Can someone help me understand (1) What is this screen/display called, (2) How could I use a screen type like this as an output from a computer (#Linux, #RaspberryPi), (3) What's the current "state of the art" of this screen tech, given TI-92 is older tech, (4) What could help make this more readable in direct sun? (5) Who's straight-up just used a Ti-92 as a "typewriter / IDE on-the-go" and how did that go?

Mission: A5-sized, Sun-friendly #OpenSource typing/programming tool
