So far, I have cut away the back aly body, and exposed the driver boards, with hardly any damage.
It looks like there are a bunch of driver IC's attached to the drivers, under what at first looked like kapton tape, but now appears to be some sort of flexi-circuit taking the oled drive to the front of the screen. See pic of one partly peeled up.
One idea I had was to power it up (see below*) and strap strong LEDs to the driver chips, which might activate the drivers, and as I switch the LEDs it will switch the drivers on and off, in unpredictable ways.
* I need to identify the power rails and what the rail voltages are. GND is easy.
If you know what the OLED drive voltages might be for R, G and B that would be interesting.
It's an HD display so ~1000x720x3? But I count only around 600? lines to the front through the flexis. So it's still a mystery how the individual LED's are addressed/powered.

So I've been taking a closer look at some of this today. It seems that the bare silicon chips attached to the flexi circuits are some sort of decoder/driver, and probably fan out even further to the thousands of LEDs on the front of the panel. It looks like there's a bussed digital interface to these chips that traverses the driver PCB's. So to make anything happen, I'm still at the level of a digital interface to poke data at the driver chips, and not at the "LED Matrix" level.
