Abstract: A method for driving electro-optic displays including a layer of electro-optic material disposed between a common electrode and a backplane including an array of pixel electrodes, each coupled to a pixel transistor. The method for driving includes apportioning a displayable region of the electro-optic display into N BRAID line groups, where each of the N BRAID line groups is associated with a frame buffer. The method also includes receiving first image data comprising optical state data for the entire displayable region of the electro-optic display, and sequentially writing subsets of the first image data to each of the N frame buffers, wherein each of the N frame buffers is written with data corresponding to the corresponding BRAID line group. The method also includes sequentially updating portions of the displayable region of the electro-optic display based on the data in each of the N frame buffers.

Abstract: The present invention provides four-particle electrophoretic displays with improved driving methods to achieve better color separation between adjacent pixel electrodes. The driving methods improve the color state performance when a first pixel is displaying a mixed state of a first highly-charged particle and a second lower-charged particle of the opposite polarity, while a neighboring pixel is displaying a state of a second highly-charged particle having the opposite polarity to the first highly-charged particle. The particles can be, for example, all reflective or one type of particle can be partially light transmissive.

Abstract: Methods for driving an electrophoretic medium including two pairs of oppositely charged particles. The first pair including a first type of positive particles and a first type of negative particles and the second pair consists of a second type of positive particles and a second type of negative particles, wherein the first pair of particles and the second pair of particles have different charge magnitudes (identifiable as zeta potentials). In particular, the driving methods produce cleaner optical stakes of the lesser-charged particles with less contamination from the other particles and more consistent electro-optical performance when the intermediate driving voltages are modified.
