Hey ya'll...
I've been working with LCDs for just under a month now. I have a powertip PC2402A (2x24) LCD rigged to my server... superglued to a 3.5 to 5.25 drive bay adapter. It looks really cool with that green backlight coming of a black case in the dark. I also have 7 other displays, some with a backlight and some without, that I'm working on hooking up. The one I'm currently working on appears to be a 240x64 graphical display module from Optrex. It's marked thus:

MDK311V-0 (Bottom right)

Optrex Japan (Top right)
PWB633A-V0

and... stamped near the connection pins is:
DMF633N-CY (not 100% sure that's a "C" but it's the closest I can get)


The board has 7 "HD" chips... 6 that are the same and 1 that is something else.

HD61100A (x6)
HD61103A (x1)

This board also has a very small IC in the top left near the connection pins labeled:
C324G
9646QM13

What really struck me as odd on this display is that it only has 10 connection pins instead of the typical 14/16 (20 for some). There is a separate back light connection for it... and it works perfectally at 5V. I would appreciate any help... as google turns up next to nothing on this board.
Thanks

Your display seems as if it's controllerless as the HD61100 and HD61103 are the column and row drivers. A controller for these would be the HD61380.

Well crap. Was hoping it'd be simple to rig up. Oh well... time to start looking for a controller.
Thanks.

Does anyone have a datasheet or, at the very least, a pinout for this LCD? I have been less than successfull with the google searches. And Optrex seems to refuse to reply to any messages I send to them. I would appreciate any help.
Thanks

It indeed uses the HD61830 controller, which has since been replaced by the LC7981 controller. The spec sheet for your display is here:
DMF633
This is a 2 bit display, which is why you see less output pins for connections.

Hmmm... any idea where I can get either chip for a decent price?



Cool... Thanks.



Hrumph... is this display even worth hooking up, then?

The chip itself won't do you any good, as you would need to build the whole controller for it. It's not that hard to do and I can sell you the LC7981 IC if you want. I've built a couple of these controllers before, but don't currently have any already built.
It's definitely worth hooking up. It just handles the 8 bit input data a little differently than a 4 bit display. Still works fine though.
