Abstract: A display comprises a block of optically transparent materials. Patterns are etched within the block. The patterns may be selectively illuminated by light directed into sides of the block. Barriers divide the block or layers within the block into segments. Patterns in different segments and/or in different layers of the block may be independently illuminated. In some embodiments the block is made up of a number of sheets of optically transmissive material. The block may permit viewing of display elements or other objects or things located behind the block. Patterns may be configured to scatter preferentially light of specific polarizations. Displays may be applied in a wide variety of applications including in vehicles, as displays on electronic devices and the like.
