Hello,

There is one big problem with CRT's, LCD's and possibly even televisions...

They all project lot's of light into our eyes, which screws with our
wake/sleeping pattern.
(Especially large white area's on the screens.)

Maybe analog/non-light displays could solve such "health" issue's.

Bye,
Skybuck.

They do say that e-Ink displays are easier on the eye. To judge from the
current market, we'll all get the chance to find out in the next few years
or so.

You can and SHOULD turn down the intensity of the TV screen to fit the
environment in which you are watching it. That is if a human being
were to stand besides the TV screen with an image of a humam on the
screen, both should display similar intensity levels and skin tones.
100% of TVs leaving the factory are set way to bright.

But the fault is that of the user, wanting colors that are too
saturated, too bright, and not at all realistick. All TVs that I have
seen in the past 20 years come with a control unit tha allows the user
to FIX the color should he not be so blind as he cannot correlate
reality with TV.

TVs are typically shipped with default display settings that are way too
bright, over sharpened and too contrasty with posterised colours. That
is apparently what the slimy marketeers have determined sells most kit!

I guess they have to be bright to look good in shop windows.

You can adjust these settings to get a sensible real looking default
picture. A few of the newer ones now dynamically vary the back light
brightness to enhance to total luminance range displayable and/or
respond to changing ambient light levels automatically.

I can only agree with you. Some of the better LCD displays use IPS
panels and they offer a noticeably wider colour gamut. The other
advantage is that people can see the display with accurate colours from
a wider range of viewing angles. I find this beneficial too.

I just read an article that claims that if we go to the bathroom in
the middle of the night, we should use a night light instead of
turning the lights on. But the plug in the bathroom only works if you
turn the lights on, so people will have to use up flashlight batteries
to avoid getting cancer from light overstimulating their brain cells.

I doubt, though, that this is as bad as smoking.
