Abstract
A light control material for displaying a color image. The light control material includes a material body including a plurality of microstructures. The microstructures are designed to produce an additive color perception of one or more colors and designed to reveal an image when the intensity of light reflected from a selected number of the microstructures is modulated. The selected microstructures can be modulated by one or more of modifying, obliterating, obscuring or covering up the selected microstructures. In one embodiment, the microstructures, prior to modulation of the selected number of microstructures, produce a uniform white additive color perception.

A light control material for displaying a color, said material comprising:
- a material body including a plurality of microstructures, the microstructures designed to produce an additive color perception of one or more colors and designed to reveal an image when light reflected from one or more of the microstructures is modulated, wherein the light reflected from the one or more of the microstructures is modulated by modifying one or more of the microstructures, wherein each of said microstructures comprise a plurality of concentric steps, each step having a step height equal to about one half of a wavelength of light-forming the image.
A method for creating a light control material comprising the steps of:
- providing a material body;
- producing a plurality of microstructures therein or thereon having a periodicity to reflect a particular bandwidth of light to form an image and designed to produce an additive color perception of one or more colors, the plurality of microstructures designed to reveal an image when the intensity of light reflected from one or more of the microstructures is modulated by modifying one or more of the microstructures, wherein each microstructure is comprised of a plurality of steps, each step having a step height equal to substantially one half of a wavelength of visible spectrum light.
A light control material for displaying a color, said material comprising:
- a material body including a plurality of microstructures, the microstructures designed to produce an additive color perception of one or more colors and designed to reveal an image when light reflected from one or more of the microstructures is modulated, wherein the light reflected from the one or more of the microstructures is modulated by application of a refractive overcoating to the one or more microstructures.
