    Hey. I have a question. I have an 18 bit panel as well. Let's just use the blue signal to illustrate my point.

    The LCD has pins for blue 0 (LSB) through blue 5 (MSB). The controller has pins from blue 0 (LSB) to blue 7(MSB).

    Do I connect them 1:1
    LCD-Controller
    B0-B0 (LSB)
    B1-B1
    B2-B2
    B3-B3
    B4-B4
    B5-B5

    or

    Do I connect them
    LCD-Controller
    B0-B0 (LSB)
    B1-B1
    B2-B2
    B3-B3
    B4-B4
    B5-B7(MSB)

    Or something else entirely?Thanks!

    Hey this is the cable that I need for mine huh? Looks like it has the hirose female connector to plug into my sharp367 on one side and empty ribbon cable on the other end? PDF:

    Hey DDT,

    You need:

    R0->R2
    R1->R3
    R2->R4
    R3->R5
    R4->R6
    R5 (msb) ->R7 (msb)

    Basically the most significant bits have to match up because it is telling the red level in binary, and the panel can only handle 0-63 while the panel can handle 0-255. So you just chop the bottom insignificant bits off the 8bit value to get the 6bit value..


    And Cordell,

    Yes that cable will work, but Quadrangle may be expensive.. Get a quote none the less.. I emailed some companies about discrete wire cables so we'll see what they say..

    Well, I am not sure about any other panel but my panel is one to one starting with LSB... B0 goes to B0, B1 goes to B1, etc... This only makes sense to me because if you are using binary numbers and each color can see 6 bits of data, you will have 64 possible color levels. Now say you wanted to set red to color level 45, you would need to put binary value 101101 on the six red lines starting at the LSB. If you looked at all 8 bits, you would see the number 10110100 (this is the same number in binary if the LSB is on the left).

    That is how I see it anyway.. (but, I have been completely wrong in the past)

    That pinout is exactly like mine... Why dont you try both ways and see which one works, you wont hurt anything.. It will display funky color levels if you hook up the color lines wrong.

    ddt, I wondered about that, too but I came to the reasoning (after looking at other 24 bit controllers) that it would be connected 1:1. I have a similar panel (essentially - contrast and brightness are different but they are the same pin out) that I researched the pin out info for.

    Well I'm about to start the tedious take of soldering and heat shrink wrapping 31 wires. I think it'll be 1:1. We'll soon see...

    Are you actually considering soldering directly to the Hirose connection on the panel? That would be borderline crazy to attempt.. Good luck, I hope you didnt drink any coffee for the last month...
