A lot of people buy LED over LCD thinking that LED television will be better because it is more eco-friendly. It can be better for the environment because of the type of lights that are used but it does not necessarily mean that it is going to be good for your eyes.
LED television is also bought more often because it is newer and they can provide better features as compared to LCD. People who have purchased their LCD television back then with very high price tags, they can still make use of their LCD screens until they stop working. This will make sure that the television will be used thoroughly.
