Brief PDF of about 60 KB documenting the PG320240-D display module, one of the lettered variants of a 320 x 240 dot graphic LCD series. Being small, it probably focuses on essentials such as pinout, supply limits and an outline drawing rather than full command tables. Use it for quick identification of the connector and power pins when diagnosing a blank screen, and check dimensions and mounting holes before substituting another variant of the same series.
