The display has a main connector used to provide all of the controls. 

The nomenclature is a bit tangled, but the basic idea is that every color (RGB) is addressed by one set of nine TLC5941 drivers. Each of those sets is clocked and blanked together, but broken into three sub-banks for data input. 

I believe the path to effective operation is using an MCU with at least three QSPI busses. I have an ESP32-WROOM-32D breakout on hand to test with, but I'm going to make a PCB to interface with the display. 

I'm feeling pretty positive about the way this is coming together. Using the ESP, I can set this display up to be controlled via network. The only connection needed is a power supply.
