Datasheet in PDF form for the PG12032 module, revision letter D, a 76.7 KB document. The numeric part of the code most likely denotes a 120 by 32 dot graphic LCD, a naming style used by Powertip for its monochrome panels. Expect pin assignments, controller interface timing, supply voltages and outline dimensions. Technicians use it to identify connector pinout and check contrast or backlight supply when a display stays blank, but confirm the full part code printed on the module before trusting values.
