LCD monitors use mercury in fabrication; mercury is toxic and harmful both to the environment and to humans. LED monitors also use less power than LCD, in some cases (if your television or monitors is constantly on, like clubs, bars and waiting rooms) the energy savings is enough to make up the price difference between “LED VS LCD”. LED TVs and monitors have better image quality, better resolution, are thinner, are also better for the environment, and lighter to boot! But, LCD televisions are cheaper right now, so that can still hold its popularity in third world country like Bangladesh and Indonesia.
