Abstract
This invention provides methods of and related apparatus for driving an electro-optic display having a plurality of pixels. The method includes dividing the plurality of pixels into n groups, where n is an integer larger than 1, applying a full clearing waveform to at least one group of the n groups of pixels, and applying a top off waveform to cardinal pixels of the at least one group of pixels.

A method for driving an electro-optic display having a plurality of pixels, the method comprising:
- dividing the plurality of pixels into n groups, the plurality of pixels configured to display white text on a black background, and wherein n is an integer larger than 1;
- applying a full clearing waveform to at least one group of the n groups of pixels;
- and
- subsequently, apply a top off waveform to cardinal pixels of the at least one group of pixels.
A method for driving an electro-optic display having a plurality of pixels, the method comprising:
- dividing the plurality of pixels into n groups, the plurality of pixels configured to display white text on a black background, and wherein n is an integer larger than 1;
- and
- applying a top off waveform to at least one group of the n groups of pixels.
A method for driving an electro-optic display having a plurality of pixels, the method comprising:
- applying a DC-imbalanced full clearing waveform to a non-zero minor proportion of the plurality of pixels, the plurality of pixels configured to display white text on a black background;
- and
- applying a DC-imbalanced top off waveform to cardinal pixels of the non-zero minor proportion of the plurality of pixels.
A method for driving an electro-optic display having a plurality of pixels, the method comprising:
- applying a DC-imbalanced top-off waveform to a non-zero minor proportion of the plurality of pixels, the plurality of pixels configured to display white text on a black background;
- and
- applying the DC-imbalanced top-off waveform to a different non-zero minor proportion of the plurality of pixels.
