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

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.

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

What use they'd be is anyone's guess.

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

Portholes or potholes?

D'oh! I've been trolled by a website.

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.

I though perhaps the OP was thinking of an LCD with polar co-ordinates.

For something like a sonar scanner for boats.

Interesting technical challenge...

Actually, 3" round LCDs would be a great innovation.

Aircraft instruments are 3" round, and it is impossible to
find them to make compatible instruments that fit in those holes.
The ones that are available usually are square, and require the
panel be modified.
