help with huge display

[lucas_siglo21]

i got from a friend a very old and big display from a notebook, it is graphic.
the thing is that i can't find information, nothing ahout the displays or the ICs in it, it has 15 pins, i took a couple of pictures, i put there a 20x4 display so you can compare the size.





if you know something or you can find some information it will be wey appreciated.
the only thing i could find is the pinout of a toshiba display, different from mine but from the same age, similar characteristics and same quantity of pins:

Code: Select all

* 1: GND
* 2: 50 Hz (Uitgang LCD)
* 3: FRAME GND
* 4: Line
* 5: Data Shift (Pixel Strobe)
* 6: Logical Ground
* 7: Data 3
* 8: Data 2
* 9: Data 1
* 10: Data 0
* 11: Logical GND
* 12: +5V
* 13: -17 - 19V
* 14: -21V (Contrast)
* 15: GND

Nice find, but I can't help either.
Seems to be a scanning display, pretty much like PAL B/W tv sets.
When and if you can find the datasheet, you will have to build a controller for it with ram for the display data and character set. I'm pretty sure this display wasn't thought to be connected to a serial or parallel port.

Hope you'll get this working one day!

yes, in lcdstudio forums they said that i have to do a controller board with a SED133x controller, it would be possible but i can't find that IC, i've sent a mail to the major electronics distribuitor of my country, they didn't answer yet.
and that controller is QFP, it goes with a memory, and i can't make those PCBs, the clearances are too small.

everyway, there is someone that makes usb sed controller boards like i need but he is in finland, i am in argentina.

yes, it was tought to be used as a monitor for a notebook, an old notebook. the display has 20+ years, it's older than me!.

but connecting this display would be great, i think it is 200x640, that's a lot, more than anyone could ever need.
