    Nl6448bc20-20

    Anyone have a datasheet on this display.
    I also have a 65PW061 inverter.

    I know I need a LCD controller (LVDS not available)
    size Scrn Resolution Model # Interface Max Color
    6.5 640x480 NL6448BC20-20 CMOS 6 bits 262K colors


    Which LCD controller would you recommend?
    How do I plug in the inverter to the outlet(what type of cable)?



    There isn't much on this LCD.

    Try to search for similar types. The pinout usually the same or very similar. Check GNDs and if match, you won.

    I recommend pcix69000.
    The only problem with ttl rgb driving is the max. cable lenght, that is approx. 50-60cm (20 inches). Over that size noise and crosstalk makes the picture wrong or the display is even unable to show the picture.
    Skipping this problem, the card I suggested also contains a SIL chip, that provides a TMDS transmission at the same time, but in that case you need a receiver board (approx. 3x3 inches). The advantage is, that the supply of the display AND backlight and display data are in the same cable. Of course, you need a special cable also, but the max lenght is about 15ft.
