Plasma vs LCD – which is better for our eyesight

In Electronic on 8 February, 2006 at 5:02 am

During one of my Chinese New Year gathering, one of my friends asked me whether plasma or LCD is better for one’s eyesight.  My answer was that both are OK.  Since plasma and LCD are both fixed pixel display (meaning to say both don’t draw pixel one by one from left to right, all pixels are drawn at the same time), flickering is a non-issue.  Both panels also do not emit low-radiation and thus not harmful to our health.  Which lead me to conclude that both panels are better for the eyesight than conventional TV and both are equally good.  Provided that brightness and contrast are set to a comfortable level.

However, after giving the issue another thought, I feel that the time you spent in front of the TV is still important.  The focusing of our eyes at a certain object for too long, will make our eyes too dry and will cause myopia.  Thus after watching TV for 2 or 3 hours, one should take a break and let our eyes have a good rest, like looking out through the window at some beautiful scenery.  This way, we can maintain our eyesight and still enjoy our favourite TV programme.
