  • Writing to an electronic imaging substate
    Patent number: 10000074
    Abstract: A method for writing to an electronic imaging substrate includes passing an electronic imaging substrate in relation to a writing device to change a state of image cells within the electronic imaging substrate. The imaging substrate is placed close enough to the writing device to reduce a blooming effect to a predefined threshold level when changing a state of one of the image cells within the electronic imaging substrate.
