I’m working on repackaging a framework mainboard in a different case and I needed a smaller display panel to make everything work. The iPad 7 panel is the perfect size, but there was essentially zero information out there on the electrical interface.
I spent a little bit of time reverse engineering the pinout and designed an adapter board that “bridges the gap.” The DisplayPort lanes are connected straight through, but the backlight arrangement is completely different, so my board also has a boost converter to power the backlight.
Pretty happy with the result. The panel just works now and doesn’t require any fiddling with resolution settings. I plan on posting all the design files once I get the main project to a more complete state.
