Abstract: A hybrid display including an emissive display adjacent a variable transmission display. The hybrid display device typically includes a controller. The emissive display provides an image that is viewable from a viewing location, and the variable transmission medium is positioned relative to the emissive display to partially alter the image at the viewing location. The controller generates a desired altered image at the viewing location by controlling the electrophoretic image display or the variable transmission medium. The display device can include an ambient light sensor. The hybrid display can be incorporated into a combination display by combining the hybrid display with one or more additional electrophoretic displays.

Abstract: A color electro-optic display includes a layer of electro-optic material having a light-transmissive electrode on a viewing side, an array of pixel electrodes on an opposite side, and a color filter array (CFA) on the viewing side. The pixel electrodes drive selected portions of the electro-optic material between white and black optical states. The CFA includes an array of pixels, each of which has at least three color filter elements. Each color filter element is aligned with a different one of the pixel electrodes such that the color of any color filter element is visible when the adjacent portion of the electro-optic material is driven to the white optical state, and not visible when driven to the black optical state. The colors of the color filter elements have the same lightness or a lightness difference no greater than 10 L* to substantially eliminate visible CFA texture patterns in displayed images.
