Abstract:
A method for rendering drawing events on an electro-optic display such that a stylus (pen) stroke is perceived as actually writing on the electro-optic display. Typically, a first line segment is detected and its area is updated using a first drive scheme having faster waveforms. Then a second line segment is detected and its area is updated using the first drive scheme. Thereafter, the areas of both line segments are updated using a second drive scheme different from the first drive scheme, typically involving slower waveforms.

Claim (Index 1):
A method for driving an electrophoretic display including an electrophoretic medium comprising a black pigment, pixels defined by pixel electrodes, and a digitizing layer configured to sense the position of a stylus with respect to the electrophoretic display, the method comprising:\n detecting a first line segment drawn on the electrophoretic display with the stylus; rendering the first line segment in low contrast by driving black pigment toward a viewing surface adjacent pixel electrodes corresponding to the first line segment using a first drive scheme, the first drive scheme including waveform impulses smaller than an impulse needed to achieve an extreme black state in the electrophoretic medium; detecting a second line segment drawn on the electro-optic display with the stylus; rendering the second line segment in low contrast by driving black pigment toward a viewing surface adjacent pixel electrodes corresponding to the second line segment using the first drive scheme; and after both the first and second line segments have been rendered in low contrast using the first drive scheme, rendering both the first line segment and the second line segment using a second drive scheme different from the first drive scheme, wherein the second drive scheme includes impulses sufficient to drive black pigment to the extreme black state in the electrophoretic medium.
