PDF datasheet, 165 KB, for the PG12232LRU-CNN-B graphic LCD module. The letters after the base number usually mark build options like backlight type, polarizer mode and operating temperature, so this sheet targets that specific combination. Expect pin descriptions, dimensions, electrical characteristics and bus timing diagrams. Repair work typically involves confirming LCD bias and logic supply pins, tracing the data bus to the host board, and selecting an equivalent part; check that the label code on the module matches before relying on it.
