Abstract
A touch screen electro-optic display is arranged such that upon a touch being detected on the display surface, the display surface surrounding the touch 'blinks' by being driven to a different optical state, then back to its original state. A second method uses a display having a pen or stylus which can draw lines upon the display. A first line segment is detected and its area updated using a first drive scheme having short waveforms. The area of a second line segment 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.
