First section, labelled P1, of the PE160160BRF-001H module datasheet, saved as a 431 KB PDF. The numbering points to a 160 x 160 dot graphic LCD, with the matching P2 file completing the document. Opening pages usually cover general specifications, absolute maximum ratings, pin description and electrical characteristics. That makes it the right starting point to identify supply pins and voltage limits before probing a dead display or connecting a replacement module.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @acodis_lcd_datasheets_EDID. Enginerys does not host this file.
