Some Question

I should also mention that I want to save animated eyes so that you can see the eyelids opening and closing.

As long as there are enough GPIOs to separately control two independent displays, a single control board can be used to control the displays.

ok,thanks for the answer

That's an interesting project! Thinking about rotating those displays makes me feel like I'm strategizing in Bitlife , carefully planning my character's life choices. It sounds like you need a flexible control system. While I'm not an expert on display hardware, I'd guess that whether you can control both with one board depends on its capabilities. Check the specs or maybe ask in a hardware-focused forum.  

I love how creative this setup sounds. If you’re aiming to use two displays as eyes, you could rotate them 90 degrees (one each way) and connect them to a single control board or use separate boards, depending on your wiring and power needs. It’s worth checking if both displays can be driven by the same controller or if you’ll need charm with a Raspberry Pi Pico or similar. By the way, Drive Mad is a cool example of quirky DIY spirit.

I once wrestled with getting multiple small screens to display a panoramic image for an art installation. The synchronization was a nightmare! Imagine Slither io but on multiple screens, needing seamless movement. We eventually cracked it with a Raspberry Pi and some custom coding, but it was a journey.
