PG12864ERS-INN-H is the module documented in this 225 KB PDF datasheet, a configuration of the 128 by 64 dot PG12864 graphic LCD. The ERS series code and INN-H suffix identify the exact build, which the ordering information should break down. Inside are pin functions, supply and drive voltage specifications, backlight data, timing and outline dimensions. Use it to diagnose display faults on control panels and to check compatibility of a replacement, verifying the entire code printed on the module rather than only the base number.
