD TVs face over time, as the color output of the TV is also affected after some time, and this will require one to calibrate the LCD TV with alarming regularity, after a few years.
When it comes to LED TVs, the light source does not stem from the fluorescent lamps, but from LED lamps instead. This bulb technology is superior and longer lasting, so LED TVs do tend to win an LCD vs LED TV lifespan comparison. The problem of the bulbs getting dimmer over time and the color gamut getting affected is also not as intense in LED TVs, so they do represent the better buy since they last much longer. LED TVs are costlier than LCD TVs though, so this price difference is one that the buyer must be willing to bear. It is generally assumed that an LED TV offers around 100,000 hours vis-a-vis an LCD TV. But you must remember that this lifespan depends highly on the level of contrast that the TV set plays at. A higher contrast setting leads to a shorter life since the LED lamps have to work harder to produce the same colors, and this contrast setting will highly depend on the external light ambiance in the room where the TV is viewed.
