Abstract: An electronic display comprises an array of pixels each comprising first, second, and third primary light-emitting elements that emit primary colors at first, second, and third physical primary color points on a chromaticity diagram, and one or more derivative light-emitting elements that each emit a derivative color at a derivative color point on the chromaticity diagram. The physical primary color points and each derivative color point are located on a boundary of a virtual color space that includes first, second, and third apexes at first, second, and third virtual primary color points on the chromaticity diagram. At least one of the first, second, and third virtual primary color points is different from the first, second, and third physical primary color points, respectively. A color gamut for the pixels is greater than a corresponding gamut for corresponding pixels that are configured to only emit the primary colors.

Abstract: A separator for a lithium battery is a coating of an inorganic oxide (for example, aluminum oxide) and an organic polymer (for example, polyvinylidene difluoride (PVdF)). In a method, the separator is formed on an electrode material layer (for example, graphite) of an anode electrode. In a first pre-wetting step, a first liquid comprising a first volatile liquid is applied to the electrode material such that pores in the material are filled. In a second step, a second liquid is applied over the first liquid. The second liquid includes inorganic oxide particles and the organic polymer dispersed in a second volatile liquid. The first and second volatile liquids are then substantially removed (for example, by evaporation in a drying oven) thereby leaving the separator coating on the electrode material of the anode, and leaving the pores filled with a gel or solid electrolytic polymer material.
