  • My last displays (not from sparkfun) have a epson-controller. It was much too bright, contrast control did not work.
    I discovered that it works if you connect 1 with 6 but not connect the two pins to any supply.
    Now contrast works, all colors fine!
    I measure 1-6 to GND 2.85V. Seems that LED V+ supply the whole display.
    PS: I have 100nF from 1-6 to GND.

No public wish lists :(
