Hi
I was wondering if anyone knew if and where i could get round lcd
screens manufactured or possibly the price range if i could get
someone to manufacture it for me. I've been doing some research and
all the manufacturers seem to only build rectangular ones, but yet
i've seen at certain shows / awards that they sometimes use lcd/plasma
screens that are of a strange shape. I am looking for screens with a
radius of 15 inches.
Thanx

15 inch Radius ? 30 inches diameter ? Thats pretty big ! AFAIK screens that
size get hand made at almost infinite cost.

What is the application ? What is your target price ? Is a larger pixel size
acceptable (say 1.5mm instead of 0.3mm) ?

For a one of, consider back projection

regards,
Dave

Taku,

E-mail me directly with some particulars and I'll check with some of the
suppliers I use regularly.

Quantity?
Technology: black and white/color, character/bitmap, etc.

I don't think they make them round but I'll ask the experts.

What if you were to use a rectangular one with a mask that only show a
round part of it?
Then your driving circuit only "draws" to the visible part and you're
sorted. That shouldn't be too hard to do, I would think.

When you click on the details - you get the expected answer. I was looking
for the date on the page itself - they really ought to have put it there in
small text at the bottom.

They're made rectangular (a) to make efficient use of the expensive
optically flat glass (b) 'cos glass doesn't break into circles.

Might be great for testing the upcoming beta version of
Microsoft Portholes XP ....

Glass breaks perfectly into circles. How do you think portholes are made?

There used to be round monitors in the early days of TV.

English Electric 16 inch round tubes, with metal flares, all at 16 kV or
so! They even put some in up-market receivers.

Raytheon made them on this side of the pond.

I used to throw the dead ones over the side of the hill to avoid
debris... BOOM... several seconds later... CLANG ;-)
