Esquire E-Ink analysis

This is part of my attempt to directly drive the E-Ink displays that came with the October 2008 Esquire magazine.

I hooked up 2 of the 4 pins that go to the car ad display to my oscilloscope. They are designated based on the resistors that are connected to them (R25 and R26). R27 and R28 seem to have the same pattern as R26, so those represent the individual segments. R25 seems to affect them all, as when it goes high (to +15vDC), one of the the display segments goes white.
