1.54 e-ink without driver
Kind of yes and kind of no.

It requires external circuitry, but that circuitry isn't a "driver board" in the traditional sense.

An e-Ink display requires high voltages to charge the electrostatic cells. Traditionally that would be provided using an external "driver" circuit - a boost voltage converter.

However this display has that boost converter built in - though it doesn't have all the components, because they just won't fit.

You need to provide the diodes, switching MOSFET, and inductor, etc as shown on page 18 of the datasheet.  Nothing less will do.
