Hi Didier, please do not dismiss the concerns of scientists that may have a point. There is some substance to the concerns for home viewers who would be exposed to overexposure covering average 3-4 hours a day of TV viewing and maybe seven days a week, and maybe many years. So it cannot be said there is no safety issue and it is being watched carefully. This is uncertain ground the electronics companies are treading in. Being sensitized to something can happen overnight, and there is concrete evidence of computer LCD exposure and excessive use to confirm that you would no longer be able to use a PC or laptop or even work in an office at a computer workstation. All serious stuff if you take the trouble to read as I did.
Strobing and flash photography affects the brains impulses, unless of course Didier you don't have a brain, so there wouldn't be much to worry about

Its a physic fact put two indifferent beating oscillators in close proximity and in time they will synchronise. If a PC CPU is not clocked correctly , then corruption occurs, and a human being's brain is just as susceptible so your motor functions and even heart could go haywire, hence the concerns with pshzitzo types who are at risk with similar situations.
