Abstract
Official abstract text for this publication.
An electronic device may have a liquid crystal display having a backlight and color mixing prevention structures. The color mixing prevention structures may, in part, be formed from one or more arrays of color filter elements. The liquid crystal display may include first and second transparent substrate layers on opposing sides of a liquid crystal layer. The display may include a first array of color filter elements on the first transparent substrate layer and a second array of color filter elements on the second transparent substrate layer. One or more of the arrays of color filter elements may include a black matrix formed over portions of the color filter elements. The color filter elements may fill or partially fill openings in the black matrix. The display may include a collimating layer on the second transparent substrate layer. The color filter elements may include cholesteric color filter elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A display, comprising: a first transparent substrate layer; a second transparent substrate layer; a layer of liquid crystal material formed between the first and second transparent substrate layers; a first color filter layer formed on the first transparent substrate layer; a second color filter layer formed on the second transparent substrate layer, wherein the first color filter layer comprises a first array of color filter elements and a first bla…
