Waveshare AMOLED
From dankwiki
I am using a 5.5" Waveshare AMOLED capacitive screen in my workstation, together with a Raspberry Pi 3B. They are powered over USB from Molex, and receive data using IP-over-USB together with an internal USB3 header. It's a great little device at a good price point (about $130), though quite fragile.
The Waveshare wiki page for the device is a good place to start.
