Hi All,

Does someone here know anything about these displays -> Wintek WM-G2412D (T6963C) or Wintek WM-G3224Y (NT7761 driver chip)?
I've 'googled', but have not found any infos. Mainly looking for hookup and spec sheets.
They are selling cheap and I was thinking of buying one if it was not junk.

Regards,
Iridium

Have you asked the seller for a datasheet?

If however no-one can find the data sheet. It shouldn't be too hard to work out the pin out for the T6963C controlled one, as long as it's a chip and not a silicon wafer in a blob of epoxy.

Ya, I thought the T6963C might be somewhat easy to figure out. I have never heard of the NT7761.
Sorry, I forgot to mention that the seller has no data whatsoever on these displays

Thanks for the reply Syridian !

Regards,
Iridium

I guess this http://www.wintek.com.tw/products_lcm_graphic.asp should put you on the right track (with a multimeter )
Some pix of the big one (PCB side) would be nice.

Those model numbers sound familiar. I remember seeing the displays sold and did have a quick look around for specs but wasn't able to find them.
But I remember the info I found for the bigger one was that the display was a 3.3v device so the controller board (yes you need a controller board) needs to output 3.3v I/O levels.

Well, I see coorz hit it on the head! I don't know how I missed that!
Went to the Wintek site earlier, but didn't see that page. Thanks coorz!
I wish had pics of the backsides of both.
On a side note: Coorz, your display artwork is awesome! I wish I had your talent. I'm still using an old version of LCDInfo as I haven't been able to understand XML in the new version. And the designer frequently crashes on me.

Hi

I've got my hands on a LCD like the one Iridium talked about... the WM-G2412D Rev.3.

I've look at it, and it has one T6963C ic, three T6A39, two T6A40, one Winbond W2465S-70LLa nd finnaly a small BA10324AF.

At Wintek site, i could only found a WM-G2412E, but its the same size, and with the same backlight... altought i cant be shure its a different Model. The Only info i have available is the following:

"WM-G2412D Large Graphic Display Module with CCFL Backlight. Made by Wintek this large 3.67" x 6.59" graphic display module has 128 x 240 dots. Has built in T6963C controller and various other ICs for driving the display. Backlight tube is a 3.3"L white tube which requires an external high voltage to drive."

In Henri schematics page for the T6963C it says something about a -8v supply for contrast... but here is the Info about the wintek WM-G2412E:

+5V Power Supply
1/128 Duty Cycle
Dual Power Supply
Direct Lighting Type CCFL Backlight




Item Sym. Condition Min. Typ. Max. Unit.
Supply Voltage for LOGIC VDD-VSS Ta=25 Deg.C 4.75 5.0 5.25 V
Supply Voltage for LCD VDD-V0 (VLCD) Ta=25 Deg.C ----- 19.0 ----- V
Supply Current for LOGIC *IDD VDD=5V ----- 15.0 25.0 mA
Operating Temperature TOP ----- -20 ----- +70 Deg.C
Storage Temperature TST ----- -30 ----- +80 Deg.C





01 02 03 04 05 06 07 08 09 10
FGND GND VDD VEE /WR /RD /CE C/D NC /RST
11 12 13 14 15 16 17 18 19 20
DB0 DB1 DB2 DB3 DB4 DB5 DB6 DB7 FS RV

I've wire it like the schematic on T6963C Henri provide in the Homepage, but i cant get anything to show... any hints ?



btw...here are some pics of the LCD:

In the information you posted it says 19V typical for VLCD (VDD-V0) so with VDD of +5V it would mean about -12V to VLCD as the contrast voltage.

I just purchased exactly the same Wintek lcd, same model and revision number. I posted a post in the Hardware section with the pinout that I received with the lcd http://forum.lcdinfo.com/viewtopic.php?t=1111

I have not tried hooking it up yet, waiting on pin headers, etc for wiring. I do have a few questions, and I would appreciate ANY help from you guys. I bought a powertip from Mingingbollok a few months ago, but it was already wired, so this is my first wiring job. My BIGGEST question is how to get the neg. volts for Vo. The powertip I have just has a 10k pot hooked up, would that also be sufficient for this display??????

Iridium, if you want the pinout for your lcd, go to my post above. I have also emailed a regional sales manager in Calif. for the tech/spec info, he emailed me back and said he would email it to me tomorrow. When I get it, I will post it for you.

Iridium, I have a .pdf spec sheet for our LCD. It was sent to me from a regional sales manager for Wintek. It is not for the exact model we have, but he assures me it is VERY close, if not exact. If you want a copy, email me: razor@carolina.rr.com

Is this data sheet for the WM-G3224Y (NT7761 driver chip)? If so, I would like to get a copy as well if possible. Thanks

I have a Wintek MG3224Y-1NFWbV1.pdf sheet. Just holler.
