Starting with LCDs, it's not so much a question of display, but rather
of data transmission between computer and display. It's the tradition of
transmitting the whole image N times per second that leaves LC displays
still prone to such types of attacks.
With e-paper, it would appear prudent to transmit only changes in the
image buffer (so that an eavesdropper couldn't afford to miss a single
bit), but it is yet to be seen whether this will happen. After all, even
with contemporary displays it would appear to me much more efficient to
transmit only the delta of information, at least for everyday office use.
