    摘要： Methods and apparatus for an electrophoretic display in which the particle motion is a controlled, non-linear function of the applied electric field. Threshold addressing allows simple, inexpensive passive addressing techniques to be employed. The inverse electrorheological gating techniques allow the construction of a full color, passively addressed display without the need to address individual capsules. A mixture of capsules is coated randomly onto a substrate enabling the creation of inexpensive displays. All the techniques allow a significant threshold to be realized. Rapid movement of the pigment particles above the threshold allows rapid switching times for the display. Since diffusion and gravity are extremely weak forces compared to the yield stresses created, the structured or gelled medium approach provides a great improvement in the bistability of the displays.

    摘要： A coating of an encapsulated electrophoretic medium is formed on a substrate (106) by dispersing in a fluid (104) a plurality of electrophoretic capsules (102), contacting at least a portion of a substrate (106) with the fluid (104); and applying a potential difference between at least a part of the portion of the substrate (106) contacting the fluid (104) and a counter-electrode (110) in electrical contact with the fluid (104), thereby causing capsules (102) to be deposited upon at least part of the portion of the substrate (106) contacting the fluid (102). Patterned coatings of capsules containing different colors may be deposited in registration with electrodes using multiple capsule deposition steps. Alternatively, a patterned coating may be deposited upon a substrate containing a conductive layer by varying the conductivity of the conductive layer by radiation exposure or by coating portions of the conductive layer with an insulating layer, typically a photoresist.

    摘要： The invention features a photoconductively addressed display and a method of photoconductive addressing in a display. The method includes providing an electro-optic imaging layer that extends in an X direction and a Y direction and comprises an array of image elements. A column electrode layer is provided adjacent to one side of the electro-optic imaging layer. The column electrode layer includes a plurality of column electrodes that each extend in the Y direction and are spaced from one another in the X direction. A photoconductive layer disposed between the electro-optic imaging layer and the column electrode layer is provided. An elongate portion of the photoconductive layer is illuminated in the X direction while scanning the illumination in the Y direction to translate a location of the illuminated elongate portion. At least one image element of the array of image elements is addressed by applying an intermittent voltage to one of the plurality of column electrodes that is adjacent to the at least one image element while the illuminated elongate portion of the photoconductive layer is adjacent to the at least one image element.

    摘要： An electrophoretic display has a viewing surface, and includes an image pixel. The image pixel includes a first plurality of particles having a first mobility, and a second plurality of particles having a second mobility. At a first addressing voltage, the first mobility is greater than the second mobility. At a second addressing voltage, the second mobility is greater than the first mobility. At least one of the first and second mobilities is a variable function of voltage, i.e., a function of an applied electric field. Application of the first addressing voltage produces a first optical state, which is determined by a motion of the first plurality of particles. Application of the second addressing voltage produces a second optical state determined by a motion of the second plurality of particles.
