I have no idea whether the graphic panels use the same nibble interface that the character displays do, but I'm guessing the interface could be quite different. I'm actually the one who explained the character corruption issue we can get on the 20x4 displays, but it's not related to the OP's display issue. FWIW, the thread where I discuss the 20x4 screen corruption problem is in the firmware enhancements to marlin area - http://3dprintboard.com/showthread.p...ed-LCD-screens
OK! Sorry to interrupt! Thank You for the explanation!
