    摘要： A light control sheet including a first transparent electrode layer, a second transparent electrode layer, a light control layer including a resin layer which is formed between the first and second transparent electrode layers and includes a liquid crystal composition in holes formed in the resin layer, the liquid crystal composition including liquid crystal molecules, and a first alignment layer formed between the first transparent electrode layer and the light control layer such that a haze of the light control layer is increased upon application of a voltage to the first transparent electrode layer. The light control layer includes a first high-density portion and a low-density portion, and the first high-density portion is in contact with the first alignment layer and includes the liquid crystal composition at a density higher than a density of the liquid crystal composition in the low-density portion per unit thickness of the light control layer.

    摘要： A method of manufacturing a segmented electro-optic display includes providing an electro-optic display stack including a first substrate layer, a first layer of light-transmissive electrically-conductive material, a layer of electro-optic material, a lamination adhesive, a second layer of light-transmissive electrically-conductive material, and a second substrate layer. The method also includes forming electrically-isolated conductive segments on the second layer of electrically-conductive material using a laser etching process that includes irradiating the second substrate and second electrically-conductive layers at multiple locations with a laser emitting light within a first range of wavelengths. The second substrate layer is transmissive of light within the first range of wavelengths, and the light-transmissive electrically-conductive material is substantially absorptive of light within the first range of wavelengths. At each of the multiple locations, the second substrate layer substantially transmits the light emitted from the laser and the light-transmissive electrically-conductive material substantially absorbs the light and is removed.
