Hi everyone,
I´ve found this LCD among some old stuff at home. I remember that I got in junkyard (a day-trip with my old men) but I can´t remember what was attached to it, if to a UPS or some type of printer. Meanwhile I forgot it and now I “re-found” it and I was wondering if it possible to put it to work. I´m no electronics expert/technician but I believe that I can make it work but I need help.
This is what I found (Googled) about it:
- It´s a 128x64 graphic display;
- DG-12864-53 from DATAVISION (in the PCB there are two references : DG-12864-53 and 1264-45A S2FTLY-AP on a sticker);
- It uses KS0108;
- It´s attached to some controller board that I couldn´t find any (valuable) references in the internet – P306A, Phico M-0, 0235 94V-0, ELECTRONICS FOR IMAGING Z18 USB UIB.
In the DATA VISION website I “decoded” (http://data.s520.com/en/code.php) the graphic display reference DG-12864-45A S2FTLY-AP:
DG – Graphic LCM;
12864 – Graphic resolution 128x64;
45A – Series No.
S2 – LCD mode Silver gray, STN;
F – Polarizer Mode Transflective;
T – View direction Top View (12H);
L – Backlight LED;
Y – B/L Color Yellow-green (EL,LED).

Bottom line, what I want is to connect it and use but I can´t find a cable (or schematic) suitable to do that. I´ve found some on the forum but I don´t know if a “linear” adaptation can do the trick and I´m afraid to blow everything up (between other things) :P

The board where the display is attached (solded) has a connector (3M3793) that I believe that could be used to connect to the PC (trough USB, because the board also have an USB controller – CYPRESS AN2131SC) but the only reference I got to this is in some L-Band Synthesizer project http://www.teledynemicrowave.com/pdf_broadband/9717_L-Band_Synth_without_Aux_1205.pdf.

Can anyone give me a hand or point me to the right direction?

it looks like a KS0108 based lcd

OK, working on that basis a using Henri diagram (http://forum.lcdinfo.com/viewtopic.php?t=286) for Crystalfontz (CFAG12864B-TMI-V), I come out so far with this Image and now I have serious doubts about the remaining connections (pins 2, 3, 6, 17, 18 an 19) because the supplying voltage its different.



Also I find out that the IC (SCI7661M0B) Image I thought it was a negative voltage generator is really a "booster that generates a doubled output voltage (-3.6V to -12V) or tripled output voltage (-5.4V to -18V) from the input (-1.8 to -6V)" (and I think is not only a booster but also a negative generator - like I said earlier, I´m a noob) - SCI7661M0B Data-sheet http://www.datasheetarchive.com/pdf-dat ... 174650.pdf


Those are the voltage and pinout table Image , can you give me a hand filling up the gaps I have? Please?

Hello again,

Looking at the main existing schematics for KS0108, I adapted almost all the connections (and I think they are correct)... Image

But I don´t know one thing:
- What value for the variable resistor should it be used (since Vee= -10v and regarding the general voltage table) - perhaps 20k?.

Thanks again.

you can get the lcd modules datasheet easily by google.
