    Purchased a Hantronix HDM16216L-7-8C0 display. Unfortunately I am not familiar with where to find pin 1 and other pins and the data sheet is no help. There are 6 pin soldering holes on one end and 5 (on is not connected) on the other with 16 along one side where the circuit board extends further than the other side. Perhaps there is an industry standard means of labeling that I am not familiar with.
    Can someone help?

    The 16-pin side is the correct side for interface signals.

    You can find out the exact pinout definition in the datasheet. The common LCD interface uses 14 pins, excluding the backlight LED connection. I have marked these two groups with different color.

    Note particularly where pin#1 is, which is next to pin#15.

    the 16 hole connection is the connection you want for controlling the display, most LCD's have a standard pin out..... the way that particular LCD connection is, seems to be a little different than most, they have pin 14 all the way to the left, and pin 15, 16 is all the way on the other end before pin 1 so it goes (left to right) 14,13,12,11,10,9,8,7,6,5,4,3,2,1,15,16.

    Pin 15 and 16 is for the backlight, the rest is as follows (which is clearly represented in the datasheet)

    Caveat! I have not seen this particular pinout before... The 16 pin single-in-line interface on several different 2x16 and 2x20 displays I have are numbered 1 through 16, consecutively...

    Head slap! Thanks to all! On re-examination, I simply missed it AND I looked right at the diagram-ugh! Late nights I guess.
