  • Publication number: 20260120656
    Abstract: Methods 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.

  • Patent number: 12603063
    Abstract: A color electrophoretic display that includes sets of duplicative waveforms to reduce visible artifacts during image updates. Such methods include driving extra pixels where the boundary between a driven and undriven area would otherwise lead to artifact by providing paired sets of driving instructions, allowing the undriven area to be driven while maintain the desired (undriven) optical state.

  • Patent number: 11557260
    Abstract: A method for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include driving extra pixels where the boundary between a driven and undriven area would otherwise lead to artifact by providing paired sets of driving instructions, allowing the undriven area to be driven while maintain the desired (undriven) optical state.
