    Usual story, i have managed to get my mits on a couple of LM32P07 mono 320x240 lcd's. And yes, they are controllerless. I bought them cheap as no one really knew what spec / controller they had... (none)

    Here is the datasheets:

    I was wondering if anyone knew of any controllers (SED ones etc..) that could be used to link this in the usual fashion to a pc / microcontroller etc. It has no ram so it needs constant refreshing...

    Otherwise i shall probably just play with it making pixel sized dots manually clocking in data bits... Or fleabay them..

    Any ideas guys?
    Coorz, you seem to have the name as LCD genious...? :confused: :thumb:

    Well, at least it has a driver! It'd be hard, but you could use an MCU if you had to.

    I hope someone else can give you a controller...

    do you get lcds without anything at all? i mean all this thing has is shift registers, not really drivers as such..

    Garden variety 4-bit single panel LCD. Requires the -24V on Vee, and uses CCFT lamp. I would say about 80 percent of LCD panels with 320x240 resolution are exactly like this.

    This can be driven with a SED1335 board. But I dont know where to locate one in the UK. Coors may know.

    Precise link.
    As Hazer said; standard 4-bit controllerles, so dead easy to hook up to SED133x controller, only issue might be your -24v voltage supply.
    See the link for SED controllers.
    Or delve into micro-controllers and write your own stuff.
