Patent ID: 10935861

Abstract:
The present disclosure relates to non-emissive modular light-diffuser devices that selectively revealing reflective material and that can be utilized in applications ranging from wearable electronics to large format displays. For example, by applying power, the modular light-diffuser devices can switch from a light-scattering state and a non-light-scattering state to reveal reflective material beneath. In particular, a modular light-diffuser device can utilize dual inputs to provide an alternating low-voltage current to a PDLC film layer (e.g., by rotating the direction of electrical polarity), thus, significantly extending the life of the modular light-diffuser device. In addition, multiple modular light-diffuser devices can be grouped and added to objects (e.g., clothing, fashion accessories, or large format displays) to form patterns, designs, and animations based on the modular light-diffuser devices changing states.
