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.
