Abstract

A method is described for driving an electro-optic display having a plurality of display pixels. The method includes updating the electro-optic display with a first image including image data from a first portion of a scrollable content. The method also includes receiving a user input comprising one or more parameters, and generating a second image based on at least one parameter of the user input. The second image includes: a subset of the image data from the first portion of the scrollable content, and image data from a second portion of the scrollable content. The method also includes updating the electro-optic display with the second image.

Claims (19)

1 . A method for driving an electro-optic display having a plurality of display pixels, the method comprising:

updating the electro-optic display with a first image comprising image data;

receiving a user input comprising one or more parameters;

generating a second image based on at least one parameter of the user input, wherein the second image comprises a subset of the image data of the first image but is enlarged to have dimensions equal to the first image;

separating the second image into a plurality of portions of the second image;

updating the electro-optic display with a first portion of the plurality of portions of the second image;

updating the electro-optic display with a second portion of the plurality of portions of the second image, wherein the second portion does not include the content of the first portion.

2 . The method of claim 1 further comprising:

performing a time delay subsequent to updating the electro-optic display with the first portion of the plurality of portions of the second image, wherein updating of the electro-optic display is suspended during the time delay, and wherein the electro-optic display is updated with the second portion of the plurality of portions of the second image

subsequent to the time delay.

3 . The method of claim 2 further comprising applying an edge clearing waveform to the display pixels of the electro-optic display during the time delay.

4 . The method of claim 2 further comprising:

identifying display pixels with edge artifacts using an algorithm configured to flag a display pixel for having edge artifacts based on the display pixel's next optical state and the optical state of at least one of the display pixel's cardinal neighbors; and

applying an edge clearing waveform during the time delay to the display pixels flagged by the algorithm.

5 . The method of claim 2 wherein the second portion of the plurality of portions of the second image surrounds the first portion of the plurality of portions of the second image.

6 . The method of claim 1 wherein the user input comprises a pinch-out zoom gesture on the electro-optic display.

7 . The method of claim 6 wherein the user input comprises a parameter indicating a magnitude of a linear distance of the pinch-out zoom gesture.

8 . The method of claim 7 wherein an amount the subset of the image data of the first image is enlarged in the second image is proportional to the magnitude of the linear distance of the pinch-out zoom gesture.

9 . The method of claim 7 wherein a position of the first portion of the plurality of portions of the second image is based on an initial point of contact of the pinch-out zoom gesture.
