  • Patent number: 9664896
    Abstract: A micro-electro-mechanical systems (MEMS) mirror array can include pre-tilted mirrors. In some implementations, a MEMS mirror array includes a set of first MEMS mirrors supported by a mounting surface of one or more first substrates, and a set of exterior MEMS mirrors supported by a mounting surface of one or more exterior substrates. The one or more exterior substrates can be disposed along at least one edge of an exterior perimeter of at least one of the first substrates. The mounting surface of the one or more exterior substrates can be arranged to cause a plane of each exterior MEMS mirror to be at a non-zero angle with respect to each first MEMS mirror. The one or more first substrates and the one or more exterior substrates can be supported by a common substrate.

  • Patent number: 9664980
    Abstract: An optical device includes an optical section, a moving section, a shaft section, and an actuator. The optical section includes a light-incident surface on which light is incident. The moving section supports the optical section and the shaft section swingably supports the moving section. The actuator swings the moving section based on a drive signal having a trapezoidal waveform. A swing waveform representative of a trajectory of the moving section as the moving section is swung has a trapezoidal waveform. A maintenance time of a flat portion of the trapezoidal waveform of the drive signal is shorter than a maintenance time of a flat portion of the trapezoidal waveform of the swing waveform of the moving section.

  • Patent number: 9612501
    Abstract: The disclosure generally relates to a front-lit display having transparent and selectively emissive light directionality. The disclosed semi-retro-reflective, semi-specular and specular displays include directional front light systems that reflect light in a manner to preserve the non-Lambertian characteristic of the light output. This leads to brighter displays with a higher degree of luminance as compared to conventional microencapsulated electrophoretic displays with substantially Lambertian reflectance where much of the light is not reflected back towards the viewer.
