  • Publication number: 20240086021
    Abstract: A substrate assembly is provided, including a first substrate, an active element layer, a plurality of first electrodes, a circuit substrate, and a plurality of second electrodes. The active element layer is disposed on the first substrate. The plurality of first electrodes are disposed on the first substrate and arranged along a first direction. The circuit substrate is partially overlapping the first substrate in a vertical projection direction. The plurality of second electrodes are disposed on the circuit substrate. A distance between the edge of one of the plurality of second electrodes and the edge of one of the plurality of first electrodes is greater than zero in the first direction, and a width of the one of the plurality of first electrodes is different from a width of the one of the plurality of second electrodes.

  • Patent number: 11657773
    Abstract: A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include (a) applying a first drive scheme to a non-zero minor proportion of the pixels of the display and a second drive scheme to the remaining pixels, the pixels using the first drive scheme being changed at each transition; (b) using two different drive schemes on different groups of pixels so that pixels in differing groups undergoing the same transition will not experience the same waveform; (c) applying either a balanced pulse pair or a top-off pulse to a pixel undergoing a white-to-white transition and lying adjacent a pixel undergoing a visible transition; (d) driving extra pixels where the boundary between a driven and undriven area would otherwise fall along a straight line; and (e) driving a display with both DC balanced and DC imbalanced drive schemes, maintaining an impulse bank value for the DC imbalance and modifying transitions to reduce the impulse bank value.

  • Patent number: 8125501
    Abstract: A method and system for applying addressing voltages to pixels of a display involves receiving input data. The input data includes an indication of an addressing voltage impulse to be applied to a pixel via an electrode. One or more voltage sources are selected, to provide the addressing voltage impulse. The one or more voltage sources each have a pre-selected voltage, The selected one or more voltage sources are electrically connected to an electrode to apply the addressing voltage impulse to the pixel. The invention also provides a method of driving an electro-optic display which uses an intermediate image of reduced bit depth, and a method of driving an electro-optic display which uses a limited number of differing drive voltages, with higher voltage pulses being used before lower voltage pulses.
