After LED TVs were initially introduced, they were found to have some inherent dangers in them caused by the overuse of this new technology. Since then, there have been significant improvements made to the design of these LED TVs so that they are safe for use by the average consumer.

Several studies have found that the main cause of health issues associated with LED technology comes from improper use of blue LED lights. The blue LED is unfortunately one of the most commonly used colour in television technology, even in simple applications such as the power button on the TV.
The reason that blue LEDs cause some minor health problems is something known as the Purkinje shift. The Purkinje shift describes the way our eyes are more sensitive to blue light. This is especially true in dark environments, where our eyes are more likely to single out blue or green light. Think about the way a blue light may catch your eye and distract you when you are trying to go to sleep. This is a consequence of the Purkinje shift.
Most of the effects that are caused by the blue LED are both mild and temporary. This can include headaches or a temporary worsening of vision and in some cases slight nausea may occur. As with any technology, these effects only result from overuse of this technology, they are by no means instantaneous. Though the effects are intensified in LED televisions, they are common in other televisions where blue LEDs are used for backlighting.
There have been some claims that LED technology can cause serious health problems, including cancer. While there is definitive evidence that suggests LED lights may interrupt sleep cycles and cause headaches, there is none to suggest that there is a link between LED lights and cancer. However, it has been found that blue LED lights lower melatonin levels, which can weaken a body's immune system. Whether or not this has any link to cancer is uncertain, but most companies have reduced the use of blue light in their technology to avoid these negative effects.
