and without realizing it before, this laptop that ive had since 2012, which im using now has LED backlighting in the screen....and ive only just disovered it now by reading an old instruction manual.

all the time in those years ive been using this laptop, looking at the screen, and its had LED backlighting......the laptop is a toshiba satellite.

can anyone calm my worries?, is it true what this guy on the internet has said? is LED lighting harmful to humans?
