  • Patent number: 11149340
    Abstract: In a method for designing and fabricating a micro-lens array, a design is finalized by varying certain features of a shadow mask, varying a distance between a source of lens-forming material and the shadow mask, and varying other parameters until the features and distances result in the formation of a micro-lens having desired shape, etc. A shadow mask in accordance with the design is then fabricated and is appropriately positioned with respect to a micro-display and a source of lens-forming material. A plume of lens-forming material is then generated under reduced pressure and which propagates toward the shadow mask, directly patterning the micro-lenses on sub-pixels of the micro-display.

  • Patent number: 11009632
    Abstract: Methods are provided for forming a particular multi-layer micron-sized particle that is substantially transparent, yet that exhibits selectable coloration based on its physical properties. The disclosed physical properties of the particle are controllably selectable refractive indices to provide an opaque-appearing energy transmissive material when pluralities of the particles are suspended in a substantially transparent matrix material. Multiply-layered (up to 30+ constituent layers) particles result in an overall particle diameter of less than 5 microns. The material suspensions render the particles deliverable as aspirated or aerosol compositions onto substrates to form layers that selectively scatter specific wavelengths of electromagnetic energy while allowing remaining wavelengths of the incident energy to pass.
