Graphic LCD module datasheet for the PG12864-H, supplied as a 105 KB PDF. The H variant belongs to the 128 by 64 dot PG12864 range, and the document should give the connector pinout, voltage and current ratings, interface timing and a dimensional drawing. Repair technicians use it when a display shows faint, missing or garbled content, to verify supplies and control signals and to select a suitable replacement. Make sure the module in hand carries the H suffix before applying these specifications.
