Lcd Help

A while ago, I purchased a set of 5 LCD Displays from American Science and Surplus· Some of the pins were bent and I fixed 'em, but I need some info on these LCDs. I tried looking up info from the manufacturer, which was Planar Systems and Standish. I need some info or datasheets for:

Standish 9310428436542001
Planar 0038-4206-363-440-01
Planar 0102-3970-363-420-01

If no one else posts specific info on these, can you post a close-up photo and more of a description of the units?

Well, you know what they say:
· ... But that's not the full truth. Anyhoo, here are some pictures:

28 pins on each side, I think it's DIP

I know this is spam, but I REALLY need help!

Hello,

These are called Field-Effect Displays…they are LCD, but they required a driver IC to run them generally. Each element of the display is broken down into row/column matrices and needs to be energized to display that segment. This would require too many I/O pins from a typical microcontroller. You can either use an expander and try to drive them directly, or you can find a driver IC. I know Jameco used to carry one for driving Field-Effect LCD displays. Take care.

Thanks! I knew how it worked the SECOND my it started displaying things when I put it on my laptop! *Cues "The More You Know" music*.

It doesnt require any resistors does it?
I can't find a driver...
Is there another name for these types?

Here is a similar display from Jameco...sorry for the long link.

This link should (hopefully) get you the ICs that drive these displays...

This has 48 pins, 24 on each side. It's 8 digits, not 7-segment. Would those drivers work, it said four digits.

Those links were merely examples of the type of display you have and the driver chips used to drive them. You would need to look at the datasheets for some of the chips to see if they can drive your display.
