Word document of about 1008 KB covering the PG640480FRT-ANN-I display, a 640 by 480 graphic LCD module per its numeric code. It appears to be the editable source of the specification also available as a PDF, so content should include pin assignments, electrical characteristics, timing and dimensions. Open it with Microsoft Word or LibreOffice; older .doc formatting may shift slightly. Compare against the PDF edition if figures look inconsistent, and confirm the module label before using it for repair.
