A request to identify the display.

I got a "third-hand" display, with no indication of what he was or whether it was efficient, what power supply, what order of connecting the pins. Therefore, I am asking those who have knowledge about this display for help in how to check it, and in particular what type it is, how to power it, how to connect pins. Looking from the back of the display (photo 3) with the systems, the systems from the top are not marked (there are four), from the bottom the chip most left (closest to the pins) is an 8-pin system marked 5310, then three circuits OKI Japan M5839B, and the last chip is OKI Japan M5238. The display board has dimensions of about 180mm by 75mm, with the screen itself measuring 130mm by 40mm, connecting pins 10 on the left, and 2 on the right (they look like connection to the backlight). Once again, I am asking for help in checking those who have such knowledge. Greetings!

I had and used a display with 10 pins.
The first six were typical of the popular hd47780 displays: gnd, vcc, contrast, rs, rw, e.
The others were d4, d5, d6, d7.
In your appearance pin3 is connected to the metal frame of the display, so it will be rather gnd and not contrast, the other two pins are probably highlighting, which can be easily checked.

Hello! Thank you for your interest, but after a few attempts with different configurations, I could not display anything, even the cursor, but I tested it on Atmedze8 giving the tested program and various earlier checked versions of the display from 16x1 and beyond. So, for now, I leave him with the hope that I will try again. Greetings.
