Claim Text:
1. A method of driving an electro-optic display having a display surface, the method comprising: detecting a touch upon the display surface: driving a portion of the electro-optic display surrounding the touch from its previous optical state to a different optical state; and automatically driving the portion of the electro-optic display surrounding the touch from the different optical state to its previous optical state, wherein an overall drive scheme for driving the portion of the electro-optic display surrounding the touch from its previous optical state to the different optical state and back to its previous optical state is direct current (DC) balanced, wherein the overall drive scheme for driving the portion of the electro-optic display surrounding the touch from its previous optical state to the different optical state and back to its previous optical state is between 60 milliseconds (ms) and 250 ms in total length, and wherein the electro-optic display comprises an electrophoretic material comprising a plurality of electrically charged particles disposed in a fluid and capable of moving through the fluid under the influence of an electric field.
