PDF datasheet, 1.86 MB, for the UG-2828GFEAF01 display module, with SAS1-D001-A in the name likely being a document control number and revision A. It differs in code from the GCEAF02 sheets in this collection, so treat it as a separate variant. Expect pinout, electrical ratings, power sequencing and outline drawing. Use it to verify rails on the module connector and wiring for a replacement, and confirm the module label matches this exact code since interface options may differ.
