The large digits really got me excited but Googling the part number KEM-18011-BSR-2L did not yield a lot of information. But the lack of a decimal point suggested the standard pinout mapping did not apply. So I took a 5V power supply, some DuPont cables and a 330 Ohm current limiting resistor and started prodding the pins. Nothing happened. I wondered if it could be a common anode display, switched polarity of my wiring and bingo!
I managed to work out the LCD pinout and it goes like this:
Note that pin 8 is not used; this is where the missing DP segment would have connected.
