Datasheet for the PG320240-F graphic display, a small 83 KB PDF covering this lettered variant of the 320 x 240 dot module range. The content is likely limited to the core tables: pin assignment, supply ratings, interface timing and outline drawing. When a device using this panel shows a blank or faded screen, use the sheet to locate logic and contrast supply pins and measure them. Compare the F variant against others before swapping, since letters may mark different controllers or dimensions.
