Short 95.2 KB PDF datasheet for the PG9832 family, revision letter A, without a specific variant suffix in the name. The base number most likely corresponds to a 98 by 32 dot monochrome graphic LCD. A generic family sheet like this usually covers the common pinout, interface timing, electrical limits and outline shared by all variants. Repair staff can rely on it for basic signal tracing, but backlight type and temperature grade depend on the full ordering code, so cross-check with a variant sheet if available.
