PDF spec sheet for the PG9732LRS-CE3-H graphic LCD module, 162 KB. The base number points to a 97 by 32 dot matrix panel, and LRS-CE3-H selects a specific combination of options described in the ordering information. The file is a reference for pinout, logic and drive voltages, interface timing and outline drawing. When a display fails, a technician can measure supply and contrast rails against the listed values, but should confirm the module marking matches this variant before drawing conclusions.
