Datasheet for the PE12864-001 LCD module, supplied as a 249 KB PDF. The 12864 in the part number conventionally indicates a 128 x 64 dot graphic display, a very common size in instruments and industrial controls. Expect electrical characteristics, pin descriptions, the controller command interface, timing diagrams and outline dimensions. It is useful for checking supply and negative bias voltages when a screen shows no contrast, or for wiring a replacement. Match the -001 revision code against the label on the actual part before relying on it.
