AUO panel specification for the G150XG02, version V0, in a 660 KB PDF filed as a schematic. AU Optronics G-series parts are industrial LCD modules, and a spec like this normally lists the interface connector pinout, input voltage, signal timing and backlight details. Technicians use it to check the LVDS connection, supply rail and backlight driver requirements, or to find a compatible replacement. Make sure the label on the panel matches G150XG02 and the version before trusting pin data, as later revisions can differ.
