Most desktop LCD screens use CCFL. I think LEDs are occasionally pulsed for increased brightness but I am not certain. I think this technique is most often used on things like car blinkers and traffic lights and not displays. However I use this technique for my LED matrix screens in electronics class.

If there is no sound in space, how come you can hear the lasers?

Is this a joke? You might as well say 'go sit under a tanning lamp for a few hours and tell me how you feel.' Both use fluorescent technology after all.Go stare at a fluorescent light in your office for a couple hours and let me know if it strains your eyes, Wiggy.
You may be confusing eye strain with what is normal for ANYONE reading for a long period of time. Eyes cannot focus on text for as long as you do -- even if you were reading paper.I frequently complain of eyestrain. I have to take out my contacts and put on my glasses as soon as I get home, and I frequently need to take my glasses off and rub my eyes from LCD eyestrain.

So do most displays. That's the 'F' in CCFL.Originally posted by Wiglaf View PostIs this a joke? You might as well say 'go sit under a tanning lamp for a few hours and tell me how you feel.' Both use fluorescent technology after all.

I honestly cannot believe this. You think sitting in front of an LCD will give you a tan? I can only assume you are intoxicated.
Try reading a book for 8-10 hours. You will have a headache even if it is the Bible, I swear to god. It is natural to not have to FOCUS YOUR EYES ON SOMETHING CLOSE TO THEM FOR LONG PERIODS. Do I really need to explain why this is evolutionarily and physiologically true?

I didn't say that. Staring at a tanning lamp will also give you eye strain.Originally posted by Wiglaf View Post

Wiglaf, fluorescent lights have filters (phosphorous, specifically, I believe) that essentially turns the UV rays into the visible light spectrum. Tanning beds do not. So no, you will not ****ing get a tan from your LCD display but they do use the same general technology.If there is no sound in space, how come you can hear the lasers?

Right. So if the manufacturer forgets the filter, you would get a tan. Why do I not believe you? If this were true every LCD manufacturer would have an option to ship the monitor without the filter.
Look, I read all day. I spend 4 hours each morning reading through The Hill and Politico's print edition. I have to take breaks even though that's ink. Does no one else experience this?Comment

WTF dude. No one is going to accidentally forget the ****ing filter on your fluorescent lightbulb. It wouldn't work as a light very well either.If there is no sound in space, how come you can hear the lasers?

Why not? Have you ever been on a tanning bed? It is pretty bright?Originally posted by Hauldren Collider View Post
Funny you call me retarded, but you do not read as much print materials as I do and that is your way of covering for it instead of disproving me with facts.,,Have you considered you have mild mental retardation?

Personally I can roll out of bed in the morning and read until I reach the point of physical exhaustion, it doesn't bother my eyes at all. Then again I don't often read for more than a couple of hours on a daily basis.
Thank you guys for the on topic responses, and thank you Asher and Wiglaf for being yourselves.

I love the silence, because no one can explain why I am wrong. They just say 'WTF you dont know anything' and I exposed them.
But if you tried, you would probably have to "rub your eyes" like Asher does too.Then again I don't often read for more than a couple of hours on a daily basis.

Oh come on, Wiggy, we all have to rub one out sometimes."The issue is there are still many people out there that use religion as a crutch for bigotry and hate. Like Ben."
