I have access to a dead Toshiba 3505 laptop. The Screen that is in it is Toshiba LTM12C328T. I really want to use this screen because it is a really nice, thin setup with a wacom tablet already installed behind it.

The screen is 12.1" TFT active matrix, 1024 x 768 ( XGA ), not wide screen, 24-bit (16.7 million colors), Rotating screen.

I spent a good 3 hours trying to find either a datasheet or a controler that is confirmed to work with it. The closest I have been able to get is this:
http://www.digitalview.com/controllers/products.php

I would like to be able to have both a DVI and a VGA input. It seems that the 1400, 1600, and 1920 boards might work, with the 1400 most likely being the economical choice.

If anyone out there on the internets has experience with this sort of thing and can tell me if any of these would work, I would greatly appreciate it. Also if someone knows where I can get a datasheet for this screen, or another place that I can find a compatable controller, that would be helpful as well (and yes, I looked at EarthLCD.com, didnt seem to find what I need)


Thank you in advance for any help

Driving the screen isn't the problem with tha all-in-one tablets, it's driving the wacom side of it.  It's probably based on one of the standard wacom boards, so it's feasable that one could find the pin-outs and wire it to work.  No one has attewmpted it yet.

Definitely worth more research, I wonder if wacom might supply some answers if asked nicely?

It's possible to get a pinout from either toshiba or wacom, maybe.

Butwould the LCD controller work?

Yes. You would need to contact the seller, some controllers need reprogramming for particular panels.  After that vit's just down to what inputs and control you want.

It might be that the wacom stuff is all built into the board. That's the stuff you need to go hunting for.  If it is all built on then it ought to be relatively easy to turn it into something readable.

It's not my area I'm afraid.

cool, thanks for the info, I'll have to get in contact with the controller company.  I hope they are not too expensive.  If they turn out to be out of my price range, any tips on finding cheaper controllers?


Also, if anyone can point me towards someplace that has datasheets either on the panel I have listed above, or preferably, on the Toshiba 3505, that would be very helpful.  Something  that would be the equivalent of a service manual would be ideal.
