it is 10 pin on left edge and 6 pin on right edge...Yup it is display on the LED pcb.
Any have idea when i running 4digit 7-segment on proteus, its display constant value, but after i replace it with single 7-segment its display in blinking..i am getting blur right now.
I think my 7-segment is same as yours...i dont have any reference about the pin, do you have datasheet..or can you tell me which pin is a thru g, decimal point pin, and how to know weather its ca or cc??

hi toofast,
My pins are along the bottom edge of my pcb, its not the same layout as yours.
As I said the only way if you cannot get the datasheet for yours, is to use a 330R resisitor and keep connecting the pins until you work out which pins are which.
I use multimeter as a source about 4.13V, not on ohm, yup my meter have diode test function...i also have tried on single 7-segment. I realized that my 4digit 7-segment is quite weird, it has 16 pin bottom the edge, from left i assume pin 1, pin 1 and pin 2 function to activate the 7-segment and the rest is for display, the pin is not arrange properly..

hi,
All the LED panels I have seen are never connect 1,2 3 etc,
If you use a supply of about +5V and a 330R resistor, by using a wire link to 0V on a pin and connecting another pin to +5V via the 330R a LED segement may light up.
Keep changing the wire link and resistor pin, IF its a standard LED panel eventually you should be able to work it out.
Its not easy, but I dont know another way if you have no datasheet.
