LCD TVs and ultraviolet (UV) light

[Guest guest]

Hi guys,

There are some awesomely smart people here, so I was wondering if anyone could

answer this question. I've tried Googling this, but I have not really been able

to find much definitive information on this topic.

Supposedly, the fluorescent backligting of LCD TVs and monitors(CCFL backlights)

produce UV light/rays. As I'm sure you know, exposure to UV light is mostly

something we want to avoid. So I was wondering if the UV light produced by LCD

screens is something to be concerned about.

Is the UV light produced by LCDs contained enough that it doesn't reach the

consumer? Or are we actually exposed to this UV light, in a similar way that we

are exposed to the sun's harmful UV light?

Is it possible that sensitive people (or even not-so-sensitive people) could -

at least over time - react to the UV light that could be emanating from these

devices?

Is it correct that LED lights and backlights do *not* produce UV light? Would a

LED-backlighted TV or monitor be a " healthier " choice - at least for some people

- for this reason?

For some reason I have in my head that a LED-backlighted TV could be the lesser

of the evils for me. I'm not sure if this notion is actually correct, though.

One thing that might contradict my notion is that - based on what I've read and

my limited exposure - LED-backlighted LCD TVs are brighter and have more vivid

colors than CCFL-backlighted LCD TVs. Since I'm quite light-sensitive, the

brightness and color of CCFL TVs are more than enough for me.

But I was still wondering if LED TVs put out a " healthier " spectrum of light -

despite their higher brightness levels.

In addition to UV light, I've recently learned that the " blue " spectrum of light

can be unhealthy too - since it suppresses melatonin production. (Blue light is

a high-frequency, short-wavelength type of light. Only the violet and UV

spectrums are higher-frequency, I think.)

Would LED-backlighted TVs/monitors put out less blue light than CCFL-backlighted

TVs/monitors?

As usual, thanks for any " light " you guys can shed.
