Specification document for the PG240160BRF-BNN-H graphic display, a 142 KB PDF whose name also carries an OK mark, presumably noting a checked or approved copy. The part code indicates a 240 x 160 dot LCD module, with the suffix letters selecting backlight, viewing and temperature options plus revision H. Use the sheet for the connector pinout, logic and LCD drive voltages, interface timing and dimensional drawing during repair or replacement. Compare the code on the module itself, since neighbouring variants may differ electrically.
