Abstract
Official abstract text for this publication.
A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods includes updating a display having a plurality of display pixels with a first image, identifying display pixels with edge artifacts after the first image update, and storing the identified display pixels information in a memory.
First claim
Opening claim text (preview).
1 . A method for driving an electro-optic display having a plurality of display pixels comprising: updating the display with a first image; identifying display pixels with edge artifacts after the first image update; and storing the identified display pixels information in a memory. 1 . The method of claim 1 , wherein the step of identifying display pixels with edge artifacts comprising determining the graytone transitions of the display pixels. 2 . The method of claim 1 , wherein the step of identifying display pixels with edge artifacts comprising determining displays pixels having different graytones than at least one of its cardinal neighboring pixels. 3 . The method of claim 1 , wherein the step of identifying display pixels with edge artifacts comprising flagging the identified pixels to a memory associated with the display's controller. 4 . The method of claim 1 , further comprising applying a waveform to the display pixels identified with edge artifacts. 5 . The method of claim 5 , wherein the waveform is substantially DC balanced. 6 . The method of claim 5 , wherein the waveform is DC imbalanced. 7 . The method of claim 6 further comprising performing a post drive discharge. 8 . The method of claim 1 , wherein the step of storing the identified display pixels in a memory comprising storing the identified display pixels information in a binary map.
