27. A system for digitizing data written to an electronic ink display, comprising:
-
an electronic ink display that includes an array of display elements in which a plurality of charged pigmented particles are suspended in a dielectric medium, the array of display elements interposed between a common electrode and a grid of addressable electrode elements;
a hand-held charged device to effect display state modifications in one or more display elements of the electronic ink display;
a memory to store display data representing display states for the display elements of the electronic ink display;
a display driver operatively connected between the memory and the grid of addressable electrode elements to set display states of at least one display element of the electronic ink display based on the display data; and
an identification and detection circuit operatively connected to the electronic ink display to determine the display state of the at least one display element of the electronic ink display. - View Dependent Claims (28, 29)

30. A program comprising a storage medium tangibly embodying program instructions for digitizing data written to an electronic ink display, the program instructions including instructions operable to cause at least one programmable processor to:
-
set an element of the electronic ink display array to one of a plurality of persistent display states based on display data in memory;
wait in a power down or power off mode of operation for a signal to initiate a read operation;
read the element to determine the display state; and
store data for the display state read in the memory. - View Dependent Claims (31, 32, 33, 34)
