Methods for driving electro-optic displays

Abstract

Methods and apparatuses are provided for driving electro-optic displays, particularly electrophoretic displays, to enable rapid image transfer for animation and video applications. These methods address the technical problem of transfer bottlenecks by remapping 8-bit pixel data (Y8) to reduced-bit formats (Y1 or Y2) prior to transfer, thereby significantly reducing data size and transfer time. The method also describes multiple formats for organizing the pixel data into data packets. Such remapped data may be expanded back to Y8 format within the display controller for subsequent processing and presentation. Because the data is reduced before transmission, the system enables efficient animation and video playback on high-resolution electrophoretic displays, ensuring smooth sequential content updates without overwhelming the available data links.
