If it's a German design manufactured in China the pin describtions were obviously misprinted. They should be -K and +A.
The backlights of LC-displays vary in current flow (commonly 50mA). Use 100Ohms in series and connect to VCC and GND. If connected reversely the display stays dark, the other way it will light.
The pin numbers , though 1 to 14 or 1 to 16, are not in the same order in few makes of LCDs. I saw one unit by M/s XIAMEN OCULAR model GDM1602M, where in the pins are on the top right instead of standard TOP left and the order is 16, 15, 1, 2,...... 14.
@ Sivaram... please re-check the definitions of pins 15 and 16.
i got the same lcd recently and am trying to use it to display liquid level but i want full description on the function of the pins and the order of pin arrangements(i.e. from what point should i start counting the pins). i also want to know the functions of the four pins by the left u can see them in the attachment
