Re: Design a VGA control board for an LCD.

Actually, mine is the version 01 instead of 02 of the LCD, this link is
better:

It now seems to boil down to how to generate the "dot clock" signal
from the VGA signals .

Any comments ?

Thanks,

I have a NEC NL128102AC31-02 LCD. This would describe what it is:

I think it's almost VGA ready, unless...

Thanks for your responses so far.

Hi,

I currently have an 21" NEC LCD that can handle 1280x1024 of
resolution. I'd like to build a simple card to accept VGA signal and
control the LCD after that.

I saw some off-the-shelf controller card, but they seem to be expensive
and not very widely available for ordering.

Is there other off-the-shelf IC or card that can do such a thing ?

Thanks.


I'm not entirely clear what you're after. Are you saying that you just have
the glass and want the interface card, or do you have the whole monitor
without a VGA input?

Digital View makes interface cards
http://www.digitalview.com/controllers/products.php however I'm not too sure
of the current pricing, or availability in small quantities. I redesigned
the model MAV-1280 LCD card for them in early 2000 to get it to pass CE, and
I can tell you that there is nothing simple about it. You will also need the
inverter board to operate the backlight.

If you know of a monitor which uses that glass, you could look for a broken
one on eBay to get the driver boards.

not 100% sure of the question either, but here is a potential answer:
