    Ahh?

    Do you have any other circuitry than the LCD itself hten? Since I only have the LCD for that and not a controller or similar unfortauntely... exdcept fo the PCB that's on the back of the LCD and I'm doubting that's a controller. Blah

    I've been researching this whole LCD thing, here's what I've learned- I'm a cheap SOB for one, but I already knew that. Whatever you start with, try to get the pinout. The hookup on these LCD's are nowhere near standardized. Finding the LCD is easy, it's the controller that's hard to find.

    I've come across industrial Single Board Computers that have LCD controllers built in, they usually support a number of different LCD's. That's nice, but you're limited by the other capabilities of the SBC, stuff like they usually are for an ISA buss. I find them on ebay for anywhere from $10 to $100 on a regular basis. Another drawback is the LCD has to be close to the SBC because the LCD cable length is limited. Also, you'll probably need to make the cable yourself because of the lack of standardization.

    I also picked up a PCI LCD controller on Ebay for $31. It only supports an 800 x600 LCD with 18 bit color but that's wha I have so I was luckey. Very few stand alone controllers get listed on ebay, and if you get one with a data sheet you're really luckey.I can drop this in any computer with a PCI slot and my LCD will work. I still have to make a cable and again, the length is limited.

    The best option is a VGA to LCD card. You can use a much longer cable with VGA, and you have better performance options on the graphics card. The drawback is they hardly ever get listed on Ebay and they cost anywhere from $100 to $300.

    Then there's the VESA connector on the older graphics cards. I never tried that because of the low number of colors.

    So, that's the options I've come up with. I'm building a computer for my car with an SBC with a pentium 800 and a built in LCD controller. The PCI card will probably drive an LCD built into the side of my computer case.

    i have the entire motherboard from the laptop (and the rest of the parts of the laptop for that matter) but in theory all i should need is the controller chip that i found.

    stupid little bugger is gonna be a pain in the rear to solder though.

    Ahh.. Darn then, since I don't have the original motherboard :(

    I hope one of the others might still work though.

    Here's what I have

    Ok, I have a 12.1" LCD screen from an old CTX Ezbook 700E.

    Here's what the back says:
    TORISAN TFT-LCM
    TM121SZ-02L01
    500C0055768715


    Here's what I found:
    http://support.advantech.com.tw/Cse...362b1af4a5e22657c82566340030f8ab?OpenDocument

    I also have the laptop in its enterity if it that helps anything. I want to use it as a monitor for a carputer so I don't really want to do the VESA 16 colors thing, but I guess that would be better than nothing.

    Does anyone know of a controller that supports this screen and where I can get one?

    I can post pictures if that will help the cause, too.

    sounds like whoever shipped it didn't know how to package it.

    the 2 pins on that that worry me the most are line clock and frame clock, which are usually indicative of some sort of digital interface

    or they could be differnt names for vsync and hsync, but i don't think so.

    yeah, considering it's meant for palmpilots and the like, i'd assume it's some weird proprietary non normal screen. but if you have the $40 to burn, try it and let us know :)

    Thanks, but it says in the datasheet what type of connector it's using (31 pin hirose).
    I thought it was similar to one I have, but it seems to be completely different.

    I've got 2 of these guys from dead Zeos Meridian laptops.
    NEC: NL8060AC26-05
    w/inverter for the CCFL

    Data sheet
    http://www.lcdspecifications.com/necpdfs/NL8060AC26-05.pdf

    Does this LCD have a build in controller?
    On page 2 there is a block diagram that shows a "LCD timing controller."
    Is it possible to use this VESA trick, or go with a video card that has a DVI plug, or am I just SOL with these?

    Thanks in advance.

    Hi!

    I have a Sanyo-Torisan TM121SV-02L07B tft screen.

    I havn't found any datasheet for it but as it is connetet do a laptop right now i can see that only 8 wires goes from the motherboard to the screen. Why so few?

    there are about 13 wires that goes from the motherboard to the inverter, i suspect it is for adjusting backlight and contrast.

    Could it be that it only needs RGB, h-sync, v-sync, clock and som power to work?

    I guess im bringing back a thread but i dont know much about laptops but all i know is i have a lcd that would go great on my case but anyway. Is there anyway to use a mobile video card to run it. I dont know much about how laptops connect to gfx cards and such but just wanted to know if there was any possiblility.
