    Are they not similar to Raymans 4.3" LCDs just without Touchscreen and maybe with another pinout?

    They are basically the same, the connector is different: while it is also RGB based some need 3.3 and 5V besides the backlight voltage.

    I think they are very, very similar. I'm tempted to make a board for them, since I'm running out of my "used" screens... I'm still on the fence about it as they are a bit expensive. But, I think there are cheaper clones out there...

    Rayman, here they can be had for some 20 Euro on that auction site (TAS :). But as I said they have 2 VCCs :)

    SparkFun sells them. They also have a touchscreen to go with it.

    SparkFun has datasheets for both devices.

    I am using them with Rayman's code for the 4.3" he sells unmodified. The only difference is the voltage for the BL, if I remember correctly. It does use a different (smaller) connector, however.

    Cool. Where can I find Raymans code at. I ordered one of theses lcd's from sprk fun. And I was REALLY hoping someone had some propellor code already for them. Im not that good with programming and I would take me forever to write code to make it work.
    thanks

    Now that I think of it... I'm actually using Andy's code... which I think might be a derivative of Ray's code. Andy's used a different backlight scheme that allowed me to set it via a variable.

    In the long thread about Raymans 4.3" LCDs. See Link in post #2 of this thread.

    There is a short version of this thread. See the hint near the end of the long thread.
    I have several drivers posted there, I think Bill uses the graphics driver that works with Chip's graphics.spin.

    Bill
    My code is not a derivate of Raymans driver. My driver is based on Chips VGA bitmap drivers, and Rayman's on Chips VGA tile driver.
    So both are derivates of Chip's work ;-)

    Ah... I remember now. You're correct, I'm using your Graphics driver. I think because it was full screen (2x pixels.)
