The future of displays?

[John Woodgate]

I read in sci.electronics.design that Jan Panteltje

Get lost ego tripper, you bring in nothing in this discussion on displays.
PLONK

I think I was the second person to respond to the OP, with my
predictions.

I get plonked for saying that I WOULDN'T make an unkind joke about
someone? That's a bit hard. I'll cry in a minute.

Seems to me that someone who had a serious interest should go check
out the SID proceedings for the previous 5-10 years, then (maybe) come
back with questions about specific emerging technologies.

What are the SID proceedings? Google is your friend.

LEDs are unsuitable for powering video projectors for several reasons:
1) - The efficiency is only about that of halogen lamps(<27%), a much better
choice would be HID with 2-3 times the light output for the same electrical
input power. The same need for a fan.
2) - The required power would dictate the use of at least 30 5W Luxeon LEDs
with a lifetime of only 1000h, costing at least 1500$.
3) - The spectral distribution is not even, so special flourescents and/or
filters are needed with lower efficiency.
4) - The power supply is not suitable for LEDs and additional components are
needed.
5) - The emitting area is much bigger and therefore difficult to focus.


Well, if they were suitable for the application don't you think somebody
else would have already had the idea? BTW I wouldn't like to be declared
stupid either.

I remember years ago when colour LCD displays were just equations being
worked on. I'm wondering what I can expect in the next 15-20 years.
Will it be more of the same, but bigger, lighter, and flexible? LCD
monitors seem good enough, now, for just using a computer. LCD
projectors seem good, but need bulb replacement so how about LEDs
instead?

I am more thinking about displaying extra information other than
intensity, like holographic displays (colour or monochrome) and
possibly reflectivity so you can get good metallic colours. This would
go down well, I believe for shopping channels.

Capturing information to display a hologram is another issue.

The future IMO should have arrived some 15yrs ago.
I put on a headset with a device the size of a pack of chewing gum over one eye
and saw a 720x350 (IIRC) mono display hanging in the air in front of me.

Why this tech has never caught on for PDAs and phones I have never understood.

How about the looking-like-a-dork part? Try putting it beneath a
cool/cute visor instead.

Why should you, of all people, be concerned with party alpha's
perception of party beta's appearance of dorkiness? What do you care
what other people think?

I care about all parties because they exist and are influential. And I
don't tolerate the ugly.

How do you feel about mirrors, then? (;-)

Yes this is nice, and I already considered on, light output needs to improve
for big screens.

This is about an old demo (12.16.2003).

There seems to be some difference in the way we (our brains) proces sounds and
vision.
Here are some basic things to think about:
When you sleep the ears keep working (sort of alarm system?), but the visual
info is 100% closed of, except for strong light (sun up signal?).

We can do all sorts of things and listen (be exposed to) music or speech at
the same time.
We cannot possibly do anything while at the same time reading for example.

When you use a device like you describe on a cellphone or PDA, you will be very
much stuck to sitting where you are.
Moving around with a superimposed picture, even one one eye, would be dangerous.
Of cause data projections like this are used in mil planes for all sort of
flight data, but they probably do not play Goldfinger.....

So maybe at home. But do not spill the coffee when it is handed to you and
you are watching 'Liberation day'.

They're cool. How do you feel about haircare?

Then why haven't you reported to the nearest cemetary?

Actually, if it's pronounced "ell-ee-dees", then the apostrophe _is_
correct, in this case. If it's pronounced "leds", then it's not.

I can't help it that I remember all this crap from fourth-grade
English, I just do.

Thanks,

Maybe somebody said, "How much will it cost us if somebody's using this
in their car and decides to sue us when they crash?"

The last I heard, it is illegal to have a TV in a car where the driver
can see it.

There's no such thing, and you make fun and rubbish when you're jealous.

obsolete... LED's is eleedee's.

Try telling that to all the dead people who reside in such places.
