Schematic for Laptop LCD from VGA port

nbk13nw · 13-August-02, 04:27 PM

Anyone have any ideas on wiring a Laptop LCD to be able to push video from either a VGA or video source. I have seen it done before.

RORSCHACH · 13-August-02, 06:34 PM

i wanted to do the same thing but never got any information about it so i saved some money and finally replaced the laptopÃ‚Â´s mobo and processor, maybe if i find a really old laptopÃ‚Â´s screen iÃ‚Â´ll try it again

I've always wanted to try this as well. I have read on many other sites though that you have to spend a lot of money on special controller boards to change signal and allow it to work. Try searching on google.com

if i remember correctly lcd screens from laptops are not standard vga at all and i believe you need to buy a special adaptor circuit which costs the bomb. if you find a way of doing it do let me know as i have thought of this idea before itd be nice to place on the mobo side of the case where there is no window have a fishtank look to it or something.

ah someone else has asked the million-dollar question.

I'm pretty sure its not possible without a controller.

Well I actually did make a VGA laptop monitor using a schematic that I found on a no name message board. Fortuantely for me I had a broken desktop monitor with a similar pinout so I just had to rewire it.

I'll take a pciture in a second but there is not much. It just looks like a monitor.

EDIT: I dont have my small screwdrivers with me so I'll get the pics another time

shame really so many of us lack the $$ to buy an lcd specially yet we all have that old laptop we wanna use

tim_programmer · 21-January-04, 05:16 PM

aah u replied faster than i did lol... anyway, u managed it.....please tell me u have a schematic lyin around

Gamma_Goblin · 21-January-04, 06:11 PM

Well i actually dont have "the" schematic lying around (I lost it in a reformat). The odds are that you wont have the same LCD either. You have to look around google for the schematics or pinout of THIS MONITOR SERIAL NUMBER/NAME and keep varying your search til you come up with something. Sometimes the manufacturer of a product will have a schem for you.

Plus I actually did use a controller card, it just happened to be stolen from a very old broken desktop LCD monitor.

An lcd controller will costa hell of a lot. Almost as much as a new LCD monitor, unless you get lucky and have a certian type of LCD.

Hurt Me Plenty · 29-January-04, 10:24 PM

Do you have the laptop motherboard? If you then you already have the controller board.

That is what I got here right in front of me.

My lcd screen uses a DS90363AMTD controller chip link

the only other issue I have before implementing this idea, is the power.
Which is another connector, which means I just need to figure the pinouts.

anyway, I digress.

If you know who made the lcd screen, perhaps you can get a schematic, of the lcd or perhaps the laptop's board. You would be surprised of what you are able to find or reverse engineer these items.

I seem to remember someone posting the pinouts for an old analog tft screen, but I cannot seem to findit anywhere... anyone know where I can find it? any help would be greatly appreciated

I had a broken laptop i was thinking the same thing let me know if you get it sorted

Okay, you did this, but how? Wiring pin-outs, detailed photos, or a schematic would be helpful. I've seen your pics but I can't really make out anything in detail. What LCD did you use? How did you wire it up? If you da pimp, share da ho's!

Standard VGA input and 12V converter directly to PSU.

So thats just a regular desktop LCD right? Otherwise where did you get the circuit board?

Coelacanth · 20-July-07, 09:44 PM

Looks to me like the circuit board comes with the LCD, at first I thought it was an adapter but now I don't think so...I think one post could've explained everything, but maybe it's a mystik mod secret or something.
