    Abstract: A printer for printing to electrically printable media is described. During printing, a drum surface having first and second portions is charged to a first voltage, and the second portions of the surface are selectively discharged. A transfer electrode has a uniform voltage applied thereon. A first erase electrode and a second erase electrode have a fixed voltage differential between them. The printer receives the electrically printable medium between the first erase electrode and the second erase electrode to expose the electrically printable medium to the fixed voltage differential, and to move the electrically printable medium proximal to the drum and the transfer electrode to expose the electrically printable medium to a first voltage differential that results from the first voltage of the first portions and the uniform voltage, and a second voltage differential that results from the second voltage of the second portions and the uniform voltage.

    Abstract: Devices, systems, and methods are provided for generating a wide angle frontlight for use with reflective displays. A display device may include a first end and a second end opposite the first end, and a first side and a second side opposite the first side. The display device may include a first light source, and a first light guide able to receive first light from the first light source. The display device may include a reflective display, the first light guide including a first refractive device, the first refractive device refracts a first portion of the first light toward the reflective display in a first direction toward the first side and to refract a second portion of the first light toward the reflective display in a second direction toward the second side, and the first direction separated from the second direction by a first angle of at least forty degrees.

    Abstract: Described herein are electrically printable media. The electrically printable medium includes a first flexible structural layer, a second flexible structural layer, and an electronic ink layer comprising a plurality of cells that include charged particles in a fluid. The electronic ink layer is disposed above the first flexible structural layer. The second flexible structural layer is disposed over the electronic ink layer. The electrically printable medium is adapted to have content rendered visible thereon based on electrical signals supplied by a printer.

    Abstract: This application describes techniques for erasing (e.g., smudging, rendering illegible, etc.) images that are presented on display mediums, such as electronic-paper displays. Electronic-paper displays include a layer of electronic ink comprising charged particles suspended in a fluid. When a voltage differential is created across the reading surface, the charged colored particles may rise to the reading surface, retreat to the opposite surface, or suspend somewhere there between, thereby creating a visible image. In some instances described herein, a common electrode is partitioned into at least two sets of elements interleaved with one another. To erase an image, a voltage differential may be driven between these two sets of elements, creating an in-plane electrical field that erases the image.

    Abstract: The subject matter disclosed herein relates to an electrowetting display comprising pixels that include colored subpixels that comprise: a colored reflective layer on a support plate; an electrode; a hydrophobic layer; and a liquid region including an electrolyte, and dark electrowetting oil and white electrowetting oil both being immiscible with the electrolyte. A coverage area of the dark electrowetting oil on the hydrophobic layer and a coverage area of the white electrowetting oil on the hydrophobic layer are individually electronically adjustable to affect light transmission to the colored reflective material.
