    Connecting/power/controlling LVDS LCD directly from motherboard

    Hey all,

    I'm looking to install a simple CarPC in my MX5 with a double DIN mini-itx enclosure and 7 inch display (think ByByte), I was looking for my own display directly from China most likely and came across the Mitsubishi AA070MC01. At the risk of sounding like another 'will this display work' newbie, I have a slightly different take on the question.

    Now I know the measurements for that display are 170mmx110mmx9mm (near as damnit) so immediately it's 10mm bigger in height than the standard for double DIN which I believe is 100mm, but I'm hoping to measure out and find a way of mounting it so that it won't matter so ignoring this point, the display is listed as being a single channel 6 or 8bit LVDS display with a 20pin connector.

    I was looking to use the Intel DH61AG motherboard which happens to have an LVDS connector onboard and additional connections for LCD power/backlight power/backlight control however, the LVDS connect is a 40pin connector so I am confused, perhaps this is because it also supports dual channel LVDS? But the pin outs also seem different so I'm not sure if you can by pre-made 40pin -> 20pin cables or if it would even work?

    Your thoughts are much appreciated.

    There is a note, that single-channel output is driven from the odd signals. I'd be willing to bet that ODD_Lane0_N is Link 0 - (n for negative), and ODD_Lane0_P is Link 0 + (P for positive). The rest of the signals seem to line up, but I'm no LVDS expert so i'm not entirely sure... but it seems like that may work.

    Yes that would make sense, I guess then it's just a case of getting a cable made up since I doubt I'd be able to make the correct ribbon cable!

    Curious, my initial response doesn't appear to have shown up yet, perhaps it's a new user thing and needs to be approved, lets see if this one is different.

    I guess I just need to get a cable made up to connect the panel to the board and also one for the power/backlight control, the question is where would make these flat ribbon cables?

    The LVDS and FPC connectors on the apple gate boards is what would be considered non typical. (at least for now).

    There is no known source to buy parts to diy a cable, and the only company that I know of that will make one is
    Quadra Angle (www.quadraangleproducts.com).

    They charged me 80+ for one pc. w/flying leads that I terminated to the LCD side.
