US 2026/0227654 A1 · MULTI-COLOR LIGHT-DIFFUSER DEVICES

Abstract

Embodiments are disclosed for multi-color light-diffuser devices capable of displaying different colors based on stack configurations of polymer dispersed liquid crystal (PDLC) diffuser components, base layers, and filter layers. In one embodiment, a multi-color light-diffuser device can include a base layer positioned underneath a filter layer and a PDLC diffuser component positioned above the filter layer. In another embodiment, a multi-color light-diffuser can include an additional PDLC diffuser component in between the base layer and filter layer. The filter layer can be a dichroic material, a neutral density filter, or other transparent or semi-transparent material. The base layer can be an opaque material, such as paper, holographic film, iridescent film, or a mirror. Based on the activation of the light-scattering or non-light-scattering states of the PDLC diffuser components, the multi-color light-diffuser device can express different visual outputs based on the interactions/mixing of the filter layer and base layer.

a second PDLC diffuser component positioned above the filter layer.

1 more element

A method comprising:

receiving a first instruction to activate a light-scattering state of a first polymer dispersed liquid crystal (PDLC) diffuser component and a non-light-scattering state of a second PDLC diffuser component of a light-diffuser device, wherein a stack configuration of the light-diffuser device includes a base layer positioned underneath the first PDLC diffuser component, a filter layer positioned above the first PDLC diffuser component, and the second PDLC diffuser component positioned above the filter layer;
and
activating the light-scattering state of the first PDLC diffuser component and the non-light-scattering state of the second PDLC diffuser component, wherein activating the light-scattering state of the first PDLC diffuser component and the non-light-scattering state of the second PDLC diffuser component causes a first color to be displayed by the light-diffuser device, wherein the first color is associated with a first combination of a filter layer color of the filter layer, a base layer color of the base layer, the light-scattering state of the first PDLC diffuser component, and the non-light-scattering state of the second PDLC diffuser component.
